Biotinylated Human ENPP-1 Protein, His-Avi Tag

Specifications Source Biotinylated Human ENPP-1 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Lys98-Asp925.[Accession | P22413] Molecular Weight The protein has a predicted MW of 98.29 kDa. Due to glycosylation, the protein migrates to 110-120 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 Formulation Lyophilized from 0.22μm filtered solution in 20mM Tris,150mM NaCl (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 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.   Storage The product should be stored at -25~-15℃ for 1 year from the date of receipt. 2-7 days, 2 ~ 8 °C under sterile conditions after reconstitution. 3 months, -25~-15℃ under sterile conditions after rec
