Lambda Protein Phosphatase is supplied in a 20000 Units format for enzymatic dephosphorylation of proteins and related biomolecules. Lambda PP is the 221 amino-acid product of the ORF221 open reading frame on bacteriophage lambda. The enzyme is inhibited by vanadate ions and can be heat inactivated at 65 C for 1 hour in the presence of 50 mM Na2EDTA.The enzyme is useful for removing phosphate groups from serine, threonine, tyrosine, or histidine phosphorylated proteins in biochemical workflows. Applications include protein dephosphorylation, phosphoprotein cleanup, kinase assay workflows, production of unphosphorylated protein samples. Technical specifications are included below.- Quantity - 20,000 Units- Purity - greater than 90%- Activity - 600,000 Units/mg. One unit will hydrolyze 1 nmol of p-nitrophenyl phosphate, pNPP, in 1 minute at 30 C and pH 7.5 in a total reaction volume of 50 uL- Storage - -80 CThis product is for research use only.
