Summary of the number of transmembrane helices present in proteins identified in the DT phase, in comparison to the AQ phase, the recovered Pt, and control non-enriched tissue.

Numbers for each of the Triton X-114 fractions are based on the average of two samples. Results indicate a clear increase in the number of transmembrane domains present in proteins from the DT phase, with a 2.3 fold increase (194/83) in the number of transmembrane proteins identified in comparison to control non-enriched tissue. The number of helices present in the protein lost to the Pt fraction, and in that of the control sample are very similar, as expected, and is in keeping with the protein banding pattern observed in Figure 2.
