ChromoTek Nano-CaptureLigand® mouse IgG2a, Fc-specific VHH, biotinylated

Validation Data Gallery

• 

  BLI binding kinetics of a mouse IgG2a anti-V5-tag antibody to a V5-tagged protein. A monoclonal mouse IgG2a anti-V5-tag antibody was immobilized using Nano-CaptureLigand mouse IgG2a, Fc-specific VHH, biotinylated on FortéBio Streptavidin (SA) Biosensors and assayed with different concentrations of a V5-tagged protein.

• 

  Immobilization of the Nano-CaptureLigand (green) on Biosensor (white) for biolayer interferometry (BLI) followed by capture of mouse IgG2a antibody (orange). The setup is ready for characterization of mouse IgG2a antibodies’ binding kinetics and affinity to substrate (red), mouse IgG2a antibody discovery and screening in crude liquids like hybridoma supernatant, serum, and plasma.

• 

  ELISA capture of mouse IgG2a antibody using Nano-CaptureLigand mouse IgG2a, Fc-specific VHH, biotinylated. 50 nM Nano-CaptureLigand mouse IgG2a, Fc-specific VHH, biotinylated was used for coating on an avidin-coated MaxiSorp plate. Mouse IgG2a antibody was titrated in a 1:2 dilution series and detected with an alkaline phosphatase-conjugated detection antibody.

• 

  Sandwich ELISA: Immobilization of the Nano-CaptureLigand on streptavidin coated microplates for ELISA. No biotinylation of the antibody is required.

Product Information

The Nano-CaptureLigand® mouse IgG2a captures and immobilizes mouse IgG2a 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 the mouse IgG2a subclass 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 IgG2a 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 IgG2a antibody discovery and screening in crude liquids like hybridoma supernatant, serum, and plasma samples
