Product Information
Product Description
CST's PathScan® Acetyl-α-Tubulin Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of acetylated α-tubulin protein. An α-tubulin mouse mAb has been coated onto the microwells. After incubation with cell lysates, α-tubulin protein (acetylated and non-acetylated) is captured by the coated antibody. Following extensive washing, an acetyl-lysine rabbit Ab is added to detect the acetylated α-tubulin protein. Anti-rabbit 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 this developed color is proportional to the quantity of acetylated α-tubulin protein.
*Antibodies in this kit are custom formulations specific to kit.
Protocol
Specificity / Sensitivity
CST's PathScan® Acetyl-α-Tubulin Sandwich ELISA Kit #7204 detects endogenous levels of acetylated α-tubulin. As shown in Figure 1 using the Acetyl-α-Tubulin Sandwich ELISA Kit #7204, a high level of acetylated α-tubulin is detected in COS cells when treated with TSA. The level of total α-tubulin (acetylated and non-acetylated) remains unchanged as shown by Western analysis (Figure 1). Similar results are obtained when NIH/3T3 and Jurkat cells are treated with TSA (data not shown). This kit detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.

Background
The cytoskeleton consists of three types of cytosolic fibers: microtubules, microfilaments (actin filaments), and intermediate filaments. Globular tubulin subunits comprise the microtubule building block, with α/β-tubulin heterodimers forming the tubulin subunit common to all eukaryotic cells. γ-tubulin is required to nucleate polymerization of tubulin subunits to form microtubule polymers. Many cell movements are mediated by microtubule action, including the beating of cilia and flagella, cytoplasmic transport of membrane vesicles, chromosome alignment during meiosis/mitosis, and nerve-cell axon migration. These movements result from competitive microtubule polymerization and depolymerization or through the actions of microtubule motor proteins (1).
