MagVigen™ for Co-Immunoprecipitation

  • Smaller beads
  • Low nonspecific binding
  • Higher binding capacity (6x higher)
  • Highly biocompatible surfaces
  • Less steric hindrance and better accessibility to epitopes
  • Optimal surface chemistry
  • High throughput automation

MagVigen nanobeads plus sign interacting Protein A and Protein B molecules right arrow Protein A and Protein B bound with MagVigen beads dynamic interactions discovered between proteins using MagVigen co_ip

Figure 1. Dynamic interactions between Protein A and Protein B were detected by co-immunoprecipitation using MagVigen™ nanobeads. Such interactions were not seen using conventional magnetic beads.

big conventional magnetic beads

Figure 2. Conventioal magnetic beads may present more steric hindrance and unideal chemistry hence not capturing elusive molecular/protein interactions.


Figure 3. Two Lots of MagVigen™ Streptavidin (2mg/mL) and Dynabeads MyOne Streptavidin (10mg/mL) were used to capture 1µg of biotinylated mouse IgG. The amount of uncaptured biotinylated mouse IgG was determined by ELISA. The percentage of captured biotinylated mouse IgG was plotted. MagVigen™ beads showed an antibody binding capacity of 50µg/mg compared to 12µg/mg for Dynabeads.


Figure 4. Capture antibody conjugated MagVigen™ Streptavidin beads (20 µg), Dynabeads MyOne (30 µg) and Merck beads (30 µg) were used in ELISA assay following a standard protocol to detect HBV antigen HBsAg. Bead pellets were reconstituted in 100µl of PBS in the end and 5µl were used to develop color.
