Recombinant Biotinylated Human/Cynomolgus/Rhesus macaque CD28 Protein is expressed from HEK293 with His tag and Avi tag at the N-Terminus.It contains Asn19-Pro152 [Accession | P10747]. |
分子量大小(Molecular Weight)
|
The protein has a predicted MW of 18.2 kDa. Due to glycosylation, the protein migrates to 38-55 kDa based on Bis-Tris PAGE result. |
纯度(Purity)
|
> 95% as determined by Bis-Tris PAGE |
内毒素(Endotoxin)
|
Less than 1EU per μg by the LAL method. |
制剂(Formulation)
|
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
重构方法(Reconstitution)
|
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. |
存储(Storage)
|
-20 to -80°C for 12 months as supplied from date of receipt. |

-80°C for 3 months after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
CD28 is the receptor for CD80 (B7-1) and CD86 (B7-2) proteins.When activated by Toll-like receptor ligands, the CD80 expression is upregulated in antigen presenting cells (APCs). The CD86 expression on antigen presenting cells is constitutive. CD28 is the only B7 receptor constitutively expressed on naive T cells.
