Acetyl-CoA Carboxylase Blocking Peptide #1062

Description

This peptide is used to block Acetyl-CoA Carboxylase (C83B10) Rabbit mAb #3676 or Acetyl-CoA Carboxylase Antibody #3662 reactivity by immunohistochemistry and Western blot.

Quality Control

The quality of the peptide was evaluated by reversed-phase HPLC and by mass spectrometry. The peptide blocks Acetyl-CoA Carboxylase (C83B10) Rabbit mAb #3676 and Acetyl-CoA Carboxylase Antibody #3662 by immunohistochemistry and Western blot.

Immunohistochemical analysis of paraffin-embedded human colon carcinoma, using Acetyl CoA Carboxylase Antibody in the presence of control peptide (left) or antigen-specific peptide (right).

Applications

Use as a blocking reagent to evaluate the specificity of antibody reactivity in immunohistochemistry protocols.

Directions for Use

For immunohistochemistry, add twice the volume of peptide as volume of antibody used in 100 μl total volume. Incubate for a minimum of 30 minutes prior to adding the entire volume to the slide. Recommended antibody dilutions can be found on the product data sheet.

Background

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).
