CaptureSelect™ Biotin Anti-IgG-CH1 Conjugate consists of a 14 kDa llama antibody fragment (affinity ligand) that specifically binds to the CH1 domain of all four human IgG subclasses. The affinity ligand is chemically conjugated to biotin via an appropriate spacer that retains the binding reactivity of the ligand when used in combination with streptavidin-based conjugates or streptavidin pre-coated surfaces.

The CaptureSelect™ Biotin Anti-IgG-CH1 Conjugate allows you to:

Detect, quantitate, and characterize all human IgG antibodies (subclasses 1 to 4) and Fab fragments thereof, independent of light chain type, and total IgG in human plasma and/or serum samples
Avoid cross-binding with other isotypes, such as IgA, IgM, IgD, and IgE, free light chains, or IgG from mouse sources or bovine sources such as FCS
Screen antibody-antigen interactions—biotin anti-IgG-CH1 forms a stable [low k(diss)] complex with human IgG antibodies through bivalent binding

Applications for CaptureSelect™ Biotin Anti-IgG-CH1 Conjugate include ELISA, Western blot, Gyrolab™-based immunoassays, and label-free detection platforms such as those based on surface plasmon resonance (Biacore™ and IBIS-MX96 systems) and bio-layer interferometry (ForteBio™ Octet™ systems).
