Anti α tubulin mouse monoclonal antibody

Manufactured by Cell Signaling Technology
Sourced in United States

The Anti-α-tubulin mouse monoclonal antibody is a laboratory reagent used for the detection and localization of α-tubulin, a key structural component of the cytoskeleton. This antibody can be used in various immunodetection techniques, such as Western blotting, immunofluorescence, and immunohistochemistry, to study the distribution and dynamics of the cytoskeleton in cells and tissues.

Cells were lysed in ice-cold lysis buffer, and the lysates were centrifuged at 12,000 × g at 4°C for 20 min. The sample concentration was evaluated by a Pierce BCA Protein Assay kit (Thermo Fisher Scientific, MA, USA). Proteins were separated on SDS-polyacrylamide gels and then blotted onto membranes.[ 8 ] The blots were then reacted overnight at 4°C with the following primary antibodies: mouse anti-β-actin monoclonal antibody (A1978; Sigma-Aldrich), rabbit anti-CD137 monoclonal antibody (sc-398933; Santa Cruz Biotechnology, Inc.), mouse anti-HO-1 monoclonal antibody (ADI-OSA-110; Enzo Life Sciences, NY, USA), rabbit anti-FNDC5 monoclonal antibody (ab174833; Abcam, Cambridge, UK), goat anti-PGC1α polyclonal antibody (ab106814; Abcam), rabbit anti-PR domain containing 16 (PRDM16) polyclonal antibody (ab106410; Abcam), rabbit antiuncoupling protein 1 (UCP1) polyclonal antibody (ab10983; Abcam), and mouse anti-α-tubulin monoclonal antibody (#3873; Cell Signaling Technology, Danvers, MA, USA). Subsequently, the blot membranes were reacted with horseradish peroxidase-labeled secondary antibody for 1 h and further analyzed using enhanced chemiluminescence reagents (Pierce).

Cells were plated on glass coverslips in a 12-well plate and was treated with 10 nM paclitaxel, or the same amount of DMSO, for 12 h after cell adherence. All groups were run in triplicate. The cells in each well were fixed with 4% paraformaldehyde (Sigma, USA) for 20 min, permeabilized in 0.3% Triton X-100 (Thermo Fisher, USA) for 10 min, blocked with 5% serum for 1-2 h, and then probed overnight at 4 ℃ with mouse monoclonal anti-α-tubulin antibody (Cell Signaling, 3873, 1:500). Next, the coverslips were washed, and the cells incubated with Alexa 488-conjugated goat anti-mouse secondary antibody (Thermo Fisher, A32723, 1:500) for 1 h at room temperature. Nuclei were then labeled with DAPI (Thermo Fisher, USA), and slides of different groups were observed with a confocal microscope (Leica, Germany).

MDA-MB231 cells were incubated with compounds for 6 h and 24 h to observe the cellular microtubule network and the mitotic spindles respectively. Thereafter, the cells were fixed and permeabilized as described in the past report [42 (link)]. After blocking nonspecific binding with 1 % donkey serum/PBS, the cells were incubated with the mouse monoclonal anti-α-tubulin antibody (Cell Signaling Technology) (1:1000 dilution) followed by the Alexa-488 conjugated anti-mouse IgG antibody (Invitrogen) (1:500 dilution). To visualized nuclei, the cells were incubated with Hoechst33342. For staining phospho-Histone H3, the fixed cells were treated with the rabbit monoclonal anti-phospho-Histone H3 (Ser10) antibody (Cell Signaling Technology) (1:1000 dilution) followed by the Alexa-594 conjugated anti rabbit IgG antibody (Invitrogen) (1:500 dilution). Cellular images were obtained with SP8 confocal microscopy (Leica).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
