Schematic representation of anti-mouse IgG2a Nano-Secondary binding to its target. Mouse IgG2a primary antibody (grey) is bound with two identical monoclonal mouse IgG2a Fc- specific Nanobody molecules (green). In total, 4 fluorophores (red stars) label the mouse IgG2a primary antibody.
Dot-blot assay demonstrates that anti-mouse IgG2a Nano-Secondary is subclass-specific and does not cross-react with other mouse IgG subclasses including IgG1, IgG2b, IgG2c and IgG3.
The alpaca anti-mouse IgG2a Fc-specific recombinant VHH [CTK0114]
has a very high affinity (KD <10 pM) for mouse IgG2a primary antibody.
Immunofluorescence analysis of Hela cells stained with mouse IgG2a anti-Tubulin antibody (66240-1-Ig) and Nano-Secondary® alpaca anti-mouse IgG2a, recombinant VHH, CoraLite® Plus 647 (magenta). Nuclei were stained with DAPI (blue). Images were recorded at the Core Facility Bioimaging at the Biomedical Center, LMU Munich.
Flow cytometry analysis of 1X10^6 human peripheral blood mononuclear cells (PBMCs) stained with anti-human CD3 (clone OKT3, 65133-1-Ig) and Nano-Secondary® alpaca anti-mouse IgG2a, recombinant VHH, CoraLite® Plus 647.
