Supplied in 10 mM NaH2PO4, 150 mM NaCl, 0.09% NaN3, 0.1% gelatin, pH 7.2. This product is stable for 12 months when stored at 4ºC. Do not aliquot the antibody. Protect from light. Do not freeze.
This antibody has been validated for Flow Cytometry using the FoxP3/Transcription Factor Fixation/Permeabilization Kit #43481. Please refer to the protocol provided with the kit for detailed instructions.
Protocol Id: 1804
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalent grade water.
NOTE: When including fluorescent cellular dyes in your experiment (including viability dyes, DNA dyes, etc.), please refer to the dye product page for the recommended protocol. Visit www.cellsignal.com for a full listing of cellular dyes validated for use in flow cytometry.
NOTE: Count cells using a hemocytometer or alternative method.
NOTE: If using whole blood, lyse red blood cells and wash by centrifugation prior to immunostaining.
NOTE: Human Fc receptors cross-react with rabbit IgG. When cells of interest express high levels of Fc receptor protein (for example, macrophage/monocyte lineages), pre-incubate live cells with human Fc block prior to immunostaining with rabbit antibodies.
NOTE: Optimal centrifugation conditions will vary depending upon cell type and reagent volume. Generally, 150-300g for 1-5 minutes will be sufficient to pellet the cells.
