Product Specification

Alternative Name:Phosphatase of regenerating liver 1, Protein tyrosine phosphatase type IVA 1
Source:Produced in E. coli. The catalytic domain of PRL-1 (aa 2-173) is fused at the N-terminus to a His-tag.
UniProt ID:Q93096
Formulation:Liquid. In 25mM TRIS-HCl, pH 8.0, containing 100mM sodium chloride, 0.05% Tween 20, 20% glycerol and 3mM dithiothreitol.
Purity:≥90% (SDS-PAGE)
Specific Activity:0.168U/μg. One unit will hydrolyze 1pmol para-nitrophenyl phosphate (PNPP) per minute at 37°C. Assay buffer: 50mM TRIS, pH 7.4, containing 150mM sodium chloride, 5mM dithiothreitol and 12.5mM PNPP.
Application Notes:Useful for studies of enzyme kinetics and regulation, dephosphorylation of target substrates, and inhibitor screening.
Shipping:Shipped on Dry Ice
Long Term Storage:-80°C
Use/Stability:Dilution of the enzyme followed by refreezing may lead to loss of activity.
Scientific Background:PRL phosphatases comprise a class of small oncogenic phosphatases that are prenylated at their carboxyl-termini. PRL-1 is overexpressed during cell proliferation in the liver and during differentiation of epithelial cells in the digestive tract. It augments MMP-2 and MMP-9 expression, which in turn induce cell migration and invasion.
