Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.
The Life Science industry has been in the grips of a reproducibility crisis for a number of years. Abcam is leading the way in addressing the problem with our range of recombinant monoclonal antibodies and knockout edited cell lines for gold-standard validation.
One factor contributing to the crisis is the use of antibodies that are not suitable. This can lead to misleading results and the use of incorrect data informing project assumptions and direction. To help address this challenge, we have introduced an application and species grid on our primary antibody datasheets to make it easy to simplify identification of the right antibody for your needs.

Target
-
Function
Regulatory subunit of the calcium-regulated non-lysosomal thiol-protease which catalyzes limited proteolysis of substrates involved in cytoskeletal remodeling and signal transduction. -
Sequence similarities
Contains 5 EF-hand domains. -
Domain
The contact of the 5th EF-hand domain from each monomer allows the formation of the homodimer and also appears to mediate the contact between the large catalytic subunit and small regulatory subunit for the formation of the heterodimer.
EF-hand domains are paired. EF-hand 1 is paired with EF-hand 2 and EF-hand 3 is paired with EF-hand 4. The fifth EF-hand domain, left unpaired, does not bind the calcium but is responsible of the dimerization by EF-embrace. The first four EF-hand domains bind calcium, however it is not sure if the binding of EF-hand 4 to calcium is physiologically relevant. -
Cellular localization
Cytoplasm. Cell membrane. Translocates to the plasma membrane upon calcium binding. - Information by UniProt

Western blot - Anti-Calpain small subunit 1 antibody [EPR3323] (ab92356)All lanes : Anti-Calpain small subunit 1 antibody [EPR3323] (ab92356) at 1/1000 dilution
Lane 1 : Wild-type HAP1 whole cell lysate
Lane 2 : CAPNS1 (Calpain small subunit 1) knockout HAP1 whole cell lysate
Lane 3 : HepG2 whole cell lysate
Lane 4 : HeLa whole cell lysate
Lysates/proteins at 40 µg per lane.
Predicted band size: 28 kDaLanes 1 - 4: Merged signal (red and green). Green - ab92356 observed at 82 kDa. Red - loading control, ab9484, observed at 37 kDa.
ab92356 was shown to specifically react with Calpain 1 in wild-type HAP1 cells as signal was lost in CAPNS1 (Calpain small subunit 1) knockout cells. Wild-type and CAPNS1 (Calpain small subunit 1) knockout samples were subjected to SDS-PAGE. ab92356 and ab9484 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.
