For researchers wishing to investigate the suitability of our various chromogenic beta-glucuronidase substrates, we offer this sampler kit, which contains 5 mg each of the following three different substrates: X-GlcU, CHA, Red-beta-D-GlcU, CHA, and Rose-beta-D-GlcU, CHA.

For researchers wishing to screen for the appropriate coelenterazine derivatives to use, we offer this kit with 25 ug each of nine coelenterazine analogs: coelenterazine, coelenterazine cp, coelenterazine f, coelenterazine fcp, coelenterazine h, coelenterazine hcp, coelenterazine i, coelenterazine ip, and...

Mini syringe filters are convenient for sterile filtration of small volumes (1 mL or less) with only 10 uL retention volume. Millex(R)-GV 0.22 um hydrophilic PVDF membrane in a 4 mm filter. Kit includes sterile filters, 1 cc syringes, and screw cap vials, 5 each.

Flow Cytometry Fixation/Permeabilization Kit contains optimally formulated buffers for fixation and permeabilization of suspension cells for immunofluorescence staining of intracellular antigens for analysis by flow cytometry. Note: the fixation buffer in this kit is prepared from methanol-stabilized formaldehyde....

The TrueBlack(R) WB blocking buffer is a buffer system designed to achieve optimal specificity and sensitivity by blocking background from the non-specific interaction between the fluorophore-labeled antibodies and the membrane with cell lysates. For blocking and antibody dilution for 10 membranes.

The loss of mitochondrial membrane potential is a hallmark for apoptosis. It is an early event preceding phosphatidylserine externalization and coinciding with caspase activation. JC-1 Mitochondrial Membrane Potential Detection Kit is used to measure mitochondrial membrane potential changes in cells. In...

DAB (3,3'-diaminobenzidine) reacts with HRP in the presence of peroxide to yield an insoluble brown-colored product at locations where peroxidase-conjugated antibodies are bound to samples. The brown precipitate is insoluble in alcohol and other organic solvents, making it an excellent substrate for...

CellBrite(TM) Cytoplasmic Membrane Labeling Kits are designed to label cell cytoplasmic membranes with fluorescent dyes, available in blue, green, orange, and red. The labeling is stable and nontoxic, suitable for long-term tracking of cells. By combining multiple CellBrite(TM) Cytoplasmic Membrane Stains, one can...

The DiO/DPA system detects cytoplasmic membrane potential changes using the principle of fluorescence resonance energy transfer (FRET), where DiO is a "stationary" FRET donor while DPA acts as a potentiometric FRET acceptor. The DiO/DPA system has been reported to produce a fluorescence signal change of >56% in...

ViaFluor(R) SE Cell Proliferation Kits use amine-reactive dyes to covalently label cells throughout the cell cytoplasm and intracellular compartments. Cell proliferation dyes are commonly used to monitor cell division by flow cytometry. The dyes also can be used to stably label cells to image cell morphology, or to...

ViaFluor(R) SE Cell Proliferation Dyes are fluorescent tracers for tracking cell division by flow cytometry, ViaFluor(R) 405 SE Cell Proliferation Dye is an improved replacement for the classical proliferation dye CFSE. It can be detected in the Pacific Blue channel with violet laser excitation.

AccuOrange(TM) Protein Quantitation Kit is a highly sensitive fluorescence-based assay for quantitating purified protein samples in 96-well format. The detection range of the assay is 0.1-15 ug/mL protein. AccuOrange(TM) is much more sensitive than traditional protein quantitation assays such as BCA, Bradford and...
