Figure 2From: Identification and validation of housekeeping genes in brains of the desert locust Schistocerca gregaria under different developmental conditionsPairwise variation analysis. Pairwise variation analysis (geNorm) between normalization factors NFn and NFn+1 to determine the optimal number of reference genes required for accurate normalization in Schistocerca gregaria for brain tissue samples of (a) L5 and (b) adult animals and (c) L5 and adult samples together.Back to article page
