The LANCE Ultra Human CCL5/RANTES Detection Kit is designed for detection and quantitation of human CCL5 in cell culture media using a homogeneous TR-FRET (no-wash steps, no separation steps) assay.
The 500 point kit contains enough reagents to run 500 wells in 384-well format, using a 20 µL reaction volume (15 µL of sample). The 10,000 point kit contains enough reagents to run 10,000 wells in 384-well format, using a 20 µL reaction volume (15 µL of sample).
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 5 (CCL5), also known as Regulated upon Activation, Normal T cell Expressed and Secreted (RANTES), is a 7.8 kDa protein that plays a primary role in the inflammatory immune response. CCL5 binds to C-C chemokine receptor (CCR) types 1, 3, and 5. CCL5 dimerization and oligomerization, as well as binding to glycosaminoglycan, are key elements of cell recruitment in the inflammation process. CCL5 is a potent chemoattractant for a number of different cell types, particularly eosinophils, basophils, and mononuclear cells. CCL5 is a potential biomarker for several diseases, for example, it can be useful for indicating the magnitude of asthmatic airway inflammation. In addition to being an important biomarker, CCL5 is studied for its interaction with its receptor, CCR5, in human immunodeficiency virus (HIV) research.

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.
