| 摘 要： | 用PCR方法对100例无关个体血样的apoB位点扩增片段进行研究,已发现有11个等位基因,片段长度分布于600～1100bp之间,基因频率为0.005～0.525,杂合度为70％。家系分析及对人体血液、血斑、精液、精斑、混合斑、带毛囊毛发及其它各种有核细胞组织的研究表明,该技术在个人识别及亲子鉴定上均能发挥重要作用。

| Abstract: | The polymcrphisms of apolipoprotein B (apo B) VNTR locus were typed rapidly and accurately using polymerase chain reaction (PCR). Eleven alieles were identifed in 100 unrelated individuals with a heterozygosity of 70%. The allele frequencies were 0.5～52.5%. The size of amplified fragments were from 600 to 1100 bp. It has been demonstrated that DNA typing results can be obbained from biological materiais, such as senen stains, mixed stains,various tissues, blood stains, and single hair follicle. |
