Residual DNA size by Southern blot

Avance Biosciences offers Southern blot service to determine the size distribution of residual DNA contaminants in various steps of biologics manufacturing processes. DNA extracted from testing samples are separated by Agarose gel electrophoresis and detected by Southern blotting using a 32P labeled probe.

Residual DNA size distribution can also be analyzed by using qPCR methods.
