Total STAT3 LANCE Ultra TR-FRET Cellular Detection Kit, 500 Assay Points

LANCE Ultra total STAT3 kits are designed for the detection of total STAT3 (phosphorylated and unphosphorylated) in cell lysates using a simple, homogeneous LANCE Ultra assay (no wash steps). This assay can be used as a normalization assay for phospho-STAT3, and is compatible with both adherent and suspension cells.

For research use only; not for diagnostic procedures. All products to be used in accordance with applicable laws and regulations including without limitation, consumption & disposal requirements under European REACH regulations (EC 1907/2006).

Overview

Please note control lysates are NOT included in kits. Control lysates are sold separately, catalog number TRF4004S.

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).

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.

Application Brief

Eight Limitations of ELISA and How to Overcome Them Using Alternative Technologies

The introduction of enzyme-linked immunosorbent assays (ELISAs) in the early 1970’s offered researchers a non-radiometric immunoassay platform without compromising sensitivity. Over the last 50 years scientists have made huge strides in disease research and drug discovery and a demand for greater assay throughput and sensitivity has evolved. In response, more robust immunoassays have been developed to address some of the limitations of the standard, colorimetric ELISA.

Find out about the most common limitations of traditional ELISAs and how different ELISA alternative technologies address these limitations.
