Microtubules are cell constituents that display several astounding properties and a unique pattern of behavior during the cell cycle. Microtubules are regulated by several proteins and complexes, and it has long been the endeavor of cell biologists to delineate how tubulin works, how this protein is regulated, and the impact of these mechanisms on the function of microtubules.
Some commonly used assays include immunofluorescent imaging tests using specific antibodies, or agents which lead to alterations of several different components of microtubules. Abcam can provide the appropriate tools for the study of various different microtubular processes.

Immunocytochemistry of formaldehyde-fixed HeLa cells stained with anti-beta tubulin antibody (ab6046). The secondary antibody (green) was ab150081 Alexa Fluor® 488 goat anti-rabbit IgG. Nuclear DNA was labeled with DAPI (shown in blue). The negative control is a secondary only assay. Click here to view the full datasheet for ab6046. 10 µl trial size available.
Regulation of Microtubule Dynamics
|Post-translational modifications (PTMs)
||Acetylation on the K40 residue contributes to microtubule stability and cell motility. Deacetylation is linked to cell cycle progression and cancer.
||Acetylated α-tubulin (acetyl K40) antibody [EPR16772]
Acetylated α-tubulin antibody [6-11B- 1]
||Involved in cell differentiation and microtubule stabilization.
||Detyrosinated α-tubulin antibody
Human Detyrosinated α-tubulin peptide
||Occurs when glutamate side chains are formed on glutamate residues. Catalyzed by tubulin tyrosine ligase like (TTLL) enzymes.
||TTLL4 rabbit polyclonal antibody
TTLL6 mouse monoclonal antibody
||Contributes to microtubule stabilization. It is irreversible and acts on free tubulin as well as microtubules.
||ZM 449829 - Potent transglutaminase inhibitor
|Microtubule associated proteins (MAPs)
||Associates with microtubules and promote assembly and stabilization.
||MAP4 rabbit polyclonal antibody
Tau (phospho S396) rabbit monoclonal antibody
|Plus-end tracking proteins (+TIPs)
||+TIP recruitment results in microtubule stabilization, continued growth, and protrusion of the plus ends (migration).
||EB3 rabbit monoclonal antibody
Dynamitin mouse monoclonal antibody
CLASP1 rabbit monoclonal antibody
||Inhibits microtubule polymerization, block mitosis and induces cell death. Most agents bind the vinca or colchicine domain.
||Disrupts microtubules by promoting polymerization. This also inhibits mitosis and induces cell death.
Acetylation detection: Immunocytochemistry of formaldehyde-fixed HeLa cells stained with anti-alpha tubulin (acetyl K40) antibody [EPR16772] (ab179484). Positive control - Cell treatment with trichostatin A (ab120850), a potent deacetylase inhibitor. Nuclear DNA was labeled with DAPI (shown in blue). Click here to view the full datasheet for ab179484. 10 µl trial size available.
||Aided by ATP, they shuttle vesicular cargo away from the MTOC towards the plus-end of the microtubule.
||Kinesin 5A/B/C rabbit polyclonal antibody
Kinesin 5A rabbit polyclonal antibody
Kinesin 5C rabbit polyclonal antibody
||Aided by ATP, they shuttle vesicular cargo towards the minus end of microtubules.
||Dynein mouse monoclonal antibody
||Mainly associates with actin, but also interacts with tubulin for cargo exchange.
||Myosin VIIa rabbit polyclonal antibody
Non-muscle Myosin IIA rabbit monoclonal antibody
||Interacts with microtubules to maintain the integrity of chromatid spindles.
||HEC1 mouse monoclonal antibody [9G3]
Nuf2 rabbit monoclonal antibody
SPC24 rabbit monoclonal antibody
Mps1 mouse monoclonal antibody [N1] - BSA free
