Name : Mouse ICOS/CD278 (C137S, C138S) Protein

Product Source :
Recombinant Mouse ICOS/CD278(C137S, C138S) Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Glu21-Leu144(C137S, C138S).[Accession | Q9WVS0]

Molecular Weight :
The protein has a predicted MW of 15.3 kDa. Due to glycosylation, the protein migrates to 27-38 kDa based on Tris-Bis PAGE result.

Endotoxin Level :
Less than 1EU per μg 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 ICOS (C137S, C138S) on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SEC-HPLC The purity of Mouse ICOS (C137S, C138S) is greater than 95% as determined by SEC-HPLC.

Background :
Inducible co-stimulator (ICOS), also called AILIM (activiation-inducible lymphocyte immunomediatory molecule) and CRP-1 (CD28-related protein-1), is a member of the growing CD28 family of immune costimulatory receptors. Other family members are CD28, CTLA-4 and PD-1.

Synonyms :
AILIM; CD278; CRP-1; CVID1; ICOS; MGC39850
