General description

γ-Tubulin (48kDa) is a ubiquitous and highly conserved protein within the microtubule organizing centers (MTOCs) in eukaryotic cells.[71] γ-Tubulin is mapped to human chromosome 17q21.2 and codes for a member of the tubulin family.[15][16] Human TUBG1 transcript is widely expressed in preimplantation embryos and brain.[21]
Monoclonal Anti-γ-Tubulin (mouse IgG1 isotype) is derived from the GTU-88 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from an immunized mouse.


Monoclonal Anti-γ-Tubulin recognizes an epitope located in the N-terminal amino acids of γ-tubulin (48 kDa). Cross reactivity has been observed with human, bovine, dog, hamster, rat, mouse, chicken, and Xenopus γ-tubulin.
The antibody recognizes an epitope located within the N-terminal region of γ-tubulin.


synthetic γ-tubulin peptide, conjugated to KLH


Monoclonal Anti-γ-Tubulin antibody has been used in western blotting,[73][74][59] indirect immunofluorescence (IF)[76] and immunofluorescence staining.[77]
Monoclonal Anti-γ-Tubulin is also suitable for use in immunochemical applications such as immunoblotting, immunocytochemical staining of cultured cells and in ELISA.
Monoclonal Anti-gamma-Tubulin is suitable for use in immunochemical applications such as immunoblotting, immunocytochemical staining of cultured cells, and in ELISA.

Biochem/physiol Actions

γ-Tubulin nucleates microtubule assembly throughout the mammalian cell cycle in vivo.[17] γ-Tubulin binds microtubule minus ends and is responsible for mediating the link between microtubules and the centrosome. It functions as the microtubule nucleator at the MTOC.[72] It binds to the β-tubulin half of the tubulin molecule, thus establishing the polarity of a microtubule, leaving the α-tubulin half exposed at the plus end. γ-Tubulin abundance is less than 1% of the level of either α- or β-tubulin. Overexpression of γ-tubulin is observed in lung cancer.[69] The expression levels of γ-tubulin can be considered as an important prognostic indicator for patients with astrocytomas.[23]

Physical form

The product is provided as ascites fluid with 15 mM sodium azide as a preservative.

Storage and Stability

For continuous use, store at 2-8 °C for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing, or storage in "frostfree" freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use.
