||The recombinant human Fc control protein is expressed as a 227 amino acid protein consisting of Asp104 - Lys330 region of human IGHG1 (UniProt accession #P018571), which exists as a dimer under non-reducing condition.
||Supplied at 0.5 mg/ml in sterile PBS pH7.4 (carrier free & preservative free). The purified recombinant protein was labeled with Biotin (3-5 Biotin per molecule)
||Calculated molecular mass 25.6 kDa; estimated by SDS-PAGE under reducing condition 30-35 kDa probably due to glycosylation
||<0.1 eu per 1 μg of purified recombinant protein determined by the
||>95% judged by SDS-PAGE under reducing condition
