CTSF Human, Sf9

Source:Sf9, Baculovirus cells.Physical Appearance:Sterile filtered colorless solution.Biological ActivitySpecific activity is > 5 pmol/min/ug, and is defined as the amount of enzyme that hydrolyze 1pmole of Z-Phe-ArgAMC to Z-Phe-Arg and AMC per minute at pH 5.0 at 37?.Cathepsin F (CTSF) is a member of the peptidase C1 family. Cathepsins are papain family cysteine proteinases which are a main component of the lysosomal proteolytic system. The CTSF gene is ubiquitously expressed, and it maps to chromosome 11q13, close to the gene encoding cathepsin W. CTSF plays a role in normal protein catabolism. CTSF is involved in some degradative processes occurring in tumor progression since it is highly expressed in some cancer cell lines.CTSF produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 474 amino acids (20-484.a.a) and having a molecular mass of 52.5kDa.CTSF is expressed with a 6 amino acid His tag at C-Terminus and purified by proprietary chromatographic techniques.
