Revvity Host Cell Residual DNA contamination LANCE Ultra Detection Kit

Revvity The LANCE Ultra Residual DNA Contamination Detection Kit is designed for detection and quantitation of contaminating DNA 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. Biologics can be impacted negatively by contamination with DNA introduced during fermentation and purification processes. While the use of serum-free media in the manufacturing process significantly improved the success rate on preventing DNA impurities, other routes of contamination, such as microbial contamination, still remain a concern. It is thus critical to remove and monitor DNA impurities at each step in the purification process. This kit is designed to quantify the levels of DNA (from different hosts, either double- or single-stranded and of varying fragment sizes) in cell culture supernatants. - PEMSD
