Phospho-eIF2A (Ser51) LANCE Ultra TR-FRET Cellular Detection Kit, 500 Assay Points

LANCE Ultra phospho-eIF2A (Ser51) kits are designed for the detection of eIF2A (phosphorylated at S51) in cell lysates using a simple, homogeneous LANCE Ultra assay (no wash steps). This assay is compatible with both adherent and suspension cells.

Detail Information

Please note control lysates are NOT included in kits. Control lysates are sold separately, catalog number TRF4008S.

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).

Eukaryotic initiation factor 2 (eIF2) is a heterotrimer which is involved in the initiation of translation in eukaryotes. EIF2 binds to two other partners, GTP and Met-tRNAi, and forms the 43S pre-initiation complex upon binding the 40S subunit. Under conditions of cellular stress, the alpha subunit can be phosphorylated at S51 to downregulate protein translation.
