Description

Dolastatin 10 (DLS 10) is a potent antimitotic peptide that inhibits tubulin polymerization.

IC₅₀ & Target

Auristatin

In Vitro

Dolastatin 10 is a unique pentapeptide that isolated from the sea hare Dolabella auricularia. These in vitro data are quite comparable to those of Dolastatin 10 and Auristatin PE, each of which has GI₅₀ values of 10⁻⁵-10⁻⁶ μg/mL (10⁻²-10⁻³ nM) against a similar minipanel of human cell lines^[2]. The antibody-drug conjugate (ADC) comprises the anti-CD30 monoclonal antibody cAC10 conjugated to the cytotoxic agent monomethyl auristatin E (MMAE), a synthetic analog of the tubulin polymerization inhibitor Dolastatin 10^[3].

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.
