• 

  Anti-mouse IgG1 Nano-Secondary: Well-defined and characterized immunostaining. Primary anti-mouse IgG1 antibody (grey) with 2X2 monoclonal mouse Fc- specific Nanobodies (green) bound. In total, 8 fluorophores (red stars) label the mouse IgG1 primary antibody.

• 

  Immunostaining with Alpaca anti-mouse IgG1 Alexa Fluor 647 Nano-Secondaries for FACS. Jurkat CD3+ and Jurkat CD3- cell lines were mixed and immunostained live with anti-CD3 mouse IgG1 + alpaca anti-mouse IgG1 VHH Alexa Fluor 647 (1:600). CD3- cells were pre-stained with Calcein. Two cell populations can be clearly distinguished on the dot-plot: Alexa Fluor 647-positive Calcein-negative cells and Alexa Fluor 647-negative Calcein-positive cells.

• 

  Multiplexed immunostaining of HeLa cells with 3 subclass-specific alpaca anti-mouse Nano-Secondaries. Grey: Mouse IgG1 anti-Vimentin + alpaca anti-mouse IgG1 VHH Alexa Fluor® 647. Green: Mouse IgG2b anti-Lamin + alpaca anti-mouse IgG2b VHH Alexa Fluor® 488. Red: Mouse IgG3 anti-MOT + alpaca anti-mouse IgG3 VHH Alexa Fluor® 568. Scale bar, 10 μm. Images were recorded at the Core Facility Bioimaging at the Biomedical Center, LMU Munich.

• 

  Western blot analysis of EGFP (EGFP-250, ChromoTek) added to HEK293T cell lysate. Detection with anti-GFP mouse IgG 1 antibody and alpaca anti-mouse IgG1 VHH Alexa Fluor® 647.

• 

  One-step staining (left) vs. sequential staining (right) of HeLa cells with anti-COX4 (mitochondria) mouse IgG1 monoclonal primary antibody + alpaca anti-mouse IgG1 VHH Alexa Fluor® 647 (magenta). Cell nuclei are stained with DAPI (blue). Scale bar, 20 μm.

• 

  The anti-mouse IgG1 Nano-Secondary is subclass-specific and does not cross-react with IgGs from other commonly used species (here rabbit) and with mouse IgG2b and IgG3 subclasses.

• 

  Multiplexed immunostaining of HeLa cells with 3 subclass-specific alpaca anti-mouse Nano-Secondaries. Grey: Mouse IgG1 anti-Vimentin + alpaca anti-mouse IgG1 VHH Alexa Fluor® 647. Green: Mouse IgG2b anti-Lamin + alpaca anti-mouse IgG2b VHH Alexa Fluor® 488. Red: Mouse IgG3 anti-MOT + alpaca anti-mouse IgG3 VHH Alexa Fluor® 568. Scale bar, 10 μm. Images were recorded at the Core Facility Bioimaging at the Biomedical Center, LMU Munich.

• 

  HeLa cells were immunostained with anti-Vimentin mouse IgG1 antibody and alpaca anti-mouse IgG1 VHH Alexa Fluor® 647 (grey). Nuclei were stained with DAPI, blue. Scale bar, 10 μm. Images were recorded at the Core Facility Bioimaging at the Biomedical Center, LMU Munich.

• 

  One-step immunostaining is the simultaneous incubation of mouse IgG1 primary antibody and anti-mouse IgG1 Nano-Secondary. This method reduces incubation and hands-on time. Simultaneous incubation also supports multiplexing, tissue penetration, and cell staining for flow cytometry.

• 

  Flow cytometry with anti-mouse Nano-Secondaries. Jurkat CD3+ and Jurkat CD3- cell lines were mixed and immunostained live with anti-CD3 mouse IgG1 and alpaca anti-mouse IgG1 VHH Alexa Fluor® 647 (1:600). Two cell populations can be clearly distinguished with a 2-log shift: CD3-positive cells (in green) and CD3-negative cells (in grey).
