Confocal immunofluorescent analysis of HeLa cells, untreated (left) or treated with Trichostatin A #9950 (right), using Acetyl-α-Tubulin (Lys40) (D20G3) XP® Rabbit mAb (Alexa Fluor® 647 Conjugate (red pseudocolor). Blue pseudocolor = Propidium Iodide (PI)/RNase Staining Solution #4087.
Flow cytometric analysis of HeLa cells untreated (blue) or treated with Trichostatin A (TSA) #9950 (green), using
Acetyl-α-Tubulin (Lys40) (D20G3) XP® Rabbit mAb (Alexa Fluor® 647 Conjugate).
|REACTIVITY||H M R Mk Z|
This Cell Signaling Technology antibody is conjugated to Alexa Fluor® 647 fluorescent dye and tested in-house for direct flow cytometric analysis in human cells. This antibody is expected to exhibit the same species cross-reactivity as the unconjugated Acetyl-α-Tubulin (Lys40) (D20G3) XP® Rabbit mAb #5335.
Supplied in PBS (pH 7.2), less than 0.1% sodium azide and 2 mg/ml BSA. Store at 4°C. Do not aliquot the antibody. Protect from light. Do not freeze.
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalently purified water.
NOTE: Cells should be grown, treated, fixed, and stained directly in multi-well plates, chamber slides, or on coverslips.
NOTE: All subsequent incubations should be carried out at room temperature unless otherwise noted in a humid light-tight box or covered dish/plate to prevent drying and fluorochrome fading.

Acetyl-α-Tubulin (Lys40) (D20G3) XP® Rabbit mAb (Alexa Fluor® 647 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, ZebrafishSpecies predicted to react based on 100% sequence homology:
Monoclonal antibody is produced by immunizing animals with a synthetic acetylpeptide corresponding to residues surrounding Lys40 of human α-tubulin.
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).
