Quantification of Circulating Pig-Specific DNA in the Blood of a Xenotransplantation Model07:34

Quantification of Circulating Pig-Specific DNA in the Blood of a Xenotransplantation Model

In this protocol, porcine specific primers were designed, plasmids-containing porcine specific DNA fragments were constructed, and standard curves for quantitation were established. Using species-specific primers, cpsDNA was quantified by qPCR in pig-to-mouse cell transplantation models and pig-to-monkey artery patch transplantation...
