Alpha-tubulin is a globular protein which forms heterodimers with beta-tubulin to produce microtubules, the cytoskeletal filaments found in eukaryotic cells. The amino acid sequence of alpha-tubulin is highly conserved across eukaryotes, and contains a GTP-binding domain, which is important for regulating the assembly and disassembly of microtubules. Alpha-tubulin plays a crucial role in cell division, intracellular transport, and the maintenance of cell shape and polarity. Mutations in the alpha-tubulin gene have been linked to various diseases, including developmental disorders and cancer. The study of alpha-tubulin and its interactions with other proteins has important implications for understanding the basic biology of cells and the development of new therapies for human diseases.

Figure 1. ELISA Dose Response curve using PtX™ Rabbit Anti-Alpha Tubulin Antibody from 0,0002– 8,0 ng/uL to detect 25 ng Alpha 1a Tubulin, His Tagged antigen. Experiments were performed in triplicate, with error bars representing standard deviation (SD).

Figure 2. Western blot of decreasing amounts of HeLa Cell Lysate containing Alpha Tubulin (50 kDa) detected with PtX™ Rabbit Anti-Alpha Tubulin (F2C) at 1: 5 000 and an HRP conjugated anti-Rabbit secondary antibody at 1:30 000.

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 PtX™ Rabbit Anti-Alpha-Tubulin primary antibody (Cat# CBT_A0057), and 1:300 dilution of a commercial Anti-Rabbit 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.
