Preliminary study on three kinds of method of interleukin 1 (IL-1) assay / 中国免疫学杂志

In present paper,we studied three kinds of method of assay for IL-1:thymocyte proliferation assay;L_(?) cell proliferation assay and pyrogen assay.Stimultaneously we used ~(125)I-UdR in stead of ~3H-TdR.The results show that all of three kinds of method of assay for IL-1 can measure IL-1 activity of supernatants from cultured rat alveolar M? stimulated by LPS in vitro.It suggests that ~(125)I-UdR can incorporate into DNA synthesis of cell and mouse fibroblast cell line L_(?) can response to IL-1 of supernatant from cultured rat alveolar M? stimulated by LPS.
