IL-23A (human) LANCE Ultra TR-FRET Detection Kit, 500 Assay Points

The LANCE® Ultra Human IL-23A Detection Kit is designed for detection and quantitation of human interleukin-23A in buffered solution and cell culture media using a homogeneous TR-FRET (no-wash steps, no separation steps) assay.

• No-wash steps, no separation steps
• TR-FRET technology
• Sensitive detection
• High reproducibility
• Faster time-to-results
• Easy automation
• 96-well, 384-well, and 1536-well formats

LANCE® and LANCE® (Lanthanide chelate excite) Ultra are our TR-FRET (time-resolved fluorescence resonance energy transfer), homogeneous (no wash) technologies. One antibody of interest is labeled with a donor fluorophore (a LANCE Europium chelate) and the second molecule 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.

IL23A, also known as human interleukin 23, is a pro-inflammatory cytokine produced by T-helper cells. Interleukin-23 is a heterodimeric cytokine composed of an IL-12p40 subunit that is shared with IL-12 and the IL-23p19 subunit. It plays major role in inflammation in disorders such as arthritis and psoriasis, and has been demonstrated as being the primary generator of inflammation in multiple sclerosis, a role previously thought to be mediated by the related cytokine interleukin 12.
