DNA Extraction Method On Suture Samples For Porcine Trace Polymerase Chain Reaction (PCR) Test

The present invention disclosed a method to trace porcine DNA in a catgut suture by extracting the DNA from the catgut suture and analyzing the extracted DNA. The method of tracing porcine DNA in a catgut suture comprises steps of homogenizing the catgut suture into a mixture of plant tissue lysis buffer and proteinase K; separating the DNA from the homogenous solution the column; and analyzing the extracted DNA by using polymerase chain reaction, PCR.
