Product Information

Spot-Trap® Agarose is an affinity bead for immunoprecipitation (IP) of Spot-tagged proteins It comprises an anti-Spot-Tag® VHH/ Nanobody coupled to agarose beads.

DescriptionImmunoprecipitation of Spot-tagged proteins and their interacting factors with anti-Spot Nanobody conjugated to agarose beads.

• No contaminating heavy and light antibody chains

• Ready-to-use

• Recombinantly expressed without batch-to-batch variation

• Well-characterized and validated

• High stability allows for stringent washing

• Extraordinary low background compared to other affinity resins

• Short incubation time of 30-60 minutes
