The LANCE® Ultra Rat Insulin-Like Growth Factor 1 (IGF-1) Detection Kit is designed for detection and quantitation of rat IGF-1 in buffered solution and cell culture media using a homogeneous TR-FRET (no-wash steps, no separation steps) assay.
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.
Insulin-like Growth Factor 1 (IGF1 or Somatomedin C) is 70 amino acids in length after being fully processed. IGF1 is produced primarily by the liver as an endocrine hormone as well as in target tissues in a paracrine/autocrine fashion. IGF1, via binding to the IGF receptor, acts as natural activators of the AKT signaling pathway, a stimulator of cell growth and multiplication as well as a potent inhibitor of programmed cell death. IGF1 mediates many of the growth-promoting effects of growth hormone by promoting the incorporation of sulfate into cartilage in many normal tissues. The insulin-like growth factor pathway plays a major role in cancer cell proliferation, survival and resistance to anti-cancer therapies underlying the importance of IGF1 as a serum biomarker in various diseases such as diabetes and cancer.

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.
