Abstract:
OBJECTIVE:To construct STR slippage model and study factors involved in this procedure.
METHODS:DNA samples were amplified with the technology of Degenerate oligonucleotide- primed PCR, then their products were taken as later DNA template and their STR genotype were analyzed by optimizing several factors.
RESULTS:STR slippage model was constructed.
CONCLUSION:Several factors were involved in the produce of STR slippage, such as amount of modulate DNA, concentration of MgCl2, property of DNA polymerase, motif sequence of STR loci, sample, etc.
