S-Methyl methanethiosulfonate (MMTS) is commonly used to modify and block thiol groups in proteins. To achieve effective blocking of thiol groups with MMTS, the following ranges should be considered:
pH: Reactions with MMTS are typically performed in buffers with a pH range of 7-8.
Temperature: Blocking of Thiols can be carried out at room temperature (25 °C).
A literature search is encouraged to determine the best conditions for specific applications.
