自1976年Morgan等报告,在致分裂原刺激的淋巴细胞培养上清中存在一种因子,能维持激活后的T细胞在体外长期生长以来,对于IL—2的产生、理化特性、纯化及基因工程的研究,近年来已成为国内、外许多免疫工作者所热衷的课题。本文报告了人扁桃体IL—2的产生,并探讨了在其保存过程中温度对它的影响。 Since 1976, Morgan et al. Report that there is a factor in the original schizotypal lymphocyte culture supernatant that can maintain the production, physicochemical properties, purification and gene expression of IL-2 since long-term growth of activated T cells in vitro In recent years, engineering research has become a topic that many immunologists at home and abroad are keen on. This paper reports the production of human tonsil IL-2 and explores the effect of temperature on it during storage.
