Overview

Product Description CHO expressed, His-tagged (C-ter) Active Human CD25 recombinant protein
Tested Application SDS-PAGE
Target Name CD25
Species Human
A.A. Sequence Glu 22 - Cys213
Expression System CHO
Activity Active

Alternate Names IL-2-RA; IL-2 receptor subunit alpha; CD25; TCGFR; TAC antigen; IL2R; CD antigen CD25; Interleukin-2 receptor subunit alpha; IL-2R subunit alpha; p55; IL2-RA; IDDM10

Properties

Form Powder
Purification Note Endotoxin level is less than 0.1 EU/µg of the protein, as determined by the LAL test.
Purity > 95% by SDS-PAGE gel and HPLC analyses.
Buffer PBS (pH 7.4)
Reconstitution It is recommended to reconstitute the lyophilized protein in sterile water to a concentration not less than 200 μg/mL and incubate the stock solution for at least 20 min at room temperature to make sure the protein is dissolved completely.
Storage Instruction For long term, lyophilized protein should be stored at -20°C or -80°C. After reconstitution, aliquot and store at -20°C or -80°C for up to one month. Storage in frost free freezers is not recommended. Avoid repeated freeze/thaw cycles. Suggest spin the vial prior to opening.
Note For laboratory research only, not for drug, diagnostic or other use.

Bioinformation

Gene Symbol IL2RA
Gene Full Name interleukin 2 receptor, alpha chain
Background The interleukin 2 (IL2) receptor alpha (IL2RA) and beta (IL2RB) chains, together with the common gamma chain (IL2RG), constitute the high-affinity IL2 receptor. Homodimeric alpha chains (IL2RA) result in low-affinity receptor, while homodimeric beta (IL2RB) chains produce a medium-affinity receptor. Normally an integral-membrane protein, soluble IL2RA has been isolated and determined to result from extracellular proteolyisis. Alternately-spliced IL2RA mRNAs have been isolated, but the significance of each is presently unknown. Mutations in this gene are associated with interleukin 2 receptor alpha deficiency.[provided by RefSeq, Nov 2009]
