Abstract:
OBJECTIVETo develop a solid phase PCR method by covalent single point immobilization for recycle utilization of human genome.
METHODSPolymethacrylamide gel was selected as a solid PCR carrier based on DNA-hydrogel copolymer chemistry presented by Mirzabekov. (CH2)6NH2 amino-modified PCR product and randomly fractured formic acid-modified plasmid pGEM-T-HLA-G were used as templates. The specificity of the attachment chemistry was characterized by acrylamide gel electrophoresis, and the thermal stability of method was demonstrated by PCR. This method was applied for the recycle utilization of human genome. Sequencing was used to exclude the possibility of introduced mutations during modification and immobilization procedures.
RESULTSThe PCR detections of plasmid DNA and human genome DNA immobilized by polymethacrylamide gel was successful. The thermal stability of method was successfully demonstrated by performing PCR after 16 rounds of standard 36 PCR cycles. And the sequencing was found no mutation.
CONCLUSIONThe DNA immobilization method with polymethacrylamide gel as a solid phase carrier is stable and specific, which can be a possible approach for realizing recycle utilization of human genome for whole-genome sequencing and SNP detection.
