Recombinant Biotinylated Human CEACAM-8/CD66b Protein,His-Avi Tag

Description :
Synonyms CD66b; CEACAM8; CGM6; CD67; NCA-95 Source Biotinylated Human CEACAM-8/CD66b Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Gln35-Ser319.[Accession | NP_001807.2] Molecular Weight The protein has a predicted MW of 34.3 kDa. Due to glycosylation, the protein migrates to 60-70 kDa based on SDS-PAGE result. 内毒素Endotoxin Less than 1EU per g by the LAL method. Purity > 95% as determined by SDS-PAGE and HPLC. Activity SPR Data:Biotinylated Human CEACAM-8, His Tag immobilized on CM5 Chip can bind Human CEACAM-6, His Tag with an affinity constant of 6.13 M as determined in SPR assay . Formulation Lyophilized from 0.22 m 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 g/ml is recommended. Dissolve the lyophilized protein in distilled water.
