Frequently Asked Questions

Which document(s) contains shelf-life or expiration date information for a given product?
If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.
How do I get lot-specific information or a Certificate of Analysis?
The lot specific COA document can be found by entering the lot number above under the "Documents" section.
I have heard that I need to use sodium thiosulfate with Product M0880, Ethyl methanesulfonate (EMS), but Im not sure how. Can you tell me?
EMS is a mutagen. After treating cells with EMS, the mutagenesis reaction may be stopped by adding the appropriate volume of a 5% sodium thiosulfate solution.The use of a 10% sodium thiosulfate solution with 1% TWEEN 20 has been used to clean surfaces and items such as pipettes that have been contaminated with EMS in mineral oil.
Is Product M0880, Ethyl methanesulfonate (EMS), sterile?
It is not necessarily sterile. For those applications that require a sterile EMS solution, the EMS should be added to the appropriate buffer or medium. The buffer or medium should then be sterile-filtered.
I received a liquid. What is Product M0880, Ethyl methanesulfonate (EMS), dissolved in?
Its actually not dissolved in anything. Pure EMS is itself a liquid at room temperature; that is, the melting point is below room temperature.
How does Product M0880, Ethyl methanesulfonate (EMS), compare toProduct 64292, which is the same chemical?
Product No. 64292 is tested for purity by a titration assay. Although M0880 is likely to be of similar quality, there is no purity assay performed on it.
How do I find price and availability?
