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.

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...

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...
