Figure 4From: A trehalose 6-phosphate synthase gene of the hemocytes of the blue crab, Callinectes sapidus: cloning, the expression, its enzyme activity and relationship to hemolymph trehalose levelsChanges in the levels of trehalose in hemolymph and TPS activity in hemocytes during molt cycle. Data is presented as mean ± 1 SE (n = 8–15) of trehalose in mg/ml hemolymph (solid bar) and of TPS enzyme in μmol/h/mg protein in hemocyte extracts (open bar). Statistical significances at P < 0.05 marked as + (trehalose) or * (TPS activity) were determined using Student's t test by comparing the values at intermolt stage with each different molt stage. I.M = intermolt, P.M = premolt, E.E = early ecdysis, L.E = late ecdysis, A = within 3 h after ecdysis, B = 1–2 days after ecdysis, C1–3 = 3–7 days after ecdysis, and I.M* = same as I.M.Back to article page
