Specifications Source Cynomolgus Fc gamma RIIB Protein is expressed from HEK293 with His tag at the C-terminal. It contains Ala46-Pro224.[Accession | Q8SPW3] Molecular Weight The p rotein has a predicted MW of 21 kDa. Due to glycosylation, the protein migrates to 33-40 kDa based on Tris-Bis PAGE result. Endotoxin Less than 1EU per μg by the LAL method. Purity > 95% as determined by Tris-Bis PAGE> 95% as determined by HPLC Activity SPR Data: Trastuzumab captured on CM5 Chip via Protein A can bind Cynomolgus Fc gamma RIIB, His Tag with an affinity constant of 2.72 μM as determined in SPR assay (Biacore T200). Formulation Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. Reconstitution Centrifuge tubes 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 months, -25~-15℃ under sterile conditions after reconstitution. Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.
