Proteintech anti-IgG VHH beads

Click2Contact

While Protein A and G remain the most common choices for antibody capture, their broad and unspecific Fc binding and potential for leaching from beads can compromise specificity and lead to interfering background in sensitive assays. Optimised for targeted precision and clean results, Proteintech’s VHH-based beads are designed to redefine specificity and purity in immunoprecipitation, offering species-specific IgG binding and no Protein A or G contamination.

The company’s anti-rabbit/anti-mouse VHH beads are conjugated with a mix of three high-affinity VHHs (Nanobodies) targeting rabbit IgG, mouse IgG1, and mouse kappa light chains. This combination enables broad compatibility with the most commonly used rabbit and mouse antibodies.

Whether the user is performing routine IPs across various antibody subtypes or working with antibodies of unknown isotype, the beads offer a powerful alternative to Protein A or Protein G, delivering clean, efficient pulldowns with consistent performance.
