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. When it enters a cell, cellular esterases cleave the dye, resulting in a membrane-impermeable dye that fluoresces at ~520 nm. eFluor™ 514 Calcium Sensor Dyeis a commonly used dy…

DRAQ5, an anthraquinone dye with high affinity for double-stranded DNA, is a membrane-permeable dye that can label live or fixed/dead cells. The dye is used to distinguish nucleated and non-nucleated cells in flow cytometry, to report nuclear DNA content for ploidy and cell cycle analysis and as a nuclear counterstain nuclei in fluorescent microscopy.DRAQ5 can be excited by wavelengths from 488 to 647 nm. For microscopy/imagin…

The Cell Stimulation Cocktail (plus protein transport inhibitors) (500X) is a cocktail of phorbol 12-myristate 13-acetate (PMA), ionomycin, brefeldin A and monensin. PMA and ionomycin treatment can induce activation of many cell types to produce cytokines. Brefeldin A and Monensin result in the accumulation of secreted proteins in the endoplasmic reticulum and Golgi apparatus. The Cell Stimulation Cocktail (plus protein transp…

The Lipoploysaccharide (LPS) Solution (500X) is a ready-to-use solution of LPS from Escherichia coli 026:B6 in aqueous solution. LPS is highly immunogenic and strongly activates immune cells bearing the CD14/TLR4/MD2 receptor complex. 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.
