Product Information
KE10208 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The mouse CD25/IL-2RA ELISA kit is to be used to detect and quantify protein levels of endogenous mouse CD25/IL-2RA. The assay recognizes mouse CD25/IL-2RA. An antibody specific for mouse CD25/IL-2RA has been pre-coated onto the microwells. The mouse CD25/IL-2RA protein in samples is captured by the coated antibody after incubation. Following extensive washing, another horseradish peroxidase (HRP)-conjugated antibody specific for mouse CD25/IL-2RA is added to detect the captured mouse CD25/IL-2RA protein. For signal development, followed by Tetramethyl-benzidine (TMB) reagent. Solution containing sulfuric acid is used to stop color development and the color intensity which is proportional to the quantity of bound protein is measurable at 450 nm with the correction wavelength set at 630 nm.

Background Information
CD25, also known as the α chain of the IL-2 receptor (IL-2Rα), is a key regulator of T cell function. It is expressed in activated T cells and has been implicated in regulating various immune and autoimmune responses. Its deficiency has been associated with autoimmune phenomena including autoimmune enteropathy and bullous pemphigoid. The soluble CD25 can be found in the serum and may have implications for human disease in both cancer and chronic infection.

FAQ
1、我的样本稀释液有限,如何处理稀释倍数较大的样本?
我们建议您对样本进行梯度稀释。例如,人血清样本需要1000000倍稀释时,您可以分3个梯度,每个梯度100倍,进行稀释:
第一步:取2 uL人血清样本,加入198 uL样本稀释液,混匀得到100倍稀释的人血清样本
第二步:取2uL 100倍稀释的人血清样本+ 198 uL样本稀释液进行稀释,混匀得到10000倍稀释的人血清样本
第三步:取2uL 10000倍稀释的人血清样本+ 198 uL样本稀释液进行稀释,混匀得到1000000倍稀释的人血清样本。
如果样本需要进一步稀释,您可以使用更多梯度。除了我们推荐的样本稀释液,不建议您使用其他溶液或者水稀释。如果您的样本稀释液仍然不足,请联系我们的客服为您提供更多样本稀释液。

文献和实验含量。 【材料和试剂】 (1) 纯化或重组的IL-2R蛋白(α链,P55,CD25,Tac抗原)(40.000u/ml) (2) FITC标记的抗IL-2R McAb(0.2μg/ml):FITC为异硫氰酸荧光素,这里仅作为半抗原使用,而不作为荧光素标记。 (3) 碱性磷酸酶标记的兔抗FITC抗体(酶标抗体) (4) 对硝基苯磷酶盐底物液;用pH9.8的二乙醇胺缓冲液溶解,配成浓度为1mg/ml
Rosa26-EYFP(CD4/EYFP)小鼠脾细胞中观察到,未经处理的活细胞EYFP荧光信号最强;然而,使用FoxP3染色试剂盒(含Fix/Perm和Perm两步法)后,EYFP荧光几乎完全消失。值得注意的是,若在标准染色流程前先用2%多聚甲醛(PFA)进行预固定,则EYFP信号可有效保留。 这一现象表明,荧光丢失并非源于荧光蛋白的化学降解,而是由于Fix/Perm缓冲液固定能力不足,导致可溶性胞质EYFP在后续破膜和洗涤步骤中被被动洗脱出细胞。 怎样解决
