Revvity CCL4 (human) LANCE Ultra TR-FRET

Revvity The LANCEUltra Human CCL4/MIP-1 Detection Kit is designed for detection and quantitation of human CCL4/MIP-1 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. C-C Motif Chemokine 4 (CCL4), also known as Macrophage Inflammatory Protein-1beta (MIP-1), is a 69 amino acid chemokine signaling through the CCR5 receptor. It is a chemoattractant for natural killer cells, monocytes, and a variety of other immune cells. CCL4 is also an important regulator of macrophage migration. CCL4 is rapidly synthesized by activated T cells, B cells, and monocytes. It is also produced by neutrophils after adhesion to the laminin contained in the basement membrane of blood vessels. It is one of the major HIV-suppressive factors produced by CD8+ T-cells and has been reported to show a direct antiviral activity against HSV-1. Recombinant CCL4 also induces a dose-dependent inhibition of different strains of HIV-1, HIV-2, and simian immunodeficiency virus. - PEMSD (Additional S&H or Hazmat Fees May Apply)
