Technology
siRNAs are used in molecular biology to silence gene expression post-transcriptionally and are widely used in functional genomics studies, therapeutic development, and drug target validation. Their ability to selectively silence genes makes siRNAs a powerful tool for understanding gene function and developing treatments for various diseases, including cancers, viral infections, and genetic disorders.
LNA’s unique chemical structure enhances the thermal stability and binding affinity to their complementary DNA or RNA sequences resulting in increased specificity and resistance to nuclease degradation compared to traditional DNA or RNA molecules. These properties make LNAs highly effective in applications such as antisense therapy, gene silencing, microRNA research, and in situ hybridization. Additionally, LNA probes are used in quantitative PCR (qPCR) assays to improve detection sensitivity and accuracy. Increased maximum annealing temperature and improved specifity and affinity in base-pairing
TaqMan™ probes is a key technology to your PCR assays providing high specificity, sensitivity, and quantification accuracy making them indispensable in research and diagnostics. We offer a wide range of dyes and quenchers at a highy competitive price.
