Viral RNA Extraction Buffer (VRE100) and related reagents for qRT-PCR and additional viral RNA analyses.

Qualitative multiplex PCR assay for assessing DNA quality from FFPE tissues and other sources of damaged DNA

The assessment of DNA quality is a crucial first step in acquiring meaningful data from formalin-fixed paraffin-embedded (FFPE) tissues, and other sources of damaged DNA. Using intact genomic DNA is key for successful analysis of chromosomal aberrations (e.g. SNP analysis, LOH, aCGH, etc.).
