Recombinant Mouse B7-H2 Fc Chimera Protein, CF Summary

Purity
>95%, by SDS-PAGE under reducing conditions and visualized by silver stain
Endotoxin Level
<0.10 EU per 1 μg of the protein by the LAL method.
Activity
Measured in a competitive binding assay. When rmICOS/Fc Chimera (Catalog # 168-CS) is immobilized at 1 µg/mL (100 µL/well), rmB7-H2 inhibits 50% binding of biotinylated rhB7-H2/Fc Chimera (2.5 ng/mL) at the concentration range of 80‑120 ng/mL.

Product Datasheets

Carrier Free

What does CF mean?

CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.

What formulation is right for me?

In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Background: B7-H2

Mouse B7-H2, also called B7RP-1, B7h, LICOS, and GL50, is a member of the growing B7 family of immune co‑stimulatory proteins. Other family members include B7-1, B7-2, B7-H1 (PD-L1), PD-L2, and B7-H3. B7 proteins are members of the immunoglobulin (Ig) superfamily. The extracellular domains contain 2 Ig-like domains and all members have short cytoplasmic domains. Among the family members, they share about 20 - 25% amino acid identity. Mouse and human B7-H2 share approximately 49% amino acid identity. B7-H2 has been identified as the ligand for ICOS, a member of the CD28 family of co‑stimulatory receptors. Mouse B7-H2 is a 322 amino acid (aa) protein with a putative 46 aa signal peptide, a 233 aa extracellular domain, a 19 aa transmembrane region, and a 24 aa cytoplasmic domain. Mouse B7-H2 is expressed constitutively on resting B cells and at low levels on monocytes. The B7-H2/ICOS interaction appears to play roles in T cell dependent B cell activation and Tdifferentiation.
