Immunocytochemistry/ Immunofluorescence - Anti-Cathepsin L/V/K/H antibody [EPR8011] (AB133641)
Unpurified ab133641 staining Cathepsin L in Human HepaRG cell by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with formaldehyde, permeabilized with 0.1% Triton X-100 and blocked with 1% milk for 30 minutes at room temperature. Samples were incubated with primary antibody (1/1000) for 30 minutes. An Alexa Fluor® 488-conjugated Donkey anti-rabbit IgG polyclonal (1/400) was used as the secondary antibody.

We have systematically measured KD (the equilibrium dissociation constant between the antibody and its antigen), of more than 840 recombinant antibodies to assess not only their individual KD values but also to see the average affinity of antibody. Based on the comparison with published literature values for mouse monoclonal antibodies, Recombinant antibodies appear to be on average 1-2 order of magnitude higher affinity.

Shipping conditions update: ambient shipping
This product will be delivered at ambient temperature instead of chilled – this is by design. Extensive stability testing confirmed that our products are suitable for shipment under ambient conditions and maintain expected quality.
Why the change?
It’s part of our commitment to more sustainable packaging solutions, with ambient deliveries using eco-friendly materials such as recyclable cardboard instead of polystyrene.
What you need to know
- Ambient shipments come clearly marked on the delivery note.
- No ice will be included in ambient shipments, but mixed orders (ambient and cold-chain items) will still arrive with ice packs to protect temperature-sensitive products.
- Warranty coverage remains fully valid, aligned with our validated shipping method.
- Please store the product as per the datasheet instructions upon receipt.

Biological function summary
Cathepsins regulate cellular homeostasis and modulate various physiological processes. These proteases perform their functions within the lysosomal compartment although they can also participate in extracellular matrix remodeling and other non-lysosomal roles. Cathepsin K for example is part of the cathepsin protein family and aids in degrading collagen therefore playing a pivotal role in bone turnover and resorption. Cathepsins can act independently or in some cases are part of larger enzyme complexes enhancing their proteolytic activity to handle different substrates driven by the physiological demand.
Pathways
Cathepsins key in the lysosomal degradation pathway and influence other signaling cascades like the apoptotic pathway. The regulation of these pathways often involves interactions with other proteins such as pro-apoptotic members of the Bcl-2 family facilitating cell death under certain conditions. Cathepsin L contributes to the antigen processing pathway linking it to the immune response. Cathepsin K on the other hand acts closely with structural proteins like collagen in the bone metabolism pathway highlighting its significance in skeletal development and maintenance.
