Abstract:
Objective To study the relation between the quantity of DNA extracted by Chelex-100 method and multiplex STRs analysis.Methods DNA extracted from a variety of common forensic casework specimens were quantified by using Real-time PCR,and then amplified with AmpFLSTR IdentifilerTM PCR Amplification kit.ResultsAccording to the results of quantification,the quantities of DNA extracted from 113 samples by Chelex-100 method were adjusted to 0.5~3ng for establishing 8?l amplification system,and in this condition,most of 113 forensic casework specimens could be successfully genotyped.Conclusion When the quantity of DNA extracted by Chelex-100 method ranged from 0.5ng to 3ng,most results of multiplex STRs analysis were satisfying.Moreover,the amplification effect of 1?l DNA template was better than 3?l DNA template when the concentrations of extracted DNA were more than 0.5ng/?l.
