Figure 1. Relationship between protein concentration of lysates from untreated and H2O2-treated Hep G2 cells and immediate light generation with chemiluminescent substrate is shown. Hep G2 cells (80-90% confluent) were treated with H2O2 (10 mM, 10 min) and lysed with PathScan® Sandwich ELISA Lysis Buffer (1X) #7018. Graph inset corresponding to the shaded area shows high sensitivity and a linear response at the low protein concentration range.

The PathScan® Phospho-Acetyl-CoA Carboxylase (Ser79) Chemiluminescent Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of acetyl-CoA carboxylase (ACC) protein phosphorylated at Ser79 with a chemiluminescent readout. Chemiluminescent ELISAs often have a wider dynamic range and higher sensitivity than conventional chromogenic detection. This chemiluminescent ELISA, which is offered in low volume microplates, shows increased signal and sensitivity while using smaller samples. 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. Chemiluminescent reagent is added for signal development. The magnitude of light emission, measured in relative light units (RLU), is proportional to the quantity of phospho-ACC (Ser79) protein.
Antibodies in kit are custom formulations specific to kit.
NOTE: Refer to product-specific datasheets for assay incubation temperature. This chemiluminescent ELISA is offered in low volume microplates. Only 50 μl of samples or reagents are required in each microwell.
NOTE: Prepare solutions with purified water.
*NOTE: Some PathScan® ELISA Kits may include HRP-Linked Streptavidin in place of HRP-Linked Antibody.

PathScan® Phospho-Acetyl-CoA Carboxylase (Ser79) Chemiluminescent Sandwich ELISA Kit recognizes endogenous levels of phospho-ACC (Ser79) in human cells. 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).
