The SHENTEK® Animal-derived Biomaterial Residual DNA Sample Preparation Kit utilizes magnetic particle separation technology to extract residual DNA from a broad range of animal-derived biomaterials. This kit is suitable for the efficient and reproducible recovery of residual DNA in complex sample matrix, including but not limited to extracellular matrix, collagen and bio-absorbable membrane. The extracted DNA allows for downstream applications of residual DNA quantitation using qPCR or PicoGreen analysis. This kit is compatible with manual sample preparation or automated extraction with rHCDpurify instrument.
