Applications
Show applications key
Our Abpromise guarantee covers the use of ab28239 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
WB
Application notes
WB: 1/1000 when using colorimetric substrates such as BCIP/NBT, and 1/5000 for chemiluminescent substrates. Detects bands of approximately 30kDa and 28kDA (predicted molecular weight: 30 kDa). Calpain S1 is quickly degraded, and samples must be lysed in the presence of protease inhibiters to maintain latency. Dilution optimised using Chromogenic detection. Not yet tested in other applications. Optimal dilutions/concentrations should be determined by the end user.
Target
Relevance
Calpains are a ubiquitous, well-conserved family of calcium-dependent, cysteine proteases. Calpain families have been implicated in neurodegenerative processes, as their activation can be triggered by calcium influx and oxidative stress. Calpain I and II are heterodimeric with distinct large subunits associated with common small subunits, all of which are encoded by different genes. Calpain S1 is a small subunit common to both Calpain I and II and is associated with myotonic dystrophy.
Cellular localization
Cytoplasmic; translocates to the plasma membrane upon calcium binding

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections)-Calpain S1 antibody - Aminoterminal end domain VI(ab28239)
Ab28239 staining Human normal renal medulla. Staining is localized to the 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.
