Fig. 1From: Differential expression of RNA exosome subunits in the amphibian Lithobates catesbeianus during reproductive and non-reproductive periodsExpression of L. catesbeianus RNA exosome subunits in testis in reproductive (summer) and quiescent (winter) periods. The total testis extracts were obtained from two biological samples in both periods, and subjected to western blot for detection of the RNA exosome subunits RRP40 (a), RRP42 (b), RRP43 (c), RRP6 (d) and RRP44 (e). β-actin was used as an internal control of the total protein loaded on gelsBack to article page
