Protocol & Other Details
Staining with Clone RPA-T4 following permeabilization with Perm Buffer IV (1x) is not recommended for detection of CD4 on human lymphocytes. The bimodal staining pattern observed in some post-Perm IV stains results from elevated background staining.
Notes
Human Surface Marker Antibody Concentrations:
Antibody titration is critical for successful post-permeabilization staining of CD markers and other cell surface antigens. The 1X concentration represents cells stained with the recommended test size for live cell stains (see product Technical Data Sheets for test size information). The 1/4X or 1/16X concentrations represent cells stained with 1/4 or 1/16 the antibody recommended for live cell stains.
Mouse Surface Marker Antibody Concentrations:
Antibody titration is critical for successful post-permeabilization staining of CD markers and other cell surface antigens. The 1X concentration represents cells stained with the recommended test size for live cell stains. The 1/4X or 1/16X concentrations represent cells stained with 1/4 or 1/16 the antibody recommended for live cell stains.
YG PE, YG PE-Cy7, and YG PE-Cy5:
PE, PE-Cy5, and PE-Cy7 fluorochromes may be excited by either a 488-nm blue laser or a 561-nm yellow-green laser. Since excitation by the yellow-green laser improves PE detection sensitivity, data collected from the 561-nm laser detection array (YG PE, YG PE-Cy5, and YG PE-Cy7) are provided along with data from the 488-nm laser detection array (PE, PE-Cy5, and PE-Cy7) when available.
Fold-Change Statistic:
Fold-change of a channel (e.g. pStat5-PE) is calculated as the ratio between the median fluorescence intensity of the stimulated sample (e.g. IL-2) and the median fluorescence intensity of the unstimulated sample (e.g. Control).
Percentile Distance Statistic:
Percentile distance is a measure of the spread between the 95th percentile and the 5th percentile of the fluorescence intensity of a channel (e.g. CD3-FITC). The distance is calculated as the ratio between the 95th percentile of a channel and the 5th percentile of a channel in its transformed space (log, linear, arcsinh or biexponential).

Perm Buffer IV 1X vs. 0.5X:
Perm Buffer IV (provided as a 10X stock solution) may be used at a 1X or 0.5X concentration. The higher (1X) concentration provides optimal resolution of certain intracellular phosphoprotein stains but might result in increased cell loss and decreased ability to stain certain cell surface markers.
