Detect global RNA transcription temporally and spatially in both in-vitro and in-vivo with the modified nucleotide, ethynyl uridine (EU, E10345) or in kit form with Click-iT Nascent RNA capture kit, C-10365. Both approaches use powerful click chemistry detection, a simple and robust two-step technique. In step one, the alkyne-containing biomolecule is fed to cells or animals and actively incorporated into RNA. Detection utilizes the chemoselective ligation or “click" reaction between an azide and an alkyne where the modified protein is detected with a corresponding azide-containing dye or hapt...

ER-Tracker Blue-White DPX dye is a photostable probe that is selective for the endoplasmic reticulum (ER) in live cells. The cells can be aldehyde-fixed after staining with the dye but significant fluorescence signal will be lost. With excitation at ~374 nm, the environmentally-sensitive probe exhibits emission between 430 and 640 nm. A long-pass DAPI filter works best.

EdU (5-ethynyl-2’-deoxyuridine) can be used as a replacement for BrdU (5-bromo-2’-deoxyuridine) and directly measures de novo DNA synthesis or S-phase synthesis of the cell cycle using click chemistry. Click chemistry is a method of covalently coupling an azide with an alkyne. Detection of EdU employs the copper(I) catalyzed click reaction with an azide modified fluorescent dye to form a stable triazole ring. Because of the small size of the click detection reagent, no harsh denaturation steps are needed to gain access to the DNA. Eliminating this step allows for more reproducible results, a s...

The EnzChek® Lysozyme Assay Kit provides researchers with a simple and sensitive assay to measure lysozyme acitivty in solution. The assay measures lysozyme activity on Micrococcus lysodeikticus cell walls, which are labeled to such a degree with fluorescein that the fluorescence is quenched. Lysozyme action can relieve this quenching, yielding a dramatic increase in fluorescence that is proportional to lysozyme activity.

The ER-Tracker™ Red dye is cell-permeant, live-cell stain that is highly selective for the endoplasmic reticulum (ER) that when stained using the protocol provided, the staining pattern is partially retained after fixation with formaldehyde. This stain consists of the green-fluorescent BODIPY® TR dye and glibenclamide. Glibenclamide (glyburide) binds to the sulphonylurea receptors of ATP-sensitive K + channels which are prominent on ER; the pharmacological activity of glibenclamide could potentially affect ER function. Variable expression of sulphonylurea receptors in some specialized cell typ...
