ab170190 - Mouse monoclonal IgG1 (Alexa Fluor® 488), is suitable for use as an isotype control to complement this secondary antibody.


  • ICC/IF image of ab7291 stained HeLa cells. The cells were 100% methanol fixed (5 min), permeabilized with 0.1% Triton X-100 for 5 minutes and then incubated in 1%BSA / 10% normal donkey serum / 0.3M glycine in 0.1% PBS-Tween for 1h to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab7291, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab150105 Alexa Fluor® 488 donkey anti-mouse IgG (H+L) used at 2µg/ml for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

    The negative control (inset) is a secondary-only assay to demonstrate low non-specific binding of the secondary antibody.

Immunocytochemistry/ Immunofluorescence
Excellent antibody. Used at 1:500 dilution in PBS-Triton X-100 (0.1%) overnight at 4 degrees. Used in conjunction with GFAP antibody (Ab80842). Stable fluorescence when mounted with Vectashield (inc DAPI).

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections)
This antibody works perfectly at a 1:500 dilution with SALL4 primary antibody (ab57577, mouse monoclonal). However, the intensity of this Donkey secondary antibody is weaker than that of the Goat secondary antibody (ab150113) at the same dilution. So that is why I gave it 4 stars.
