Fluorescent dye bead
WebIn fluorescence-based assays, usually a target molecule is captured using a probe conjugated to a capture surface, and then detected using a second fluorescently labeled probe. One of the most common capture surfaces is a magnetic bead. However, magnetic beads exhibit strong autofluorescence, which … Web1.2 Fluorescent dyes. Fluorescent dyes, also known as reactive dyes or fluorophores, have been used by biologists for decades. Fluorescent dyes offer higher photostability …

WebLIVE/DEAD Fixable Viability Stain Kits are based on the reaction of a fluorescent reactive dye with cellular proteins (amines). These dyes cannot penetrate live cell membranes, so only cell surface proteins are available to react with the dye, resulting in dim staining (Figure 1, LIVE).The reactive dye can permeate the damaged membranes of dead cells and …
WebWe generated a Q-bead, Q-body-conjugated bead, with a simple three-step procedure: i) mixing the fluorescent dye and recombinant antibody fragment followed by initial purification through IMAC ii) adding the capturing bead and removing unreacted dye using pipetting-washing, and iii) Funding.
