ChromoTek MBP-Trap Agarose beads

Validation Data Gallery

• 

  Immunoprecipitation of maltose binding protein (MBP) from E. coli cell extract. The Western blot shows the very high effectivity of the MBP-Trap: No MBP is left in Flow-Through lane.I: Input, FT: Flow-Through, B: Bound.

The ChromoTek MBP-Trap Agarose are affinity beads for IP of MBP-fusion proteins. They comprise MBP Nanobodies/ VHHs coupled to agarose beads.

Product Information

The ChromoTek MBP-Trap Agarose are affinity beads for IP of MBP-fusion proteins. They comprise MBP Nanobodies/ VHHs coupled to agarose beads.

• Description: Immunoprecipitation of MBP-fusion proteins and their interacting factors with anti-MBP Nanobody conjugated to beads.

  • Immunoprecipitation of low abundant MBP-fusion proteins

  • Significantly higher sensitivity than amylose resin and other affinity resins

  • No heavy & light antibody chains

  • Stable under harsh washing conditions

  • Suitable for downstream mass spec analysis

• Applications: IP, CoIP, ChIP, RIP
• Specificity/Target: Maltose-binding protein (MBP) of Escherichia coli
• Binding capacity: 45 μg (0.625 nmol) of recombinant MBP-tagged protein (~74.2 kDa) per 25 μL bead slurry

I successfully used these beads to capture recombinant MBP-tagged protein and perform in vitro phosphorylation assay with MBP-tagged protein on beads. Much lower background than other beads.

• Applications: Immunoprecipitation
• Cell Tissue Type: recombinant protein
