白细胞介素-3 (IL-3) 是一种多能造血生长因子,可以刺激祖细胞的增殖和分化。使用具有 125 I-IL-3 特异性高亲和力结合位点(分别为 KD 9.5 和 10.7 × 10−11M)的因子依赖性 NSF-60 和 FDC-P1 细胞,分离出 IL-3 表面受体。使用两种独立的亲和技术,从两种细胞类型中鉴定出的 IL-3 受体是不变的。 IL-3 受体是一种分子量为 65-70,000 道尔顿的蛋白质。
Interleukin-3 (IL-3) is a pluripotent hematopoietic growth factor which can stimulate both proliferation and differentiation of progenitor cells. Using the factor dependent NSF-60 and FDC-P1 cells, which possess specific, high affinity binding sites for125I-IL-3 (i. e.KD 9.5 and 10.7 × 10−11M, respectively) the IL-3 surface receptor has been isolated. Using two separate affinity techniques the IL-3 receptor identified from both cell types was invariant. The IL-3 receptor is a protein of molecular weight 65–70,000 daltons.
