This archive contains the level 2 RPPA data for 200 Endometrial samples and 48 
control samples (cell lines or cell line derived) 
generated by the RPPA Core Lab at the University of Texas MD Anderson 
Cancer Center.

The level 2 data are the direct output of the software SuperCurve.
 The program fits a nonlinear model (logistic, 
lowess or monotonously increasing splines) and estimate the 
IC50 of the proteins as the expression values. After this 
step, the raw signal intensity data of a sample (5 steps of dilution)
 are turned into a signal, log2 scale protein 
expression value for downstream analysis.

Since the loaded amounts of proteins can vary tremendously 
from sample to sample, especially in tumor tissue samples, 
further adjustment of this loading effect is recommended (level 3 data).
