Tissue specificity analysis of GmmYp1 and GmmMGP expression by Northern blot. Specific tissues were dissected from pregnant adult flies. Ten ug of tissue-specific total RNA was loaded per lane. Lanes are labeled as follows, 1: digestive tract, 2: fat body and milk gland, 3: reproductive tract, 4: larvae, 5: carcass. β-GmmTub was used as a loading control.
