BLI binding kinetics of a monoclonal rabbit IgG anti-DYKDDDDK-tag antibody to a DYKDDDDK-tagged protein. A monoclonal rabbit IgG anti-DYKDDDDK-tag antibody was immobilized using Nano-CaptureLigand human IgG/rabbit IgG, Fc-specific VHH, biotinylated on FortéBio Streptavidin (SA) Biosensors and assayed with different concentrations of a DYKDDDDK-tagged protein.
ELISA capture of a rabbit IgG antibody using Nano-CaptureLigand human IgG/rabbit IgG, Fc-specific VHH, biotinylated. 50 nM Nano-CaptureLigand human IgG/rabbit IgG, Fc-specific VHH, biotinylated was used for coating on an avidin-coated MaxiSorp plate. Rabbit IgG antibody were titrated in a 1:2 dilution series and detected with an alkaline phosphatase-conjugated detection antibody.
BLI binding kinetics of a polyclonal rabbit IgG anti-GFP antibody to eGFP. A polyclonal rabbit IgG anti-GFP antibody (ChromoTek GFP antibody [PABG1]) was immobilized using Nano-CaptureLigand human IgG/rabbit IgG, Fc-specific VHH, biotinylated on FortéBio Streptavidin (SA) Biosensors and assayed with different concentrations of eGFP (ChromoTek EGFP, recombinant protein).
BLI binding kinetics of different human IgG antibodies. Different monoclonal human IgG antibodies were immobilized using Nano-CaptureLigand human IgG/rabbit IgG, Fc-specific VHH, biotinylated on FortéBio Streptavidin (SA) Biosensors. All four human IgG subclasses are stably captured by the Nano-CaptureLigand with negligible dissociation.
Immobilization of the Nano-CaptureLigand (green) on Biosensor (white) for biolayer interferometry (BLI) followed by capture of human IgG antibody (orange). The setup is ready for characterization of human IgG antibodies’ binding kinetics and affinity to substrate (red), human IgG antibody discovery and screening in crude liquids like hybridoma supernatant, serum, and plasma.
ELISA capture of human IgG1 lambda antibody using Nano-CaptureLigand human IgG/rabbit IgG, Fc-specific VHH, biotinylated. 50 nM Nano-CaptureLigand human IgG/rabbit IgG, Fc-specific VHH, biotinylated was used for coating on an avidin-coated MaxiSorp plate. Human IgG1 lambda 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. Coating of the streptavidin microplate with Nano-CaptureLigand (top left). Site-directed antibody immobilization via Nano-CaptureLigand (top right). Addition of sample including target (red, bottom left). Addition of detection and secondary antibody for read-out (bottom right).
