Anti-Desmin antibody (ab15200)

Immunohistochemistry (Paraffin-embedded sections) - Desmin antibody (ab15200)

Ab15200 positively staining desmin in formaldehyde fixed mouse heart tissue (1/200). Ab15200 was used in conjunction with goat anti rabbit (biotin).

The reviewer reported no difference in the quality of staining obtained when enzymatic epitope unmasking was preformed.

Immunohistochemistry (Frozen sections) - Desmin antibody (ab15200)

ab15200 at a 1/200 dilution staining mouse aortic root tissue sections by Immunohistochemistry (Frozen sections). The tissue was paraformaldehyde fixed and blocked with 10% serum then incubated with antibody for 30 minutes. Bound antibody was detected using a biotinylated goat anti-rabbit antibody.

Immunocytochemistry/ Immunofluorescence - Desmin antibody (ab15200)

ab15200 staining rat differentiated skeletal muscle cells by ICC/IF.

Cultured differentiated skeletal muscle cells were harvested from Lewis rats, 2% paraformaldehyde treated for 15 min to fix the cells, and then permealized with Triton-X100 (0.1%) for 10 min. The cells were then incubated with ab15200 at 1/200 overnight at 4°C. The image was taken with a confocal laser scanning microscope and shows desmin expressing skeletal myocytes (green-cytoplasmic localization). Note that desmin forms short thickened filamentous structures in the cell cytoplasm, along with prominent spot-like cytoplasmic aggregates that are composed of densely packed filaments.

Anti-Desmin antibody (ab15200) at 1 µg/ml + Placenta (Human) Tissue Lysate - adult normal tissue (ab29745) at 10 µg

Secondary
Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution

Predicted band size : 52 kDa
Observed band size : 55 kDa (why is the actual band size different from the predicted?)
Additional bands at : 72 kDa (possible non-specific binding).

Immunocytochemistry/ Immunofluorescence - Desmin antibody (ab15200)

ab15200 staining Desmin in rat Smooth muscle cells from mesenteric artery by Immunocytochemistry/ Immunofluorescence. Cells were fixed with 4% paraformaldehyde in PSS for 4 min at 4°C and permeabilized with 0.3% Triton x100 before blocking with 2% BSA was done for 30 minutes at 20⁰C. Samples were incubated with primary antibody (1/300: in PSS with 2%BSA and 0.3% Triton X-100) for 14 hours at 4°C. An MFP 555-conjugated donkey polyclonal to rabbit IgG was used as secondary antibody at 1/400 dilution.
