Monoclonal Antibody for studying tubulin alpha (Lys40) acetylate. Validated for Western Blotting. Highly specific and rigorously validated in-house, Acetyl-alpha-Tubulin (Lys40) (D20G3) Rabbit Monoclonal Antibody (HRP Conjugate) (CST #14652) is ready to ship. Product Usage Information Western Blotting: 1:1000 Storage Supplied in 136 mM NaCl, 2.6 mM KCl, 12 mM sodium phosphate (pH 7.4) dibasic, 2 mg/ml BSA, and 50% glycerol. Store at -20°C. Do not aliquot the antibodies. Protocol Available protocols: Western Blotting Specificity / Sensitivity Acetyl-alpha-Tubulin (Lys40) (D20G3) Rabbit Monoclonal Antibody (HRP Conjugate) detects endogenous levels of α-tubulin only when acetylated at Lys40. This amino acid is not conserved in β-tubulin. Species Reactivity: Human, Mouse, Rat, Monkey, Zebrafish Source / Purification Monoclonal antibody is produced by immunizing animals with a synthetic acetylpeptide corresponding to residues surrounding Lys40 of human α-tubulin protein. 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). The Elongator complex catalytic subunit (Elp3) acetylates α-tubulin at Lys40 while the histone deacetylase HDAC6 functions as a tubulin deacetylase. This post-transcriptional modification may be required for dynamic cell shape remodeling, cell motility, tubulin stability and terminal branching of cortical neurons (2,3).
