Cathepsin-Z (CTSZ) is a lysosomal cysteine proteinase and a member of the peptidase C1 family. CTSZ, which is known also as cathepsin X and cathepsin P, exhibits carboxy-monopeptidase and carboxy-dipeptidase activities. CTSZ is expressed ubiquitously in cancer cell lines and primary tumors and as other members of this family, takes part in tumorigenesis.
CTSZ Mouse Recombinant produced in Baculovirus is a single, glycosylated, polypeptide chain containing 292 amino acids (23-306 aa) and having a molecular mass of 32.8kDa.
CTSZ is fused to a 8 amino acid His tag at C-terminus and purified by proprietary chromatographic techniques.
Sf9, Baculovirus cells.
The CTSZ solution (0.5 mg/ml) contains Phosphate Buffered Saline (pH 7.4) and 10% glycerol.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
Specific activity is > 3,000 pmol/min/ug. One unit will convert 1 pmole of Mca-PLGL-Dpa-AR-NH2 to MCA- Pro-Leu-OH per minute at pH 3.5 at 25°C.
