B7-2 Protein, Cynomolgus, Recombinant (His)

B7-1 and B7-2 are homologous costimulatory ligands expressed on the surface of antigen presenting cells (APCs). Binding of these molecules to the T cell costimulatory receptors, CD28 and CTLA-4, is essential for the activation and regulation of T cell immunity. B7-1 and B7-2 do not form hetero-oligomers, underscoring the biological relevance of dimeric and monomeric state of B7-1 and B7-2, respectively. B7-2 Protein, Cynomolgus, Recombinant (His) is expressed in HEK293 mammalian cells with C-His tag. The predicted molecular weight is 26.4 kDa and the accession number is G7NXR4.

説明

Species	Cynomolgus
Expression Host	HEK293 Cells
Tag	C-His
Accession Number	G7NXR4
別名	B72, MGC34413, LAB72, B7-2, FUN-1, B7-2 antigen, CD86, BU63, CD28LG2, B70, CD86 molecule
Construction	Tyr26-His240
Protein Purity	> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
分子量	26.4 kDa (predicted). Due to glycosylation, the protein migrates to 50-70 kDa based on Tris-Bis PAGE result.

Endotoxin	< 1 EU/μg by the LAL method.
Formulation	Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS (pH 7.4). Typically, 8% trehalose is incorporated as a protective agent before lyophilization.
Reconstitution	Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.
Stability & Storage	It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at-80℃. For reconstituted protein solutions, the solution can be stored at -20°c to -80'c for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
Shipping	In general, Lyophilized powders are shipping with blue ice.
Research Background	B7-1 and B7-2 are homologous costimulatory ligands expressed on the surface of antigen presenting cells (APCs).
