Tubulysin H is a highly cytotoxic anti-microtubule toxin (anti-microtubule toxins) that is synthesized as an ADC cytotoxin (ADC Cytotoxin). Tubulysin H can be isolated from the myxobacteria Archangium geophyra and Angiococcus disciformis. Tubulysin H displays extremely potent cytotoxic activity in mammalian cells, including multidrug-resistant cell lines, with IC₅₀ values in the low nanomolar range. Tubulysin H inhibits microtubule/tubulin polymerization and leads to cell cycle arrest and apoptosis.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
