LTK Kinase Enzyme System
Recombinant human LTK (498-796) was expressed by baculovirus in Sf9 insect cells using an N-terminal GST tag. LTK is a member of the ros/insulin receptor family of tyrosine kinases. The LTK gene encodes a putative transmembrane protein-kinase devoid of an extracellular domain and it may encode a signal transduction subunit for one or more of the hematopoietic receptors. ADP-Glo Kinase Assay is a luminescent kinase assay that measures ADP formed from a kinase reaction; ADP is converted into ATP, which is a substrate in a reaction catalyzed by Ultra-Glo Luciferase that produces light. The luminescent signal positively correlates with ADP amount and kinase activity. The assay is well suited for measuring the effects chemical compounds have on the activity of a broad range of purified kinases, making it ideal for both primary screening as well as kinase selectivity profiling. The ADP-Glo Kinase Assay can be used to monitor the activity of virtually any ADP-generating enzyme (e.g., kinase or ATPase) using up to 1mM ATP.
