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).
STAT3 is an important transcriptional activator, and is involved in regulating cytokines and growth factor receptors. STAT3 is phosphorylated at Tyr-705 by the JAK pathway, upon which STAT3 will dimerize, translocate to the nucleus, and bind DNA. In some cancers STAT3 is shown to be constitutively activated. It has been implicated in both anti-apoptotic and oncogenic pathways.
