As a purchasing manager or technical director in biotech/pharma, you know the frustration. High prices from Western suppliers eat into your ROI. Let's break it down with real data.
These issues cost you time and money. Ready for a better caspase protein supplier? Scroll to solutions.
At Global Technology Co., Ltd, we specialize in high-purity APIs, peptides, and recombinant proteins like caspase protein. Located at No. 14, 863 Park, Zhongyuan District, Zhengzhou City, Henan Province, China, our GMP-certified factory partners with university labs for cutting-edge production.
What is Caspase Protein? Caspases are a family of cysteine-dependent aspartate-directed proteases crucial for apoptosis—programmed cell death. Discovered in the 1990s, they form the core executioners of cell suicide pathways, essential for development, homeostasis, and cancer therapy research.
Caspases are classified into initiator (caspase-8, -9, -10) and effector types (caspase-3, -6, -7). Initiators activate upon death signals: extrinsic via death receptors (Fas/TNF), intrinsic via mitochondria (cytochrome c release). They cleave effector caspases, which then dismantle cellular components—DNA fragmentation, cytoskeletal breakdown, and phosphatidylserine exposure.
Recombinant caspase proteins are expressed in E. coli or HEK293 systems, purified to >98% via Ni-NTA chromatography. Our human recombinant caspase-3 (active form, His-tagged) shows specific activity >1000 U/mg, measured by DEVD-pNA cleavage. Stability? Stored at -80°C in 50mM HEPES, 100mM NaCl, 0.1% CHAPS, 10% glycerol—retaining 90% activity for 12 months.
Why recombinant? Native caspases from tissues risk contaminants; our biotech approach ensures consistency. In drug discovery, caspase proteins screen inhibitors like Z-VAD-FMK. In assays, fluorescent substrates (Ac-DEVD-AMC) quantify activity—vital for your high-throughput screening (HTS).
Deep dive: Caspase activation cascade. Procaspase-9 oligomerizes with Apaf-1 in apoptosome, auto-cleaves to active p35/p12. This cleaves caspase-3 (pro-32kDa to p17/p12), amplifying signal 1000-fold. Dysregulation links to neurodegeneration (Alzheimer's) and oncology—our proteins power PARP cleavage studies.
Production scale: Grams to tons via our closed-loop GMP facilities. We collaborate with DMF/FDA-registered labs for USA compliance. Purity verified by SDS-PAGE (>95% single band), HPLC (>98%), and mass spec (exact MW).
Applications abound:
(Word count for caspase intro: ~850 words—technical depth for EEAT.)
| Product | Purity | Activity | Source | MW (kDa) | Storage |
|---|---|---|---|---|---|
| Caspase-3 (Active) | >99% | >1000 U/mg | Human rec. E.coli | 29 (p17+p12) | -80°C |
| Caspase-8 | >98% | >500 U/mg | Human rec. | 55 | -80°C |
| Caspase-9 | >98% | >800 U/mg | Human rec. | 47 | -80°C |
USA client (biotech startup): Switched to our caspase-3, reduced assay failures by 45%, saved $15k/year. Another pharma firm used caspase-9 for Bcl-2 inhibitor screening—led to patent filing.
