Thirty-five weak A samples including fourteen A, eight A, seven A, three A and three A were studied in order to determine their A antigen site density, using an IgG anti-A labelled with I. The values obtained ranged between 30,000 A antigen sites for A individuals, and 700 sites for the A red cells. The hierarchy of values observed made it possible to establish a quantitative relationship between the red cell agglutinability of these phenotypes measured under standard conditions, and their antigen site density.
为了确定35份弱A样本的A抗原位点密度，使用用碘标记的IgG抗A对其中的14份A、8份A、7份A、3份A和3份A进行了研究。得到的值在A个体的30,000个A抗原位点到A红细胞的700个位点之间。观察到的值的层次结构使得能够在标准条件下测量的这些表型的红细胞凝集性与其抗原位点密度之间建立定量关系。
