Cat.No. : CD28-747H
Product Overview : Human CD28 is expressed from mammalian with a His tag and Avi tag at the N-terminal. It contains Thr17-Pro152.
Description : 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.
Source : HEK293
Species : Human
Tag : His-Avi
Form : Supplied as 0.22um filtered solution in PBS (pH 7.4).
Molecular Mass : The protein has a predicted MW of 18.2 kDa. Due to glycosylation, the protein migrates to 36-52KD based on Bis-Tris PAGE result.
Protein length : It contains Thr17-Pro152.
Endotoxin : Less than 0.01EU per ug by the LAL method.
Purity : > 95% as determined by Bis-Tris PAGE
Storage : The product should be stored at -70°C. Please do not repeated freeze-thaw cycles.
Reconstitution : It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4ºC before opening to recover the entire contents.
