Western Blot Validated Immunofluorescence Validated Immunocytochemistry Validated

Application Notes

Applications Validated by Active Motif:
WB*: 1:500 - 1:2,500 dilution
ICC/IF: 1:1,000 - 1:10,000 dilution

*Note: many chromatin-bound proteins are not soluble in a low salt nuclear extract and fractionate to the pellet. Therefore, we recommend a High Salt / Sonication Protocol when preparing nuclear extracts for Western Blot.

alpha Tubulin antibody (mAb) - 100 µg (Cat. No. 39527)



alpha Tubulin mAb (Clone 5-B-1-2) tested by immunofluorescence.
Top: HeLa cells stained with alpha Tubulin mAb at 1:500 dilution (red). Middle: Same cells stained with DAPI (blue). Bottom: Both images merged. Staining was carried out using MAX Stain™ Immunofluorescence Tools.

alpha Tubulin mAb (Clone 5-B-1-2) tested by Western blot.
HeLa whole-cell extract (15 µg/lane) probed with alpha Tubulin mAb (1:5,000 dilution).


Microtubules of the eukaryotic cytoskeleton perform essential and diverse functions and are composed of a heterodimer of α-tubulin and β-tubulin. Alpha Tubulin expression is reduced in cells deficient in MeCP2, leading to conditions such as Rett syndrome and autistic-spectrum disorders.

Positive Control

Active Motif's HeLa whole-cell extract (Catalog No. 40050) can be used as a positive control for alpha Tubulin antibody (Clone 5-B-1-2).
