Thiol kits

If your biomolecule does not have a free thiol group, it will require activation to generate a free thiol group prior to conjugation with the maleimide label:

1. Protein Thiolation kit

Designed to facilitate the conjugation of proteins to our maleimide-activated labels. Simply add your protein solution to the lyophilized thiolation reagents to activate your protein. These kits are designed to activate 2mg or 5mg of your protein. Each thiolation kit is also supplied with a thiolation detection kit provided as a positive test for protein thiolation, giving you the option to confirm the chemistry is working.

2. Thiol quantification kit

The thiol quantification assay kit allows you to quantify the amount of thiol/sulfhydryl (-SH) groups in samples of thiolated proteins or antibodies. Quantifying the number of free thiols in a sample can be useful in a number of applications and allows for a more controlled conjugation reaction. The assay is in a convenient 96-well plate format and contains all the necessary reagents required.
