PureCube Thiol Activated MagBeads

PureCube Thiol Activated MagBeads carry a dipyridyl disulphide functionality. Proteins can bind covalently via free cysteines, forming a disulfide bond, and releasing a 2-thiopyridone group. Because  of  the  nature  of  the  disulfide  bond,  the  coupled  proteins  can  also  be  eluted  using reducing agents such as DTT or beta-mercaptoethanol.

Different thiol containing proteins can be eluted by using a combination or concentration gradient of weaker (e.g. L-cysteine, reduced glutathione) and stronger (DTT or mercaptoethanol) reducing agents. PureCube Thiol  Activated MagBeads are delivered in lyophilized format to ensure product quality.

Thiol Activated MagBeads require 2,2‘-dipyridyl disulphide for activation, which is included in the product.

 

For irreversible coupling of thiol groups, see Maleimide Activated MagBeads.
