Tubulin is a major component of microtubules, the scaffolding of the eukaryotic cytoskeleton. It plays multiple roles in the maintenance of cell structure, intracellular vesicle and organelle transport, and cell division (mitosis and meiosis). Microtubules are formed by polymerization of alpha and beta tubulin isotypes, and the addition of proteins referred to as microtubule-associated proteins (MAPs). It has a molecular weight of 50 kDa and is composed of a double β-sheet core, enclosed within α-helices. Beta tubulin is a highly conserved, negatively charged protein, which has made it a popular target for anti-cancer drugs, aimed at disrupting microtubule dynamics and cell division. Anti-beta tubulin antibodies are commonly used as loading controls for immunoblotting to verify that uniform quantities of protein have been loaded across wells.

Figure 1. ELISA Dose Response curve using PtX™ Mouse Anti-Beta Tubulin (S11B) to detect coated Recombinant Human Tubulin beta chain Antigen at 0.25 ng/µl and increasing concentrations of antibody. Experiments were performed in triplicate, with error bars representing standard deviation (SD).

Figure 2. Western blot of decreasing amounts of recombinant Human beta chain antigen (50-70 kDa) detected with PtX™ Mouse Anti-Beta Tubulin (S11B) Antibody at 1: 10 000 and detected with a HRP conjugated anti-mouse secondary antibody at 1: 10 000.

Figure 3. Immunocytochemistry: HeLa cells were plated at 200 000 cells/ well in 6-well plates on coverslips and allowed to adhere. Following fixation and blocking, cells were incubated with 1:200 dilution of Cape Biologix PtXTM Mouse Anti-β-Tubulin primary antibody (Cat# CBT_A0041), and 1:300 dilution of a commercial Anti-Mouse Alexa Fluor® 488 conjugated commercial secondary antibody. Images were taken on a Zeiss LSM780 with ELYRA PS1 platform confocal microscope (20X) at the Stellenbosch University CAF unit. Thank you to Prof Georgia Schafer (ICGEB) for kindly donating the HeLa cells and Mrs Lize Engelbrecht for her outstanding assistance.

PtX™ | Plant-Based Expression

The biotechnology behind the development and manufacture of this product, transient plant-based expression, effectively turns Nicotiana benthamiana plants into single-use, biodegradable bioreactors. Infiltrating this plant species with Agrobacterium tumefaciens cells, transformed with our proprietary plant expression vectors, allows rapid production of a wide variety of recombinant proteins. Plants are harvested and proteins extracted by various stages of filtration, clarification, purification, and polishing – resulting in a highly functional final product.
