SYNONYMS
CD25, IL2R, TCGFR, IL-2RA, sIL-2RA, TAC antigen, sIL-2R, IDDM10, p55.INTRODUCTION
IL2-Ra is one of the three constituent subunits of the IL2 receptor.IL-2Ra is released into the serum after increased cellular expression such as increased activation of B and T cells. Clinical manifestations of IL2-Ra elevation include autoimmune conditions and some leukemias and lymphomas.
DESCRIPTION
Interleukin-2R Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 192 amino acids (22-213) corresponding to the mature IL2-R protein with an amino terminal hexahistidine tag.The IL-2R is purified by proprietary chromatographic techniques.
SOURCE
Escherichia Coli.PHYSICAL APPEARANCE
Sterile colorless liquid formulation.FORMULATION
IL-2R His-Tag protein is supplied in 1x PBS and 50% glycerol pH 7.4.STABILITY
Store at 4°C if entire vial will be used within 2-4 weeks.Store, frozen at -20°C for longer periods of time.
Please avoid freeze thaw cycles.
PURITY
Greater than 95.0% as determined by(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.

文献和实验人可溶性白介素2R (sIL-2R/sCD25 ) 酶联免疫分析 试剂盒使用说明书 本试剂仅供研究使用 目的:本试剂盒用于测定人血清,血浆及相关液体样本中可溶性白介素2R (sIL-2R/sCD25 )的含量。 实验原理: 本试剂盒应用双抗体夹心法测定标本中人可溶性白介素 2R ( sIL-2R/sCD25 )水平。用纯化的人可溶性白介素 2R ( sIL-2R/sCD25 )抗体包被微孔板,制成固相抗体
双抗体夹心ELISA法检测待测样品sIL-2R含量 【基本原理】 选用两株针对sIL-2R分子不同位点的单克隆抗体,即McAb1 (包被抗体)与McAb2 (酶标抗体)。先用McAb1 包被固相载体,使待测sIL-2R与之特异性结合,然后再加入辣根过氧化物酶(HRP)标记的McAb2 ,则形成McAb1 -sIL-2R-HRP标记McAb2 复合物,再加入HRP底物(邻苯二胺),则酶催化底物而显色,测定样品与标准品OD值,绘制标准曲线,即可从标准曲线中查得
