分子别名（Synonym）
Hyaluronidase PH-20
表达区间及表达系统（Source）
Human Hyaluronidase PH-20 Protein, His Tag (PH0-H5225) is expressed from human 293 cells (HEK293). It contains AA Leu 36 - Tyr 482 (Accession # P38567-1).
Predicted N-terminus: Leu 36
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 53.0 kDa. The protein migrates as 60-66 kDa 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）
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM NaCl, pH7.5 with trehalose as protectant.

电泳（SDS-PAGE）
Human Hyaluronidase PH-20 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%.
活性（Bioactivity）
The activity of Human Hyaluronidase PH-20 Protein, His Tag (Cat. No. PH0-H5225) is measured by its ability to hydrolyze HA in turbidimetric assay (45 minute assay). The specific activity is >60,000 U/mg. (Unit Definition: One unit of Hyaluronidase activity will cause a change in A600 of 0.330 per minute at pH5.35 at 37 °C in a 2.0 mL reaction mixture) (QC tested).
