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 50kDa 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.

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.
