Western blot - Human CTSS knockout THP-1 cell line (AB275846)
False colour image of Western blot : Anti-Cathepsin S antibody [EPR5128] staining at 1/1000 dilution shown in green; Mouse anti-Alpha Tubulin [DM1A] (ab7291) loading control staining at 1/20000 dilution shown in red. In Western blot ab134157 was shown to bind specifically to Cathepsin S. A band was observed at 25 kDa in wild-type THP-1 cell lysates with no signal observed at this size in Ctss knockout cell line ab275846 (knockout cell lysate ab275820). To generate this image wild-type and Ctss knockout THP-1 cell lysates were analysed. First samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3% milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4°. 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-Rabbit IgG H&L (IRDye® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (ab216776) at 1/20000 dilution.

Biological function summary
Cathepsin S participates in immune system modulation and matrix degradation. It stands out in its role in the immune response cleaving antigenic proteins for presentation by MHC class II therefore influencing T-cell activation. Although synonymous with lysosomal activity it also operates extracellularly contributing to tissue remodeling and inflammation. Cathepsin S is not part of a larger complex but interacts with MHC class II impacting antigen presentation.
Pathways
This protease is critical in the immune system and extracellular matrix degradation pathways. In the context of the immune pathway CTSS interacts with other proteases such as Cathepsin L and Cathepsin B to perform antigen trimming and processing. Moreover CTSS supports the activation of T lymphocytes by ensuring the correct presentation of peptide fragments on MHC class II molecules. In matrix degradation CTSS indirectly influences collagen breakdown and interaction with other matrix metalloproteinases.

초기 취급 지침
Upon arrival, the vial should be stored in liquid nitrogen vapor phase and not at -80°C. Storage at -80°C may result in loss of viability. <p>1. Thaw the vial in 37°C water bath for approximately 1-2 minutes.<br>2. Transfer the cell suspension (0.8 mL) to a 15 mL/50 mL conical sterile polypropylene centrifuge tube containing 8.4 mL pre-warmed culture medium, wash vial with an additional 0.8 mL culture medium (total volume 10 mL) to collect remaining cells, and centrifuge at 201 x g (rcf) for 5 minutes at room temperature. 10 mL represents minimum recommended dilution. 20 mL represents maximum recommended dilution.<br>3. Resuspend the cell pellet in 5 mL pre-warmed culture medium and count using a haemocytometer or alternative cell counting method. Based on cell count, seed cells in an appropriate cell culture flask at a density of 4x10<sup>5</sup> cells/mL. Seeding density is given as a guide only and should be scaled to align with individual lab schedules.<br>4. Incubate the culture at 37°C incubator with 5% CO<sub>2</sub>. Cultures should be monitored daily.<br>5. THP-1 cells recover slowly from cryopreservation and therefore may not be ready for subculture for a number of days. Cells should be left as much as possible over this time and only subcultured when the cell density reaches 8x10<sup>5</sup> cells/mL.Small amounts of fresh media can be added until cell number/viability improves.</p>
Subculture 가이드라인
- All seeding densities should be based on cell counts gained by established methods.
- Cells should be seeded at 2x105 - 3x105 cells/mL and subcultured when they have reached 8x105 cells/mL.
- It is not recommended to allow the cell density to exceed 1x106 cells/mL.
