|2-Iminothiolane hydrochloride (Traut's Reagent) is a useful reagent for converting primary amine functional groups into free sulfhydryl groups. Traut's reagent (2-IT) is a simple water soluble, ringed molecule that completes this primary amine (-NH2) to sulfhydryl (-SH) conversion reaction in a one-step procedure in the pH range of 7 to 10. Once modification of a protein molecule with 2-Iminothiolane is complete, free amine groups will have been irreversibly converted to a sulfhydryl group with a four atom chain and without significant disruption of the original amine groups protonation state. |
After incorporation of the Traut's free sulfhydryl into a protein or otherwise, this -SH group makes for a very useful handle for further modification, such as selectively reacting this modified protein with a SMCC or BMPS containing conjugates, creating a permanent bond between two proteins. A 2-Iminothiolane modified protein or peptide could also be used to create a reversible link with an SPDP containing conjugate.
