Residual Host Cell DNA Size Analysis

Pharmaceutical regulatory organizations around the world recommended acceptable limits of residual DNA fragments to both the and size distribution, mostly not exceeding 10 ng/does, with a size limit of 200 bp in length.

SHENTEK Host Cell Residual DNA Size Analysis Kits are designed for quantitating different sizes of residual host cell DNA fragments, which usually target four fragment size ranges (<100 bp, 100-200 bp, 200-500 bp, to >500 bp) via DNA-specific qPCR assays. The kits are used in parallel with Residual Host Cell DNA Quantitation Kits to analyze extracted DNA from test samples using SHENTEK Residual DNA Sample Preparation Kits.
