Figure 1. 2D-DIGE comparison of two E. histolytica HM-1∶IMSS strains.

Figure 1

2852 spots were identified in this gel representing whole cell lysates from two strains of E. histolytica HM-1∶IMSS separately prepared. One was maintained in Saint Louis, Missouri, USA, and the other in London, England. Using a three-fold cutoff, only 6 labeled protein spots were found to fluoresce at different levels, suggesting limited biological variation exists between preparations and isolates. White spots are indicative of identical protein amounts; blue represents increased abundance in the Saint Louis isolate, while yellow represented increased abundance in the London isolate.
