The DSB-X™ Biotin Protein Labeling Kit contains reagents required for five protein conjugates of 0.5-3 mg each. DSB-X™ biotin is a derivative of desthiobiotin, a stable biotin precursor. DSB-X™ biotin utilizes a seven-atom spacer to increase the available of the DSB-X™ biotin conjugate to bind in the deep biotin-binding pocket of streptpavidin or avidin. Whereas harsh chaotropic agents and low pH are required to dissociate a biotin complex from avidin or steptavidin, binding can be reversed by adding excess D-desthiobiotin or natural D—biotin at neutral pH and at room temperature.
