为了深入研究T、B淋巴细胞的生物学特性和功能．常需从淋巴细胞群体中分离出单一的T细胞或B细胞，以满足实验要求。我们根据T淋巴细胞膜表面标志，用高梯度磁场，应用免疫磁珠法分离外周血T淋巴细胞，分离效率高。l材料和方法l．l材料包被羊抗鼠IyG免疫磁珠（挪威Dynal公司产品
In order to further study the biological characteristics and functions of T, B lymphocytes. It is often necessary to isolate a single T cell or B cell from a lymphocyte population to meet the experimental requirements. According to the T lymphocyte membrane surface markers, we use high-gradient magnetic field to separate peripheral blood T lymphocytes by using immunomagnetic beads method, and the separation efficiency is high. l Materials and methods l. l material wrapped goat anti-mouse IyG immunomagnetic beads (Norway Dynal products
