Thermo Scientific Pierce Traut's Reagent (2-iminothiolane) is a small thiolation compound that reacts with primary amines (e.g., lysine side chains) to add a small spacer arm (8.1 angstroms) terminated by a free sulfhydryl group.

Features of Thermo Scientific Pierce Traut's Reagent (2-iminothiolane):

Simple—one-step conversion of amines to sulfhydryls
Specific—selective and spontaneous modification of primary amines at pH 7-10
• Preserves positive charge to maintain protein solubility

Traut's Reagent (2-iminothiolane or 2-IT) is a cyclic thioimidate compound for thiolation (sulfhydryl addition). Traut's Reagent reacts with primary amines (—NH2) to introduce sulfhydryl (—SH) groups while maintaining charge properties similar to the original amino group. Once added, sulfhydryl groups can be specifically targeted for reaction in a variety of useful labeling, crosslinking and immobilization procedures.

Flexible—incorporates a five-atom spacer arm to reduce steric hindrance
Soluble—preserves the original positive charge to preserve protein solubility

Frequently asked questions (FAQs)

How long and at what temperature can the Pierce Traut's Reagent (2-iminothiolane) (Cat. No. 26101) be stored in acidic solution devoid of primary amines?

We do not recommend storing the Traut’s Reagent in solution. This reagent is more stable in solution than others crosslinkers because hydrolysis takes place at a slower rate. Yet, its hydrolysis will inevitably occur with time if it is in solution. Therefore, to ensure a better crosslinking efficiency, we recommend preparing a fresh solution each time and storing the Traut's reagent as a powder at 4°C. Unfortunately, we do not have stability data of this reagent in a solution.
