Which beads should I use for my immunoprecipitation?

ChromoTek's Nano-Traps are optimized for the immunoprecipitation (IP) of proteins and their interacting factors. Nano-Traps comprise of a Nanobody/ VHH conjugated to beads. For 3 Nano-Traps, e.g. GFP-Trap®RFP-Trap®, and Spot-Trap®, we offer different types of beads:

  • Agarose beads
  • Magnetic Agarose beads
  • Dynabeads™

Immunoprecipitation with GFP-Trap.
I: Input, FT: Flow-Through, B: Bound

Based on the properties of the different beads (see table), we recommend:

  • Agarose beads for very low background and high binding capacity IP
  • Magnetic Agarose beads for magnetic separation and high binding capacity IP
  • Dynabeads for IP of very large proteins/complexes

What GFP-Trap should I use for my immunoprecipitation?

ChromoTek GFP-Trap® is optimized for the immunoprecipitation of GFP-tagged proteins and their interacting factors.

The GFP-Trap consists of the ChromoTek anti-GFP Nanobody/ VHH that is coupled to 3 different types of beads or is immobilized in a 96 multiwell plate:

  • Agarose beads
  • Magnetic Agarose beads
  • Dynabeads™
  • 96 Multiwell Plate

Immunoprecipitation with GFP-Trap.
I: Input, FT: Flow-Through, B: Bound

Based on the properties of the different matrices (see table), we recommend:

GFP-Trap Dynabeads: Most cited GFP-Nanobody conjugated to Dynabeads

GFP-Trap® Dynabeads is optimized for the immunoprecipitation (IP) of large GFP-tagged proteins and for Co-IP of protein complexes. It consists of ChromoTek’s established anti-GFP Nanobody conjugated to Dynabeads™. Hence, also GFP-Trap Dynabeads has the very high affinity of 1 pM like GFP-Trap Agarose and Magnetic Agarose.
