Figure 2From: Identification and expression of differentially expressed genes in the hard clam, Mercenaria mercenaria, in response to quahog parasite unknown (QPX)Relative expression by quantitative PCR of selected transcripts from SSH (hemocyte and big defensins, ferritin, RACK-1) and hemocyte (TRAF-6 and TLR) libraries. Expression levels were normalized to 18S RNA and presented as relative expression to controls (mean ± SD, n = 8 clams). * indicates significant differences of gene expression compared to controls at p < 0.05 (Student's t-test).Back to article page
