Non disponible en dehors du Royaume-Uni et de l'Irlande

Application

Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling

General description

Human Jak2 (GenBank Accession No. NM_004972), containing the catalytic and the pseudo kinase domain (amino acids 532-1132) with N-terminal GST-His tag, MW = 99 kDa, expressed in a Baculovirus infected Sf9 cell expression system.

Physical form

Formulated in 25 mM Tris-HCl, pH 8.0, 100 mM NaCl, 0.05% Tween-20, 50% glycerol and 3 mM DTT.

Preparation Note

Thaw on ice. Upon first thaw, briefly spin tube containing enzyme to recover full content of the tube. Aliquot enzyme into single use aliquots. Store remaining undiluted enzyme in aliquots at -70°C. Note: Enzyme is very sensitive to freeze/thaw cycles.

Unit Definition

One unit is defined as the amount of enzyme that will phosphorylate 1 nmol of tyrosine substrate per minute at pH 7.4 and 30°C.
