Product Introduction

Bioactivity

Description	Ansamitocin p-3 (Maytansinol isobutyrate) is an inhibitor of microtubule with IC50 of 3.4 μM for tubulin polymerization.
In vitro	Ansamitocin p-3 inhibits the proliferation in a concentration-dependent manner with IC50s of 20, 50, 140, and 150 pM for MCF-7, HeLa, EMT-6/AR1, and MDA-MB-231 cells in culture, respectively. Ansamitocin P3 binds to purified tubulin (Kd = 1.3 µM)[1].
Synonyms	NSC292222, Maytansinol isobutyrate, Antibiotic C 15003P3

For example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments

A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent

DMSO+30% PEG300+5% Tween 80+60% Saline/PBS/ddH₂O. So your working solution concentration is 2 mg/mL。

Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSO TargetMol | reagent

(mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.

Preparation method for in vivo formula: Take 50 μL DMSO TargetMol | reagent

main solution, add 300 μLPEG300 TargetMol | reagent

mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLSaline/PBS/ddH₂O TargetMol | reagent

mix well and clarify

For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.

All types of co-solvents required for the protocol, such asDMSO, PEG300/ PEG400, Tween 80, SBE-β-CD, corn oil are available for purchase on the TargetMol website with a simple click.
