EBP, ELNR1, MPS4B
表达区间及表达系统（Source）
Human beta-Galactosidase-1 Protein, His Tag (BG1-H52H3) is expressed from human 293 cells (HEK293). It contains AA Leu 24 - Val 677 (Accession # P16278-1).
Predicted N-terminus: Leu 24
Request for sequence蛋白结构（Molecular Characterization）
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 75.5 kDa. The protein migrates as 80-95 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
偶联（Conjugate）
Unconjugated
内毒素（Endotoxin）
Less than 1.0 EU per μg by the LAL method.
纯度（Purity）
95% as determined by SDS-PAGE.
制剂（Formulation）
Supplied as 0.2 μm filtered solution in 50 mM Tris, 150 mM NaCl, 20% Glycerol, pH7.5 with trehalose as protectant.

电泳（SDS-PAGE）
Human beta-Galactosidase-1 Protein, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95% (With Star Ribbon Pre-stained Protein Marker).
活性（Bioactivity）
Measured by its ability to cleave a fluorogenic substrate, 4-Methylumbelliferyl-β-D-galactopyranoside. The specific activity is >1,800 pmol/min/μg, as measured under the described conditions (QC tested).
