可溶性白细胞介素-2受体(sIL-2R)来自活化淋巴细胞膜白细胞介素-2受体(mIL-2R)的a链成分,由255个氨基酸残基组成。sIL-2R从细胞膜脱落进入血循环,故正常人血清及尿中均存在微量的sIL-2R。我们采用夹心ELISA法测定了29例患者肺癌患者血清中的sIL-2R水平,旨在探讨sIL-2R与肺癌分
Soluble interleukin-2 receptor (sIL-2R) is derived from the a-chain component of the activated lymphocyte membrane interleukin-2 receptor (mIL-2R) and consists of 255 amino acid residues. sIL-2R is detached from the cell membrane and enters the blood circulation. Therefore, there are traces of sIL-2R in normal human serum and urine. We used sandwich ELISA to measure the serum sIL-2R levels in 29 patients with lung cancer to investigate the relationship between sIL-2R and lung cancer.
