Phospho-ZAP-70 (Tyr319) LANCE Ultra TR-FRET Detection Kit, 500 assay points

Please note control lysates are sold separately, catalog number TRF4024S.

Formats:

• Our 500 assay point kit allows you to run 500 wells in 384-well format, using a 20 µL reaction volume.
• Our 10,000 assay point kit allows you to run 10,000 wells in 384-well format, using a 20 µL reaction volume.

LANCE^® and LANCE^® (Lanthanide chelate excite) Ultra are homogeneous (no wash) TR-FRET (time-resolved fluorescence resonance energy transfer) technologies. One antibody of interest is labeled with a donor fluorophore (a LANCE Europium chelate) and the second antibody is labeled with an acceptor fluorophore [ULight™ dye]. Upon excitation at 320 or 340 nm, energy can be transferred from the donor Europium chelate to the acceptor fluorophore if sufficiently close for FRET (~10 nm). This results in the emission of light at 665 nm. Data are represented as ratiometric (665/615 nm X 10,000).

ZAP-70 (Zeta-chain-associated protein kinase 70) is normally expressed near the surface membrane of T-cells and natural killer cells, but levels in B-cells can be an indicator for various forms of leukemia. ZAP-70 is recruited to the TCR/CD3 complex in order to be phosphorylated. Once phosphorylated, ZAP-70 promotes downstream phosphorylation of proteins such as SLP76 and ERK.
