Figure 1. Treatment of Hep G2 cells with H2O2 stimulates phosphorylation of ACC at Ser79, detected by the PathScan® Phospho-ACC (Ser79) Sandwich ELISA Kit #7986, but does not affect the levels of total ACC detected by PathScan® Total ACC Sandwich ELISA Kit #7996. Hep G2 cells (80-90% confluent) were treated 10 mM hydrogen peroxide for 10 minutes and lysed with #7018. The absorbance readings at 450 nm are shown in the top figure, while the corresponding western blots using Acetyl-CoA Carboxylase (C83B10) Rabbit mAb #3676 (left panel) or Phospho-Acetyl-CoA Carboxylase (Ser79) Antibody #3661 (right panel) are shown in the bottom figure.Learn more about how we get our images

The PathScan® Phospho-Acetyl-CoA Carboxylase (Ser79) Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of acetyl-CoA carboxylase (ACC) when phosphorylated at Ser79. A phospho-ACC (Ser79) rabbit antibody has been coated onto the microwells. After incubation with cell lysates, phospho-ACC protein is captured by the coated antibody. Following extensive washing, an ACC mouse detection mAb is added to detect the captured ACC protein. Anti-mouse IgG, HRP-linked antibody is then used to recognize the bound detection antibody. HRP substrate, TMB, is added to develop color. The magnitude of the absorbance for the developed color is proportional to the quantity of ACC phosphorylated at Ser79.
Antibodies in kit are custom formulations specific to kit.
PathScan® Phospho-Acetyl-CoA Carboxylase (Ser79) Sandwich ELISA Kit detects endogenous levels of ACC protein when phosphorylated at Ser79 as shown in Figure 1. Kit sensitivity is shown in Figure 2. This kit detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.
Acetyl-CoA carboxylase (ACC) catalyzes the carboxylation of acetyl-CoA to malonyl-CoA (1). It is the key enzyme in the biosynthesis and oxidation of fatty acids (1). In rodents, the 265 kDa ACC1 (ACCα) form is primarily expressed in lipogenic tissues, while 280 kDa ACC2 (ACCβ) is the main isoform in oxidative tissues (1,2). However, in humans, ACC2 is the predominant isoform in both lipogenic and oxidative tissues (1,2). Phosphorylation by AMPK at Ser79 or by PKA at Ser1200 inhibits the enzymatic activity of ACC (3). ACC is a potential target of anti-obesity drugs (4,5).
