Product Information
The Nano-CaptureLigand® mouse IgG2b captures and immobilizes mouse IgG2b antibodies and Fc-fragments to avidin/streptavidin coated surfaces used in BLI, SPR, and ELISA assays. It consists of a biotinylated Nanobody that specifically binds to mouse IgG2b antibodies with high affinity and in a site-directed manner.
| Description | The next level of antibody immobilization to BLI and SPR biosensors:
• Gentle, site-directed and Fc-specific immobilization of mouse IgG2b antibodies and Fc-fragments to streptavidin coated biosensors without biotinylation of the antibody • Compatible to surface plasmon resonance (SPR) and biolayer interferometry (BLI) assays (e.g. FortéBio Octet® systems) • High affinity for stable baseline without significant dissociation • >10x regeneration for multiple reuse • High specificity enables mouse IgG2b antibody discovery and screening in crude liquids like hybridoma supernatant, serum, and plasma samples |
