Revvity Insulin (human) LANCE Ultra TR-FRET Detection Kit

Revvity The LANCE Ultra Human Insulin Detection Kit is designed for detection and quantitation of human insulin in 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. Insulin is synthesized as a proinsulin hormone of 110 aa by Beta-cells of the islets of Langherans in the pancreas. After removal of the precursor signal peptide, proinsulin is post-translationally cleaved into two chains (peptide A of 21 aa and peptide B of 30 aa) that are covalently linked via two disulfide bonds and secreted upon increased glucose concentration in blood. Blood concentration increases from around 50 pmol/L to 300-400 pmol/L 30 min after glucose uptake. Insulin is a key player in the control of both carbohydrate and lipid metabolism and has been implicated in various diseases including diabetes, heart disease and obesity. - PEMSD
