Background:
Transferrin receptor, also known as CD71 or p90, is expressed at the surface of cells that utilize iron. The receptor binds transferrin and internalizes iron carried with it. Like many other proteins involved with iron metabolism, transferrin receptor is regulated by iron response element-binding proteins (IRE-BPs). Transferrin receptor is highly expressed in erythroid cells, placental tissue, and rapidly dividing cells. When iron concentration in the cells is low,IRE-BPs bind to the IREs on the mRNA of transferrin receptor to increase the transcription of the receptor.
Transferrin receptors in macrophage, T-cells and B lymphocyte are increased during activation.
Application:ELISA

2.沸水水浴10分钟后迅速冰浴
3.加入 5号试剂 2ul , 6号试剂 2ul ,7号试剂 1ul
4.37度1小时~20小时
5.中止反应 加2ul 0.2M EDTA (pH 8.0) 和/或 65度 水浴 10分钟
二、标记效率检测
(一) 试剂配置
Solution Composition Preparation
Washing buffer 0.1 M Maleic acid, 0.15 M NaCl; pH 7.5 (20° C); 0.3% (v/v) Tween 20
Maleic acid buffer 0.1 M Maleic acid, 0.15 M NaCl; adjustwith NaOH (solid) to pH 7.5 (20° C)
Detection buffer 0.1 M Tris-HCl, 0.1 M NaCl, pH 9.5 (20° C)
TE-buffer 10 mM Tris-HCl, 1 mM EDTA, pH 8.0
Blocking stock solution Dissolve Blocking reagent (bottle 10) 10% (w/v) in Maleic
(10 × conc.) acid buffer underconstantly stirring on a heating block(65°C) or heat in a microwave oven,autoclave. The solution remains opaque
Blocking solution Prepare a 1 × working solution by dilutingthe 10 × Blocking solution 1:10in Maleic acid buffer.
Antibody solution Centrifuge Anti-Digoxigenin-AP(vial 8) for 5 min at 10 000 rpm in theoriginal vial prior to each use, and pipet the necessary amount carefully from thesurface. Dilute Anti-
Digoxigenin-AP 1: 5 000 (150 mU/ml) in Blocking solution.
Colorsubstrate Add 40 _l of NBT/BCIP (vial 9) to 2 ml of Detection buffer.
solution Note: Store protected from light!
