Human Arginase 1 (ARG1) protein, also known as LCN7 and LIECF3, GenBank Accession No. NM_000045, amino acids 1-322, with a C-terminal His-tag, expressed in an HEK293 cell expression system. MW = 36 kDa.
Immunogen Region
1-322
Tag
C terminal His-Tag
Formulation
8 mM phosphate, pH 7.4, 110 mM NaCl, 2.2 mM KCl, and 20% glycerol.
Species
Human
Application
Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling
Notes
The assay was performed by UV absorption using recombinant ARG1 with thioarginine substrate (Cayman 80240). The UV absorption signal at 412 nm is proportional to the amount of reaction product produced. Reactions were conducted for 30 min at room temperature. To initiate the reaction various concentrations of ARG1 (0-100 nM final concentration) were added to ARG1 assay buffer containing the thioarginine substrate. Absorption signals were measured using a Tecan Infinite M1000 plate reader.
Avoid freeze/thaw cycles.
