Name : Human CD52 Protein

Product Source :
Recombinant Human CD52 Protein is expressed from HEK293 with mFc (IgG1) tag at the C-Terminus. It contains Gly25-Ser36.[Accession | P31358]

Molecular Weight :
The protein has a predicted MW of 27.6 kDa. Due to glycosylation, the protein migrates to 38-48 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 Human CD52 on Tris-Bis PAGE under reduced conditions. The purity is greater than 95%. SEC-HPLC The purity of Human CD52 is greater than 95% as determined by SEC-HPLC.

Background :
CD52, also known as CAMPATH-1 antigen, HE5, and gp20, is a cell surface glycoprotein that can be targeted to induce immune suppression by complement-mediated cell lysis. Mature human CD52 is a 12 amino acid peptide that is tethered to the cell surface with a GPI linkage.CD52 may play a role in carrying and orienting carbohydrate, as well as having a more specific role.

Synonyms :
CD52 molecule; CD52; CDW52 antigen (CAMPATH-1 antigen); CDw52; He5; HEL-S-171mP; CAMPATH-1; CAMPATH1
