Tested Applications

• Positive WB detected in: HUVEC cells, THP-1 cells, U-87 MG cells
• Positive IHC detected in: human colon cancer tissue; Note: suggested antigen retrieval with TE buffer pH 9.0; (*) Alternatively, antigen retrieval may be performed with citrate buffer pH 6.0
• Positive IF/ICC detected in: U-87 MG cells

Recommended dilution

• Western Blot (WB): WB : 1:1000-1:4000
• Immunohistochemistry (IHC): IHC : 1:50-1:500
• Immunofluorescence (IF)/ICC: IF/ICC : 1:200-1:800

It is recommended that this reagent should be titrated in each testing system to obtain optimal results.

Background Information

Cathepsin S (CTSS) is a cysteine protease that plays an important role in extracellular matrix degradation and remodeling, antigen presentation, inflammation, and angiogenesis; it has been identified as a radiation response gene. In malignant tumors, CTSS induces tumor proliferation, invasion and metastasis through various mechanisms. CTSS proteins could be detected in two forms, pro-CTSS (35-37 kDa) and active CTSS (25 kDa) (PMID: 30006610, PMID: 34208434). And in this publication, it was also reporeted that active CTSS was expressed at higher levels than pro-CTSS in the lysate (PMID: 34208434).
