The PY20 antibody (IgG2b) and PT66 antibody are mouse monoclonal antibodies that bind to phosphorylated tyrosine residues. Eu-W1024 labeled anti-phosphotyrosine PY20 antibody for LANCE® assays where the analyte concentration is < 1-10 nM and assay pH > 7. The PY20 antibody is a mouse monoclonal antibody, IgG2b, that binds to phosphorylated tyrosine residues.
Generic LANCE® reagents are intended for setting up homogeneous time-resolved fluorescence resonance energy transfer (TR-FRET) based assays using Eu-Chelate label as a donor and APC-labeled reagent as an acceptor. Generic reagents facilitate setting up LANCE® assays when there is a limited amount of specific reagents available or the assay reagents are relatively unstable. To enable optimization of both the signal or the noise ratio and signal stability, some of the generic reagents are labeled with two different chelates, W1024 or W8044.
LANCE® (Lanthanide chelate excite) and LANCE® Ultra are our TR-FRET (time-resolved fluorescence resonance energy transfer), homogeneous (no wash) technologies. One molecule of interest is labeled with a donor fluorophore (a LANCE Europium chelate) and the second molecule is labeled with an acceptor fluorophore [ULight™ dye, allophycocyanin (APC), etc.]. 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 (for ULight dye and APC).

Protein kinases regulate several important functions within cells including metabolism, cell cycle progression, angiogenesis, cell adhesion, etc. Specifically, mitogen-activated protein kinases (MAPK) play a central role in the cellular response to environmental stress, growth factors, and cytokines.
Generic LANCE reagents are intended for setting up TR-FRET based assays using Eu-chelate label as a donor and APC-labeled reagent as an acceptor.
LANCE Ultra and Supplier I TR-FRET reagents were compared for their capacity to deliver robust performance for EGFR and EphA4 kinase screening.
LANCE Ultra time-resolved fluorescence resonance energy transfer (TR-FRET) assays use a,proprietary europium chelate donor dye, W1024 (Eu), together with ULight™, a small,molecular weight acceptor dye with a red-shifted fluorescent emission.
