Cat.#: 11173

Product Name: Human B7-1 Protein

Size : 10 µg, 50 µg and 100 µg

Synonyms: CD80;7;7-1;7.1;B1;D28LG;D28LG1;AB7

Target: B7-1

UNIPROT ID: P33681

Description: Recombinant Human B7-1 Protein with C-terminal Mouse Fc and 6xHis tag

Background: The protein encoded by this gene is a membrane receptor that is activated by the binding of CD28 or CTLA-4. The activated protein induces T-cell proliferation and cytokine production. This protein can act as a receptor for adenovirus subgroup B and may play a role in lupus neuropathy.

Species/Host: HEK293

Molecular Weight: The protein has a predicted molecular mass of 50.9 kDa after removal of the signal peptide. The apparent molecular mass of B7-1-mFc-His is approximately 70-130 kDa due to glycosylation.

Molecular Characterization: B7-1(Val35-Asn242) mFc(Pro99-Lys330) 6×His tag

Purity: The purity of the protein is greater than 95% as determined by SDS-PAGE and Coomassie blue staining.

Formulation & Reconstitution: Lyophilized from nanodisc solubilization buffer (20 mM Tris-HCl, 150 mM NaCl, pH 8.0). Normally 5% – 8% trehalose is added as protectants before lyophilization.

Storage & Shipping: Store at -20°C to -80°C for 12 months in lyophilized form. After reconstitution, if not intended for use within a month, aliquot and store at -80°C (Avoid repeated freezing and thawing). Lyophilized proteins are shipped at ambient temperature.
