Nano-Traps
Affinity beads for immunoprecipitation
ChromoTek Nano-Traps are the benchmark in immunoprecipitation (IP) and allow fast and reliable one-step pulldowns of even low expressed proteins. They consist of Nanobodies coupled to beads and are ready-to-use.
Benefits:
- No heavy & light antibody chains
- Stringent washing conditions
- Low host cell protein background
- Very efficient pulldown, no protein in flow through
- High affinity to bind even proteins expressed at low levels
- Short incubation (30-60 min)
- Recombinantly expressed and validated
Nano-Traps can be applied in:
- IP, Co-IP
- Co-IP/MS
- On-bead assays
- ChIP/RIP analysis
- Split-Fluorescent Protein assays

Immunoprecipitation (IP) of a protein of interest (POI) by Nano-Traps (left) compared with conventional antibodies coupled to Protein A/G beads (right) analyzed by SDS-PAGE. When using Nano-Traps. the amount of immunoprecipitated POI is significantly higher and the background is reduced, in contrast to an IP conducted with a conventional antibody. Nano-Traps provide pure fractions of immunoprecipitated POI without contamination of heavy & light antibody chains. M: Marker, B: Bound.
Watch why GFP-Trap® gives the best results for immunoprecipitation
Low background, no extra bands & high specificity will improve your pulldown assay significantly. Alpaca Alice shows how it works.
