||Recombinant Human LCK (Accession # NM_005356) , fused with an N-terminal GST tag, was produced in baculovirus in Sf 9 insect cells.
||Sf 9 insect cells
||Supplied in 50 mM Tris-HCl, pH 7.5, 150 mM NaCl, 0.25 mM DTT, 0.1 mM EGTA, 0.1 mM EDTA, 0.1 mM PMSF, 25% glycerol.
||The specific activity of Lck was determined to be 180 nmol/min/mg using a Poly (Glu:Tyr, 4:1) synthetic peptide substrate
||In SDS-PAGE migrates as 84 kDa.
||The purity was determined to be >95% by densitometry
||Avoid repeated freeze-thaw cycles. No activity loss was observed after storage at: In lyophilized state for 1 year (4ºC); After reconstitution under sterile conditions for 3 months (-70ºC).
