Biological Activity

Description

Methyl methanesulfonate (MMS), a DNA alkylating agent, modifies both guanine (to 7-methylguanine) and adenine (to 3-methlyladenine) to cause base mispairing and replication blocks, respectively.

Targets

DNA alkylator ^[1]

In vitro
In vitro	Methyl methanesulfonate(MMS) is used for DNA damaging agent to induce mutagenesis. The repair of MMS-induced heat-labile damage requires the base excision repair protein XRCC1, and is independent of Homologous recombination in both S.cerevisiae and mammalian cells. ^[2]
Cell Research	Cell lines	EM9 cells , irs1SF cell lines, V3-3 cell lines, AA8 cells
	Concentrations	1.5 μM
	Incubation Time	0.5 h
	Method	Flasks are inoculated with 4 × 10⁶ cells for 4 h prior to a 24 h treatment with hydroxyurea or etoposide, or 28 h prior to a 0.5 h treatment with MMS or MNNG. After treatment, the cells are released from the flask by trypsinization and then used for pulsed-field gel electrophoresis.

In Vivo
In vivo	Methyl methanesulfonate(MMS) , as a genotoxic compound, has DNA damage potential in multiple organs such as the liver, kidneys and bone marrow in mice, confirmed by the in vivo comet assay.^[3]
Animal Research	Animal Models	Seven-week-old male Crli:CD1(ICR) mice
	Dosages	50mg/kg, 100mg/kg, 150 mg/kg
	Administration	i.p.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
