CTSZ Human, Sf9

Source: Sf9, Baculovirus cells.Sterile Filtered clear solution.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 produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 288 amino acids (24-303.a.) and having a molecular mass of 32.5kDa. (Molecular size on SDS-PAGE will appear at approximately 28-40kDa) .CTSZ is expressed with an 8 amino acid His tag at C-Terminus and purified by proprietary chromatographic techniques.

Functional Assay

Greater than 95% as determined by SDS-PAGE.

CTSZ protein solution (0.5mg/mL) contains 10% glycerol & Phosphate Buffered Saline (pH 7.4) .

Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA) .Please avoid freeze thaw cycles.

The specific activity is determent as the ability of 1 unit to convert 1.0 pmole of Mca-PLGL-Dpa-AR-NH2 to MCA- Pro-Leu-OH per minute at pH 3.5 at 25C and is > 1,400 pmol/min/ug.
