Name : Mouse IL-2 Protein

Product Source :
Recombinant Mouse IL-2 Protein is expressed from HEK293 with His tag and Avi tag at the N-Terminus. It contains Ala21-Gln169.[Accession | P04351-1]

Molecular Weight :
The protein has a predicted MW of 20.1 kDa. Due to glycosylation, the protein migrates to 27-30 kDa based on Tris-Bis PAGE result.

Endotoxin Level :
Less than 1EU per ug by the LAL method.

Purity :
> 95% as determined by Tris-Bis PAGE> 95% as determined by HPLC

Formulation :
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.

Reconstitution :
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.

Storage and Stability :
-20 to -80°C for 12 months as supplied from date of receipt.-80°C for 3-6 months after reconstitution.2-8°C for 2-7 days after reconstitution.Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

Product Concentration :
Tris-Bis PAGE Mouse IL-2 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SEC-HPLC The purity of Mouse IL-2 is greater than 95% as determined by SEC-HPLC. SPR Data Mouse IL-2 R alpha, His Tag immobilized on CM5 Chip can bind Mouse IL-2, His Tag with an affinity constant of 30.49 nM as determined in SPR assay (Biacore T200). Cell Based Assay Measured in a cell proliferation assay using CTLL‑2 mouse cytotoxic T cells. The ED50 for this effect is 1-5 ng/mL.

Background :
Interleukin-2 (IL-2) is an interleukin, a type of cytokine signaling molecule in the immune system. It is a 15,5 – 16 kDa protein that regulates the activities of white blood cells (leukocytes, often lymphocytes) that are responsible for immunity. IL-2 has essential roles in key functions of the immune system, tolerance and immunity, primarily via its direct effects on T cells.

Synonyms :
IL2; T-cell growth factor; TCGF; Aldesleukin
