Specifications
Synonyms |
PSEC0249; CD276;B7-H3; UNQ309 |
Source |
Human B7-H3 (4Ig)/B7-H3b Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Gly27-Thr461.[Accession | Q5ZPR3-1] |
Molecular Weight |
The protein has a predicted MW of 49.5 kDa. Due to glycosylation, the protein migrates to 70-80 kDa based on SDS-PAGE result. |
Endotoxin |
Less than 1EU per μg by the LAL method. |
Purity |
> 95% as determined by SDS-PAGE and HPLC. |
Activity |
ELISA Data: Immobilized Human B7-H3 (4Ig) , His Tag at 0.5μg/ml (100μl/Well) on the plate. Dose response curve for Anti-B7-H3 Antibody, hFc Tag with the EC50 of 6.7ng/ml determined by ELISA. |
Formulation |
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
Reconstitution |
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. |
Storage
The product should be stored at -25~-15℃ for 1 year from date of receipt.
2-7 days, 2 ~ 8 °C under sterile conditions after reconstitution.
3 -6 months, -85~-65℃ under sterile conditions after reconstitution.
Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.
