title: Identification of pyruvate carboxylase in 3T3-L1 cells by transblot and its correlation with differentiation into adipocytes.
abstract: The 3T3-L1 preadipocytes treated with insulin, dexamethasone and 3-methyl-1-isobutylxanthine (IBMX) two days before reaching monolayer undergo differentiation into adipocytes. Cell lysates were prepared from these cells under various conditions and analyzed by SDS-PAGE and transblot. Peroxidase-conjugated avidin used to detect endogenous proteins interacted strongly with a protein with an estimated molecular weight of 120 kDa, corresponding to pyruvate carboxylase, in the differentiated 3T3-L1 cells. On the other hand, this protein was not detected in undifferentiated 3T3-L1 cells.
