Description
Accession
Q7Z7D3
Source
Optimized DNA sequence encoding mature chain of Human B7-H4 (PHE29 - ALA258) including a C-terminal His tag was expressed in HEK293 cells.
Molecular weight
Recombinant Human B7H4 (VTCN1)is a protein consisting of 236 amino acid residue subunits,due to glycosylation migrates as an approximately as 50kDa band protein on reduced SDS-PAGE.
Purity
>95%, as determined by SDS-PAGE and HPLC
Biological Activity
The activity was tested by the ability to inhibit anti-CD3 antibody induced IL-2 secretion in human T lymphocytes. The calculated ED50 is < 0.7 ug/ml
Endotoxin
Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).
Presentation
Recombinant human B7-H4 is lyophilized from 0.2 μm filtered PBS solution, pH7.2 , 5% Trehalose.
Reconstitution
A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
Storage
Recombinant B7-H4(B7S1) can be stored in working aliquots at 2° - 8° C for one month, or at -20°C to-70°Cfor twelve months. Avoid repeated freeze/thaw cycles.
