Catalent’s Advanced Bioassay for Evaluating Cell Response
Summary:
Understanding transcriptional activity within cells is crucial for evaluating responses to ligands or promoter activity in transgenes or plasmids. Catalent has pioneered a relative potency bioassay using real-time quantitative reverse transcription (RT-qPCR) in a duplex format to measure transcription activity in cells treated with ligands or transgenic vectors.
Key Features:
- Duplex Format: Utilizes two fluorescent dyes with minimally overlapping emission spectra for real-time monitoring of both target and normalizer gene expression.
- Simplified Process: Eliminates the need for mRNA purification, enhancing efficiency and accuracy.
- Normalized Data: Normalizes qPCR cycle thresholds (CT) of the target transcript to the reference transcript, generating a response curve for comparison to a reference standard.
- Four-Parameter Fit Curve Analysis: Allows comparison of relative potency and assessment of suitability based on curve parallelism.
Catalent’s assay platform is reliable, accurate, and specific, offering a linear response and reproducibility. This makes it an invaluable tool for evaluating the relative potency of various test substances.
