Messenger RNA (mRNA) therapeutics have emerged as a groundbreaking advance in modern medicine, enabling rapid development of vaccines, immunotherapies, and treatments for genetic disorders. Central to this technology is the production of mRNA molecules that are both stable and efficiently translated in cells. A key part of this process is mRNA capping—a biochemical modification that mimics the natural 5′ cap found in eukaryotic mRNAs. This cap plays multiple roles: it promotes efficient translation by ribosomes, protects the mRNA from rapid degradation, and helps the immune system recognize the RNA as non-threatening. Without proper capping, therapeutic mRNAs cannot function reliably, making them unsuitable for clinical use.
As the biopharmaceutical industry moves from laboratory research to large-scale production, the need for scalable, robust manufacturing has become critical. Capping approaches that work in small-scale studies may fall short when producing thousands of doses or billions of vaccine units. This article discusses the importance of scalability, introduces our scalable mRNA capping solutions, and highlights their applications across the biopharma sector, focusing on reproducibility, cost efficiency, and adherence to Good Manufacturing Practices (GMP).
The biopharmaceutical industry is experiencing a transformative shift, with messenger RNA (mRNA) therapeutics at the forefront of modern medicine. From vaccines to personalized therapies, mRNA platforms are reshaping how researchers and companies approach disease treatment. Yet, for all their promise, one critical challenge stands in the way of broad adoption: scalability. Scaling up manufacturing is not merely about producing more material; it is about ensuring consistency, quality, and cost-effectiveness as therapies move from research laboratories into clinics and eventually to global markets.
Scalability in biopharma manufacturing involves the ability to transition processes seamlessly from milligram- to kilogram-scale production while maintaining product integrity. Unlike small-molecule drugs, which benefit from decades of manufacturing experience, mRNA therapeutics are relatively new, and the infrastructure for large-scale production is still maturing. This makes scalability a central issue for companies aiming to deliver safe, effective, and affordable treatments. Below, we explore why scalability matters, particularly in terms of supporting clinical and commercial needs, ensuring reproducibility at scale, and enabling cost-effective large-batch production.
Early-stage research typically requires only small quantities of mRNA. A few milligrams may be enough to test proof-of-concept in animal models or in vitro assays. However, as drug candidates advance through the clinical pipeline, material requirements grow exponentially. A Phase I trial might require grams of material, Phase II demands tens of grams, and Phase III or commercial rollout could call for kilograms. Without scalable processes in place, meeting these escalating demands becomes a serious bottleneck.
Commercial needs introduce an even greater challenge. Once a therapy is approved, patient demand can increase dramatically. The COVID-19 pandemic highlighted how billions of vaccine doses were required globally in a short period. Meeting such demand would have been impossible without scalable manufacturing. Biopharma companies must therefore design processes that anticipate commercial-scale requirements early in development. Scalability becomes a safeguard against delays, shortages, and the need for costly process redesigns at later stages.
Reproducibility is a cornerstone of pharmaceutical manufacturing. Regulators require assurance that each production batch meets strict standards for quality, safety, and efficacy. This requirement becomes significantly more challenging when scaling up. Processes that are stable at small scale may behave unpredictably in larger systems due to changes in mixing, temperature gradients, or enzyme kinetics. Without careful design, these variations can compromise product quality.
Scalable processes address this challenge by embedding robustness and consistency into every stage of production. This includes validated raw materials, standardized operating protocols, and rigorous quality control testing. For instance, enzymatic reactions used in capping must be optimized to ensure uniform performance regardless of batch size. Chemical methods, such as co-transcriptional capping with synthetic analogs, must demonstrate consistent incorporation rates in both small- and large-scale reactions.
While quality and safety are paramount, cost cannot be ignored. Manufacturing expenses directly influence the affordability and accessibility of mRNA therapies. Inefficient or labor-intensive capping processes may be manageable at small scale but quickly become unsustainable at industrial volumes. For therapies intended for widespread use, such as vaccines, cost efficiency is critical to achieving global distribution.
