JC-1 is a membrane permeable dye widely used for determining mitochondrial membrane potential in flow cytometry and fluorescent microscopy. This dye can selectively enter the mitochondria where it reversibly changes coloras membrane potentials increase (over values of about 80-100 mV). When excited at 488 nm, the emission shift goes from 530 nm (monomeric JC-1) to 590 nm (aggregate JC-1), which are easily detected using filter…

eFluor 514 Calcium Sensor Dye is a membrane-permeable dye used for monitoring changes in intracellular free calcium concentrations in the cell using fluorescence microscopy, flow cytometry, fluorescence spectroscopy and fluorescence microplate readers.

This reagent is intended for use in in vitro culture of B cells, monocytes, macrophages and other cells that are responsive to LPS.

The Phytohemagglutinin-L (PHA-L) Solution (500X) is a ready-to-use solution of PHA-L in aqueous buffer. PHA is a mixture of lectins isolated from the red kidney bean, Phaseolus vulgaris. PHA-L is the fraction of PHA that exhibits strong leukoagglutinating and mitogenic activity, but very little erythroagglutinating activity. This reagent is intended for use in in vitro activation of human and mouse leukocytes.

The Concanavalin A (Con A) Solution (500X) is a ready-to-use solution of Con A in aqueous buffer. Con A, isolated from the Jack bean, Canavlia ensiformis, is a lectin that binds alpha-D-glucose and alpha-D-mannose moieties found in various glycoproteins, glycolipids, and sugars and is a potent leukocyte mitogen. This reagent is intended for use in in vitro activation of human and mouse leukocytes.

The Protein Transport Inhibitor Cocktail (500X), a cocktail of Brefeldin A and Monensin, is used for assays in which prevention of protein transport to the extracellular space is desired and has been specifically formulated for use as a negative control for the Cell Stimulation Cocktail (plus protein transport inhibitors) (500X) (cat. 00-4975). Addition of this cocktail to cells in culture inhibits the intracellular protein se…

The Foxp3 Transcription Factor Fixation/Permeabilization Concentrate and Diluent solutions are used for staining with antibodies to transcription factors and nuclear proteins, such as Foxp3 and Ki-67, as well as cytokines and chemokines. It should be used in combination with the Permeabilization Buffer (10X) (cat. # 00-8333).

The Foxp3 Transcription Factor Staining Buffer Set has been formulated and optimized for staining with antibodies to transcription factors and nuclear proteins, such as Foxp3 and Ki-67, as well as cytokines and chemokines.

The Super Bright Staining Buffer is a supplement to Flow Cytometry Staining Buffer for immunofluorescent staining protocols of cells in suspension. Super Bright Staining Buffer prevents non-specific polymer interactions when more than one SuperBright conjugated antibody is used in the same experiment, which otherwise could lead to data appearing under-compensated. The buffer is provided in a convenient 5 μL/test format and is…
