Fig. 3. Semiquantitative RT-PCR analysis of V-type H+-ATPase (VHA) mRNA
abundance in sternal epithelial cells of Porcellio scaber during the
mineralizationdemineralization cycle. (A) Demonstration of
template-dependent quantification of VHA B-subunit mRNA. (B) Relative
expression of PMCA in the anterior (ASE) and posterior sternal epithelium
(PSE).
