High-content screening

High-content screening (HCS), also known as high-content analysis (HCA) or cellomics, is a method that is used in biological research and drug discovery to identify substances such as small molecules, peptides, or RNAi that alter the phenotype of a cell in a desired manner. Hence high content screening …

Pathogen Detection

The use of DNA-based methods derives from the premise that each species of pathogen carries unique DNA or RNA signature that differentiates it from other organisms. Among the various PCR strategies available, those based on monitoring the amplification reaction in real time are probably the most promising and are increasingly used for rapid, sensitive, and specific detection of microbes.
