Fig. 3From: In vitro infectivity and differential gene expression of Leishmania infantum metacyclic promastigotes: negative selection with peanut agglutinin in culture versus isolation from the stomodeal valve of Phlebotomus perniciosus M/A scatter plot of the three-replicate Pro-Pper/Pro-PNA− microarray hybridization experiment. M = (log2Ri – log2Gi) and A = [(log2Ri + log2Gi)/2], where R and G are, respectively, red (Cy5) and green (Cy3) fluorescence intensity values. Red spots represent selected clones that contain a gene up-regulated by at least 2-fold and green spots represent those down-regulated by at least 2-fold. The Pearson correlation coefficient (R2) is providedBack to article page
