Labeling Reagents

MSD^® SULFO-TAG or MSD TAG labels can be ordered with the purchase of MULTI-ARRAY^® or MULTI-SPOT^® plates. There is no charge for labeling reagents supplied with US, Canadian, and European orders. We supply both labeling reagents with an NHS Ester functional group for ease in labeling molecules more than 10 kDa with primary amines (usually external lysine residues or N-termini). The table lists the SULFO-TAG™ and TAG reagents.

Available labeling reagents:

Product	Quantity	Catalog Number
MSD SULFO-TAG	150 nMoles	R91AN-1
MSD SULFO-TAG	500 nMoles	R91AN-2
MSD TAG	150 nMoles	R91BN-1
MSD TAG	500 nMoles	R91BN-2

For alternative functional groups or quantities, please contact customer service.
