Abcam has not and does not intend to apply for the REACH Authorisation of customers' uses of products that contain European Authorisation list (Annex XIV) substances.
It is the responsibility of our customers to check the necessity of application of REACH Authorisation, and any other relevant authorisations, for their intended uses.
Lysate preparation: Our lysates are made using RIPA buffer to which we add a protease inhibitor cocktail and phosphatase inhibitor cocktail (ratio: 300:100:10). This means that the protein of interest is denatured. If you require a native form of the protein please use the live cell version. Please refer to our lysis protocol for further details on how our lysates are prepared.
User storage instructions: Lyophilizate may be stored at 4°C. After reconstitution, store at -20°C for short-term storage or -80°C for long-term storage.
This product is subject to limited use licenses from The Broad Institute and ERS Genomics Limited, and is developed with patented technology. For full details of the limited use licenses and relevant patents please refer to our limited use license and patent pages.

- Activity summary
Cathepsin L also known as CTSL is a protease enzyme that has a mass of approximately 29-30 kDa. It originates from the peptidase C1 family and undergoes activation in acidic environments. This protein carries out proteolytic processes by breaking down proteins through cleaving peptide bonds. Cathepsin L has various forms including MEP (a common alternate name) and MEP L and it expresses itself in organs such as the liver kidney and spleen as well as in tumors and immune cells. It has a significant functional role in lysosomes where it degrades proteins.
- Biological function summary
Cathepsin L links to cellular homeostasis and extracellular matrix remodeling. It often acts in protein turnover and antigen processing within endolysosomal compartments making it essential for major histocompatibility complex class II presentation. Cathepsin L forms complexes in certain conditions playing roles in interacting and modifying other proteins. It controls processes essential for cell survival differentiation and apoptosis.
- Pathways
Cathepsin L plays significant roles in pathways like apoptosis and autophagy. It coordinates with other proteases and proteins such as cathepsin B and cathepsin S to regulate cell death and survival. In apoptosis cathepsin L mediates the breakdown of cellular components working alongside caspases. Its interaction with autophagy involves degradation of long-lived proteins highlighting its role in recycling amino acids during stress conditions.
- Associated diseases and disorders
Cathepsin L connects strongly to cancer and fibrotic diseases. It contributes to tumor progression and metastasis due to its ability to degrade the extracellular matrix and enable cancer cell invasion. In fibrosis cathepsin L modulates the turnover of fibrous tissue linking to the development of lung fibrotic diseases. Proteins like collagenases work in concert with cathepsin L during these pathological processes to remodel tissues underlining its implication in disease states.

Western blot - Human CTSL (Cathepsin L/MEP) knockout HEK-293T cell lysate (ab257213)
False colour image of Western blot: anti CTSL antibody staining at 1/200 dilution, shown in green; Rabbit anti-alpha Tubulin antibody [EP1332Y] (Anti-alpha Tubulin antibody [EP1332Y] - Microtubule Marker ab52866) loading control staining at 1/20000 dilution, shown in red. A band was observed at 25 kDa in wild-type HEK-293T cell lysates with no signal observed at this size in anti CTSL antibody knockout cell line Human CTSL (Cathepsin L/MEP) knockout HEK-293T cell line ab266521 (knockout cell lysate ab257213). To generate this image, wild-type and anti CTSL antibody knockout HEK-293T cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in fluorescent western blot (TBS-based) blocking solution before incubation with primary antibodies overnight at 4°C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Mouse IgG H&L (IRDye® 800CW) preabsorbed (Goat anti-Mouse IgG H&L (IRDye® 800CW) preadsorbed ab216772) and Goat anti-Rabbit IgG H&L (IRDye® 680RD) preabsorbed (Goat Anti-Rabbit IgG H&L (IRDye® 680RD) preadsorbed ab216777) at 1/20000 dilution.
