Fig. 2. Determination of recombinant zebrafish (rZf) vatB1 and vatB2 by western
blot analysis. Non-purified bacterially expressed zebrafish vacuolar ATPase
subunit B isoforms vatB1 and vatB2 were probed with (A) antibody #1034, which
recognizes both isoforms of the B subunit, and (B) antibody #1035, which is
specific for vatB1.
