설명

일반 설명

Recombinant λ PPase expressed in E. coli. A 221-amino acid, Mn²⁺-dependent, protein phosphatase. Hydrolyzes phosphate groups on serine, threonine, tyrosine, or histidine residues. Inhibited by orthovanadate. Note: 1KU = 1,000 units.

경고

Toxicity: Standard Handling (A)

단위 정의

One unit is defined as the amount of enzyme that will hydrolyze 1.0 nmol of pNPP per min at 30°C, pH 7.8. 20-200 Units will typically remove >95% of phosphates from serine/threonine residues in 0.1 nmol of protein in 30 min. 100-1000 Units will typically remove >95% of phosphates from tyrosine in 0.1 nmol of protein in 30 min.

물리적 형태

In 100 mM NaCl, 50 mM HEPES, 2 mM DTT, 0.1 mM MnCl₂, 0.1 mM EGTA, 50% glycerol, 0.01% BRIJ^® 35 Detergent, pH 7.5.

제조 메모

Further dilute in 50 mM Tris-HCl, pH 7.8, 5 mM DTT, 2 mM MnCl₂, and 100 µg/ml BSA.
