Biotinylated Human Fc gamma RIIA/CD32a (H167) Protein, His-Avi Tag

Specifications Source Recombinant Biotinylated Human Fc gamma RIIA/CD32a (H167) Protein is expressed from HEK293 with His tag and Avi tag at the C-terminal. It contains Ala36-Ile218(H167).[Uniprot  | P12318-1] Molecular Weight The protein has a predicted MW of 23.2 kDa. Due to glycosylation, the protein migrates to 30-40 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 and  HPLC Activity SPR Data: Biotinylated Human Fc gamma RIIA (H167) , His-Avi Tag captured on CM5 Chip via Anti-his antibody can bind Rituximab with an affinity constant of 1.44 μM as determined in SPR assay . SPR Data: Rituximab captured on CM5 Chip via Protein A can bind Biotinylated Human Fc gamma RIIA (H167) , His-Avi Tag with an affinity constant of 0.680 μM as determined in SPR assay Formulation Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant
