Signal-Seeker PTM Detection Kits

The Signal-Seeker™ line of products have been developed to allow simple analysis of key regulatory protein modifications by specialists and non-specialists alike.


The comprehensive Signal-Seeker™ kits provide an affinity bead system to isolate and enrich modified proteins from any given cell or tissue lysate. The enriched protein population is then analyzed by standard western blot procedures using a primary antibody to the target protein.