Scalability plays a key role in reducing costs. Large-batch production allows companies to achieve economies of scale, where the per-unit cost decreases as output increases. For example, continuous-flow systems minimize downtime and resource waste compared to batch processing. Optimized capping chemistries reduce enzyme consumption or eliminate costly post-transcriptional modifications. Streamlined purification methods decrease material losses and processing time.
Our scalable capping services are designed to address the growing demand for robust, cost-effective, and compliant production. By offering both enzymatic and chemical workflows, embedding Good Manufacturing Practice (GMP) standards at every stage, and guiding clients through seamless scale-up from lab bench to full industry production, we provide an integrated solution that meets the diverse needs of the biopharmaceutical sector.
Capping can be performed using enzymatic methods or chemical cap analogs, each with unique advantages. A truly scalable service must provide flexibility to accommodate different project requirements. Enzymatic capping uses naturally derived enzymes such as vaccinia capping enzyme (VCE), which mimic the cell's native machinery. This approach often yields caps with very high structural fidelity, ensuring that the resulting mRNA behaves similarly to endogenous molecules. Enzymatic processes are particularly valuable in early clinical research, where precision and authenticity are essential. However, enzymatic systems can be resource-intensive, requiring careful optimization to remain cost-effective at scale.
Chemical capping relies on synthetic analogs, which can be incorporated co-transcriptionally or post-transcriptionally. These methods simplify workflows by reducing the number of steps required and often scale more readily to large-batch systems. Chemical approaches also enable customization, allowing developers to select specific cap chemistries that optimize translation efficiency or modulate immune responses for particular therapeutic applications. By offering both enzymatic and chemical options, our service provides clients with the ability to tailor capping strategies to their therapeutic goals. Some projects may prioritize the biological fidelity of enzymatic caps, while others benefit from the scalability and efficiency of chemical workflows. The availability of both ensures that no matter the project's stage or scope, the capping process remains adaptable.
Producing capped mRNA for clinical or commercial use requires strict adherence to Good Manufacturing Practice (GMP). GMP is more than a regulatory framework; it is the foundation for ensuring patient safety and product reliability. Every reagent, piece of equipment, and environmental condition must meet validated standards, and every step of the process must be documented and auditable. Our facilities operate under full GMP compliance, providing confidence that capped mRNA produced within them is suitable for clinical trials and eventual market distribution. This compliance covers raw material qualification, in-process controls, environmental monitoring, and batch-release testing. Whether the workflow involves enzymatic enzymes or synthetic cap analogs, GMP ensures that the final product is consistent, sterile, and safe.
Moreover, GMP compliance provides a strategic advantage for developers. By embedding GMP standards from the outset, companies avoid the delays and costs associated with revalidating processes later in development. Early adoption of GMP-aligned workflows means that the same capping process can support preclinical, clinical, and commercial stages without interruption. For clients, this translates into smoother regulatory submissions, accelerated timelines, and fewer compliance risks.
Scaling up a capping process from milliliter-scale laboratory reactions to liter- or even hundred-liter industrial systems is one of the most challenging aspects of mRNA manufacturing. Variables such as enzyme kinetics, reagent mixing, and reaction control behave differently at larger volumes. Without careful optimization, processes that seem efficient at bench scale may falter when applied to industrial production.
Our services bridge this gap through a structured, stepwise approach to scale-up. Beginning with pilot-scale feasibility studies, we test how laboratory methods translate into intermediate production volumes. Data from these studies inform adjustments in mixing strategies, reaction times, and purification protocols. Once optimized, the process is validated for consistency and reproducibility before moving into full-scale manufacturing.
This approach minimizes risk during scale-up, ensuring that every stage of development is supported by reliable data. It also allows clients to plan for the long term: a method validated at pilot scale provides a direct pathway to industrial deployment. By partnering with us, companies gain not just technical expertise but also strategic guidance on how to align scale-up with regulatory expectations, supply chain readiness, and market demands.
