Lay等人曾发现人T淋巴细胞与猪红细胞形成花环,证实在人T淋巴细胞表面存在猪红细胞受体。为探讨该种受体的特性,我们观察了若干因素对人T淋巴细胞与猪红细胞花环形成的影响,现报告如下: 材料与方法猪红细胞悬液制备取抗凝猪血,用Hanks液洗涤3次,并以Hanks液配成0.5％猪红细胞悬液(约为8×10~7个细胞/毫 Lay et al. Found that human T lymphocytes and porcine erythrocytes form a rosette, demonstrating the presence of porcine erythrocyte receptors on human T lymphocytes. To explore the characteristics of this receptor, we observed the impact of several factors on the formation of human T lymphocytes and pig erythrocyte rosette, are reported as follows: Materials and methods Preparation of pig erythrocyte suspension anticoagulant pig blood, washed with Hanks solution 3 Times and Hanks solution to 0.5% pig erythrocyte suspension (about 8 × 10 ~ 7 cells / ml
