Recombinant Human CD80 protein, His-Avi-tagged

Specification :
| Description : Cluster of differentiation 80 (also CD80 and B7-1) is a protein found on dendritic cells, activated B cells and monocytes that provides a costimulatory signal necessary for T cell activation and survival. It is the ligand for two different proteins on the T cell surface: CD28 and CTLA-4. | 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 26. 8 kDa. Due to glycosylation, the protein migrates to 50- 70KDa based on Bis-Tris PAGE result. | Protein length : It contains Val35-Asn242. | Endotoxin : Less than 0. 05EU per ug by the LAL method. | Purity : > 95% as determined by Tris-Bis; > 95% as determined by HPLC | 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 4℃ before opening to recover the entire contents.
