NEB offers building blocks that can be used for linkage of the core benzylguanine (BG) and benzylcytosine (BC) moieties to activated esters, primary amines and thiol groups.
|BG-NH2||S9148||SNAP-tag substrate. Suitable for linkage to NHS esters and other activated carboxylic esters.||2 mg|
|BG-PEG-NH2||S9150||SNAP-tag substrate. PEG-linker gives superior flexibility. Particularly suited for immobilization on solid surfaces.||2 mg|
|BG-GLA-NHS||S9151||SNAP-tag substrate. Activated as NHS ester. Reacts with primary amines.||2 mg|
|BG-Maleimide||S9153||SNAP-tag substrate. Activated as maleimide. Reacts with thiols.||2 mg|
|BC-NH2||S9236||CLIP-tag substrate. Suitable for linkage to NHS esters and other activated carboxylic esters.||2 mg|
