Amplifluor Probes

What are Amplifluor Probes?

Amplifluor molecular probes are designed to monitor the amplification of target DNA sequences in real time and can be used to detect specific DNA sequences during nucleic acid amplification techniques such as real-time PCR. Ampliflu probes are usually short DNA oligonucleotides with specific terminal modifications for molecular biology and genetics research. The basic structure of an Amplifluor probe consists of three components: Z-sequence, Z-primer and UniPrimer.

  • Z Sequence: An 18-nucleotide sequence used as a template.
  • Z Primer: A sequence that binds to the 5' end of the Z sequence.
  • UniPrimer: A sequence in the form of a ring in which the fluorescent reporter group and the bursting group are very close to each other.

Mechanism of Amplifluor Probes

Ampliflor probes work on the principle that when the probe is free and not bound to the target DNA, the burst of fluorescence from the fluorophore occurs due to the close proximity of the bursting agent and the fluorophore. While when the probe binds to the target DNA during PCR amplification, the burst and fluorophore separate due to a specific binding event, resulting in the emission of fluorescence and the corresponding enhancement of the fluorescence signal.

Applications of BOC Sciences' Amplifluor Probes

Gene Expression Analysis: Amplifluor probes can be used to analyze gene expression levels in different tissues, time points or conditions. By detecting the amplification of a target gene, the expression of that gene in a sample can be quantitatively measured.

Genotyping Testing: Amplifluor probes can be used to analyze single nucleotide polymorphisms (SNPs) on a target gene, which can further allow for the determination of an individual's genotype.

Mutation Detection: Amplifluor probes can be used to detect mutations associated with diseases (hereditary diseases, cancer, etc.) and provide reference for diagnosis and related drug development.

Drug Development and Screening: During the research and development of gene therapy, Amplifluor technology can be employed as a screening indicator for detecting the modulating effect of drugs on the expression of specific genes.
