应用

甲磺酸乙酯已用于诱导小鼠胚胎成纤维细胞、酵母人胚肾细胞系和人淋巴细胞中的突变。

生化/生理作用

甲磺酸乙酯是一种DNA乙基化剂，对植物和动物具有致突变性，并在哺乳动物中具有致癌性。它已被用作DNA修复过程研究中的一种模范的烷化剂。EMS可诱导鸟嘌呤-胞嘧啶（G/C）碱基被取代为腺嘌呤-胸腺嘧啶（A/T）。EMS还可在基因组中产生点突变和单核苷酸多态性。MES是一种潜在的化学致突变剂，用于在水稻、小麦和拟南芥中诱导突变。

  1. 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.

  2. 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.

  3. I have heard that I need to use sodium thiosulfate with Product M0880, Ethyl methanesulfonate (EMS), but I’m 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.

  4. 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.

  5. I received a liquid. What is Product M0880, Ethyl methanesulfonate (EMS), dissolved in?

    It’s actually not dissolved in anything. Pure EMS is itself a liquid at room temperature; that is, the melting point is below room temperature.

  6. How does Product M0880, Ethyl methanesulfonate (EMS), compare to Product 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.

  7. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page. You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers.
