Table 2 In the S10B FE of grk, distinct transversal Vmem- and pHi-gradients are missing

From: Bioelectrical and cytoskeletal patterns correlate with altered axial polarity in the follicular epithelium of the Drosophila mutant gurken

  1. §Transversal gradients (fluorescence intensity ratios FE2/FE1; larger value vs. smaller value), and #a-p gradients (fluorescence intensity ratios pFE/aFE) in the S10B FE of wt and grk were quantified as shown in Fig. 1e (for variability see Additional file: Tables S1 and S2). The higher the fluorescence intensity ratio is, the steeper is the gradient (n = 7; see als Fig. 3b and c). Since, in grk, the cFC and mFC (refering to aFE) are often both more hyperpolarised and more acidic than the aberrant pFC, a-p gradients in grk seem to be somewhat steeper than in wt (cf. Additional file: Fig. S1 and Table S2), but this difference was not significant (cf. Fig. 3c)
