Applications: acyl-RAC protein assays; Site-specific protein immobilization; Protein purification.

Description:

High capacity thiol capture,S3^TM Beads are one of Nanocs reactive agarose beads that can be used for reversible immobilization of biomolecules containing free thiol groups. S3^TM  thiol capture beads contain reactive pyridyl disulfide bonds that can react easily with free thiol groups under mild conditions. Reaction between thiol and pyridyl disulfide results a reversible dithio bond that can be cleaved by common dithio reducing agents such as DTT or TCEP. Compared to other thiol reactive beads, Nanocs S3^TM Beads have exceptionally high thiol capture capacity; Density of thiol reactive groups on S3 beads is 20-30 times more over conventional thiol activated agarose beads. S3 beads can be used in many applications, such as acyl-RAC protein assays; Site-specific protein immobilizations;  Protein purification, digestion and analysis. S3 beads are ideal replacements for commonly used activated Thiol-Sepharose 4B or Thiopropyl Sepharose 6B from GE.
