目的对血小板新等位基因Caba+进行分型并调查其在中国汉族部分人群中的分布。方法采用PCR-SSP方法对无亲缘关系的健康无偿献血者进行Caba+/-基因分型。采用基因计数法进行基因频率、基因型频率的计算。结果Caba+/-阳性特征带为128bp,内对照带为429bp。本次共分型299例标本,299?
Objective To classify the platelet new allele Caba + and investigate its distribution in some Han Chinese population. Methods PCR-SSP was used to genotype Caba +/- genotypes in unrelated, healthy non-compensated blood donors. Using gene counting method for gene frequency, genotype frequency calculation. Results The Caba +/- positive band was 128 bp and the internal control band was 429 bp. The total classification of 299 specimens, 299?
