GRADE & PURITYAnimal Free?Animal-free — produced without animal-derived components to reduce contamination risk. Use in biomanufacturing and culture avoiding animal-origin material.Carrier Free?Carrier-free — supplied without added carrier protein/stabilizer. Use when carriers (e.g. BSA) would interfere with conjugation or sensitive assays.Bioactive?Bioactive grade — verified to retain biological activity in functional assays. Use when the molecule must be functionally active, not just pure.ActiBioPure™?ActiBioPure™ — Aladdin's premier line for bioactive and recombinant products. Use when both high purity and preserved biological activity are required.Azide Free?Azide-free — without sodium azide preservative. Use in conjugations, cell work, or assays where azide is toxic or inhibitory.His Tag?His tag grade — recombinant protein bearing a His tag for affinity purification/detection. Use to purify, immobilize, or detect the tagged protein.≥90%(SDS-PAGE)See COA

Accession #
P25774-1
Protein Tag
C-8×His
Expression system
HEK293
Endotoxin Concentration
<0.1 EU/μg
Bioactivity
Measured by its ability to cleave a fluorogenic peptide substrate, (7-methoxycoumarin-4-yl) acetyl-Arg-Pro-Lys-Pro-Val-Glu-Nva-Trp-Arg-Lys (2, 4-dinitrophenyl)-NH2. Cleavage of substrate can be measured using excitation and emission wavelength at 320 nm and 405 nm, respectively.The specific activity is >300 pmoles/min/μg.

Recombinant Human Cathepsin S protein (rp143673) - SDS-PAGE 2 μg/lane of Recombinant Human Cathepsin S Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing the bands at 39 kDa (Pro) & 28 kDa (mature). Human Cathepsin S is synthesized as a preproenzyme of 331 amino acid residues consisting a signal peptide (residues 1‑16), a pro region (residues 17‑114), and the mature enzyme (residues 115‑331).
