title: [Constructing of STR slippage model by optimizing some factors].
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.
  
  
  CONCLUSIONS
  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.
