Fig. 2. Levels of the three PKB isoforms and the phosphorylation status of PKB in wild-type and PKB
/ MEFs during adipose conversion. Total cellular extracts were prepared from cells before (day 0) or at 2, 5, 8 and/or 12 days after adipose induction treatment and analysed by western blotting with PKB
-, PKBß- and PKB
-specific antibodies (A) or with phospho-PKB specific antibodies (pSer473 and pThr308) (B). Blots were reprobed with anti-actin antibodies to control for equal loading.
