B7H7; B7-H7; HHLA2; B7 Homolog 7
Source / expression
Recombinant Human B7-H7/HHLA2 Protein is expressed from HEK293 with hFc (IgG1) tag at the C-Terminus.It contains Ile23-Asn344 [Accession | Q9UM44-1].
Molecular weight
The protein has a predicted MW of 63.7 kDa. Due to glycosylation, the protein migrates to 78-100 kDa based on Bis-Tris PAGE result.
Endotoxin
Less than 1 EU per ug by the LAL method.
Purity
> 95% as determined by Bis-Tris PAGE
> 90% as determined by HPLC
Formulation
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution
Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.
Storage
-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3 months after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
