Product Information

Spot-Trap® Magnetic Agarose is an affinity reagent for immunoprecipitation (IP) of Spot-tagged proteins. It consists of an anti-Spot-Tag® VHH/ Nanobody that is coupled to magnetic agarose beads.

DescriptionThe Spot-Trap Magnetic Agarose Kit contains Spot-Trap Magnetic Agarose, lysis, wash, and elution buffers for efficient immunoprecipitation of Spot-tagged proteins and their interacting factors.

• No contaminating heavy and light antibody chains

• Ready-to-use

• Recombinantly expressed without batch-to-batch variation

• Extraordinary low background compared to other affinity resins

• Compatible with harsh buffer conditions

• Suitable for downstream mass spec analysis

• Short incubation time of 30-60 minutes
