Anti-Calpain S1 antibody - Aminoterminal end domain V (ab28237)

Immunocytochemistry/ Immunofluorescence - Calpain S1 antibody - Aminoterminal end domain V (ab28237)

ICC/IF image of ab28237 stained HeLa cells. The cells were 100% Methanol fixed (5 min) and then incubated in 1%BSA / 10% normal Goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab28237, 1µg/ml) overnight at +4ºC. The secondary antibody (green) was Alexa Fluor® 488 Goat anti-Rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Calpain S1 antibody - Aminoterminal end domain V (ab28237)

Ab28237 staining Human normal renal medulla. Staining is localized the nucleus and cytoplasm.
Left panel: with primary antibody at 1 ug/ml. Right panel: isotype control.
Sections were stained using an automated system DAKO Autostainer Plus , at room temperature. Sections were rehydrated and antigen retrieved with the Dako 3-in-1 AR buffer EDTA pH 9.0 in a DAKO PT Link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 minutes. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS), then incubated with primary antibody for 20 minutes, and detected with Dako Envision Flex amplification kit for 30 minutes. Colorimetric detection was completed with diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that for manual staining we recommend to optimize the primary antibody concentration and incubation time (overnight incubation), and amplification may be required.

Western blot - Calpain S1 antibody - Aminoterminal end domain V (ab28237)

Predicted band size : 30 kDa


Plasma membrane (Membrane) and cytoplasmic (Cytosol) fractions were prepared from HUVEC cells and immunoblotted with antibodies against the indicated proteins. HRP-conjugated secondary antibodies were used. Blots are representative of four independent experiments.
