|Alternative Name||IL2RA (IL2RA ELISA Kit Abstract)|
Protein Function: Receptor for interleukin-2.
Background: CD25 is the alpha chain of the IL-2 receptor. It is a type I transmembrane protein present on activated T cells, activated B cells, some thymocytes, myeloid precursors, and oligodendrocytes that associates with CD122 to form a heterodimer that can act as a high-affinity receptor for IL-2. The IL2R gene was mapped to 10p15-p14. CD25 is expressed in most B-cell neoplasms, some acute nonlymphocytic leukemias, neuroblastomas, and tumor infiltrating lymphocytes. Its soluble form, called sIL-2R may be elevated in these diseases and is occasionally used to track disease progression.
Synonyms: Interleukin-2 receptor subunit alpha,IL-2 receptor subunit alpha,IL-2-RA,IL-2R subunit alpha,IL2-RA,TAC antigen,p55,CD25,IL2RA,
Full Gene Name: Interleukin-2 receptor subunit alphaCellular Localisation: Membrane, Single-pass type I membrane protein.

|Application Notes||Before using Kit, spin tubes and bring down all components to bottom of tube. Duplicate well assay was recommended for both standard and sample testing.|
Sequence similarities: Contains 2 Sushi (CCP/SCR) domains.
|Plate||Pre-coated,Strips (12 x 8)|
|Protocol||human CD25 ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for CD25 has been precoated onto 96-well plates. Standards (NSO,E22-C213) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for CD25 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the human CD25 amount of sample captured in plate.|
|Assay Procedure||Aliquot 0.1 mL per well of 5000pg/mL, 2500pg/mL, 1250pg/mL, 625pg/mL, 313pg/mL, 156pg/mL, 78pg/mL human CD25 standard solutions into the pre-coated 96-well plate. Add 0.1 mL of the sample diluent buffer into the control well (Zero well). Add 0.1 mL of each properly diluted sample of human cell culture supernates, serum or plasma( heparin, EDTA) to each empty well. See "Sample Dilution Guideline" above for details. We recommend that each human CD25 standard solution and each sample is measured in duplicate.|
