Protein Description	Recombinant Human B7-1Fc is a homodimeric B7-1 fusion protein, whose monomer contains a total of 441 amino acid residues, consisting of 211 amino acid residues corresponding to the extracellular domain of human B7-1, fused to the Fc portion of human IgG1. The calculated molecular weight of the B7-1 Fc monomer is 50.0 kDa.
Note	Centrifuge the vial prior to opening!
Storage	Store lyophilized at 2-8°C for 6 months or at -20°C long term. After reconstitution store the antibody undiluted at 2-8°C for one month  or (in aliquots) at -20°C long term. Avoid repeated freezing and thawing.
Stability	Shelf life: one year from despatch.
Bioactivity	Biological: Determined by its ability to inhibit alkalinephosphatase activity in differentiating MC3T3/E1 cells. The expected ED50 for this effect is 0.5-1.5 μg/ml.
Endotoxin	< 0.1 ng per µg (1EU/µg)

Summary	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. [provided by RefSeq, Aug 2011]
