Recombinant Human CD89 Protein

Product Overview Description Recombinant Human CD89 Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Gln22-Asn227. Purity > 95% as determined by Tris-Bis PAGE;> 95% as determined by HPLC Accession NP_001991.1 Target Symbol CD89 Synonyms IgA Fc receptor; CD89; FCAR; CTB-61M7.2; FcalphaRI; Fc fragment of IgA Species Human Expression System HEK293 Tag C-His Expression Range Gln22-Asn227 Mol. Weight The protein has a predicted MW of 24.6 kDa. Due to glycosylation, the protein migrates to 45-65 kDa based on Tris-Bis PAGE result. Form Lyophilized Formulation Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. Endotoxin Less than 1EU per ug by the LAL method. Storage Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
