Relying on professional technology and advanced equipment, BOC Sciences focuses on the development of LNA probes to provide high-quality nucleic acid probe synthesis services and related product development. Our team has optimized the synthesis process, improved the production flow, and has the ability to produce from OD grade to gram scale to best meet our customers' needs.
LNA (locked nucleic acid) has a strong affinity for DNA, RNA and increased Tm value, thus allowing the design of probes with shorter sequences, increased sensitivity to single base mismatches, and application to SNP genotyping for the identification of 1-base differences. Compared to traditional nucleic acid probes, LNA probes have high specificity and sensitivity and are commonly used for the detection and analysis of DNA or RNA sequences. It can bind to target-specific sequences to improve the specificity of hybridization. This high specificity and sensitivity make LNA probes highly accurate in biological experiments such as detection of gene mutations, gene expression, and nucleic acid sequence analysis.

When creating LNA probes, BOC Sciences researchers select nucleic acid sequences with high specificity and sensitivity, and then bind them to the lock nucleic acid. This binding allows the LNA probe to more accurately recognize the target nucleic acid sequence and better bind to it. We can provide customized oligo synthesis services according to the customer's design sequence or LNA modification requirements, such as modification sites, quantity, and phosphorylation needs.
