# For the DIV and nNRM indices in this assay, to achieve a power level of 0

For the DIV and nNRM indices in this assay, to achieve a power level of 0.8 requires 900 and 1100 cells respectively. CV?=?30% for all those unimodal distributions. The 2 2 bimodal distributions combine the distributions with means of 500 and Rhod-2 AM 10 and CV?=?30%, equally weighted (500+10) and with a 9010 split (500(90%)+10(10%)). Each distribution consists of 2000 random numbers. B) The same distributions as in A, logarithmically scaled. The key defines the reference points labeled around the plot (A).(TIF) pone.0102678.s002.tif (978K) GUID:?9376E25C-BA10-4D6A-9341-63029FDB6FFC Physique S3: Quantitating the Reproducibility of Intensity Measurements by Flow and Imaging Cytometry.

To assess the conversation between the IL-6 and OSM pathways, Cal33 cells were exposed to combinations of IL-6 and OSM for 15 min. Top Row) The activation of STAT3 by IL-6 alone. Left Column) The activation of STAT3 by OSM alone. The arrows point to the location of the population non-responsive to IL-6. Note that with the addition of OSM all cells treated with IL-6 show activated STAT3.(TIF) pone.0102678.s006.tif (599K) GUID:?71CE9286-9EAA-4DF0-818C-EB84EF188203 Figure S7: Evaluation of Potential indices of Diversity and Normality. A) Model distributions and cell data were used to evaluate the performance of selected metrics for characterizing the distributions. The 5050 mix consists of 2 unit normal distributions of equal populace that are separated by d standard deviations (sd). The 9010 mix consists of 2 unit normal distributions with 90% and 10% of the population, separated by d standard deviations. B) Selected Diversity and Normality indices were used to evaluate the model distributions for values of d ranging from 0C10 sd, and the Cal33 data for IL-6 and OSM stimulation. For the Cal33 data, the diversity indices all show similar response, while the model data show some key differences. The IQR (interquartile range) is not sensitive to the small 10% subpopulation, and the SE (Shannon entropy) and DE (Differential entropy, the Shannon entropy for a continuous distribution function) both plateau when the 2 2 populations individual. Only the QE (Quadratic entropy) shows a steady increase for both distributions. Again, the general pattern of the Normality steps Rhod-2 AM is similar for the Cal33 data, but the model data show key differences. The skewness and MMR (mean/median) are insensitive to the 5050 populace because it is usually symmetric, The kurtosis and KS statistic are sensitive to the variation in both distributions, however the KS was favored due to its direct interpretation as a measure of normality.(TIF) pone.0102678.s007.tif (1.0M) GUID:?BEB2DD7A-E027-4DFE-9B6B-C6FA05A35E75 Figure S8: Dose dependence of inhibitors of STAT3 activation by IL-6.

Heterogeneity indices are evaluated during assay development and thresholds decided based on the goals of the project. For drug discovery and cell/tissue profiling programs that encounter phenotypic heterogeneity, HCS images are analyzed to generate the features, statistical parameters and HI’s. For samples or treatments with low Diversity (DIV) or a normal distribution (low nNRM) standard statistics can be used. A well or sample with a high HI and high nNRM or high.
