Active Recombinant Human ENPEP, His-tagged

Specification :
| Source : Insect Cell | Species : Human | Tag : His | Form : Supplied as sterile 20 mM, Tris 500 mM NaCl, 10 % glycerol, pH 7.4. | Bio-activity : Measured by its ability to cleave the fluorogenic peptide substrate, Glu-7-amido-4-methyl coumarin (Glu-AMC). The specific activity is >2000 pmoles/min/μg. | Molecular Mass : The recombinant human ENPEP consists of 933 amino acids and has a calculated molecular mass of 107.2 kDa. The recombinant protein migrates as an approximately 115.5 kDa band in SDS-PAGE under reducing conditions. | Protein Length : Arg41-Gly957 | Endotoxin : | Purity : > 90 % as determined by SDS-PAGE | Storage : Samples are stable for up to twelve months from date of receipt at -20°C to -80°CStore it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles. | Reconstitution : It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
