Validation Data Gallery

• 

  Well-defined and characterized immunostaining: Primary anti-rabbit IgG antibody (grey) with 2 copies each of a rabbit Fab- and Fc-specific monoclonal Nanobodies (green) bound. In total, 8 fluorophores (red stars) label the primary rabbit IgG antibody.

• 

  HeLa cells stably expressing Tubulin-GFP at near-endogenous level were immunostained with rabbit anti-GFP PABG1 antibody and alpaca anti-rabbit IgG VHH Alexa Fluor? 647 (magenta). Nuclei were detected with H2B-RFP and RFP-Booster Atto594 (cyan). Scale bar, 10 μm. Images were recorded at the Core Facility Bioimaging at the Biomedical Center, LMU Munich.

• 

  Higher resolution with anti-rabbit IgG Nano-Secondaries compared to conventional secondary antibodies: Left: Formation of a small, precise complex of Nanobodies (green) & primary antibody (grey). Right: Formation of a large, arbitrary complex of multiple polyclonal secondaries (green) & primary rabbit antibody.

• 

  HeLa cells were immunostained with rabbit anti-Lamin B1 antibodies and alpaca anti-rabbit IgG VHH Alexa Fluor? 568 (1:1,000). Confocal and gated STED images were acquired with a Leica TCS SP8 STED 3X microscope, pulsed depletion with a 775 nm laser. Images were recorded at the Core Facility Bioimaging at the Biomedical Center, LMU Munich.

• 

  One-step immunostaining (top row) vs. sequential immunostaining (bottom row) of HeLa cells. Anti-β-Actin (left column) and anti-LaminB1 (right column) primary rabbit antibodies + secondary alpaca anti-rabbit IgG VHH Alexa Fluor? 647. Scale bar, 20 μm.

I used this secondary in an indirect flow cytometry experiment, staining for a phospho-protein. I found that this secondary resulted in a stronger signal when compared to my regular life scientific alexa fluor secondary antibody. I will be using these nanobodies from now on! The antibody was used at a dilution of 1:4000, 30m RT staining.
