Thermo Scientific™ Pierce™ Protease and Phosphatase Inhibitor Mini Tablets provide a comprehensive solution for protecting proteins during cell lysis, extraction, and purification workflows. Each tablet contains a carefully balanced combination of protease and phosphatase inhibitors, delivering broad-spectrum protection against both proteolytic degradation and dephosphorylation.
This formulation includes EDTA, enabling inhibition of metalloproteases in addition to other protease classes. Each mini tablet is designed for small-volume applications and is sufficient for 10 mL of lysis buffer or sample solution, making it ideal for precise and controlled experimental setups.
Key Features
Dual Protection System
- Simultaneous inhibition of proteases and phosphatases
- Prevents protein degradation and loss of phosphorylation
- Maintains structural and functional integrity of proteins
Broad-Spectrum Protease Inhibition
- Targets serine, cysteine, aspartic proteases, and metalloproteases
- Contains aprotinin, bestatin, E-64, leupeptin, and EDTA
- Ensures comprehensive protection during extraction
Effective Phosphatase Inhibition
- Inhibits serine/threonine and tyrosine phosphatases
- Includes sodium fluoride, sodium orthovanadate, sodium pyrophosphate, and β-glycerophosphate
- Preserves phosphorylation-dependent signaling pathways
Convenient Mini Tablet Format
- Pre-measured tablets for accurate dosing
- Rapid dissolution into clear solution
- One tablet treats 10 mL of buffer or lysate
Optimized for Laboratory Workflows
- Compatible with Pierce BCA Protein Assay
- Suitable for detergent-based lysis buffers
- Integrates easily into standard protein extraction protocols
Applications
- Protein extraction and purification
- Cell lysis for signaling pathway analysis
- Phosphoproteomics and kinase studies
- Western blotting and immunoassays
- Enzyme activity and protein stability studies
Mechanism of Action
During cell lysis, endogenous proteases degrade proteins while phosphatases remove critical phosphate groups, affecting protein function and signaling pathways. These mini tablets combine inhibitors that target both enzyme groups:
Protease inhibitors:
- Aprotinin – serine proteases
- Bestatin – aminopeptidases
- E-64 – cysteine proteases
- Leupeptin – serine and cysteine proteases
- EDTA – metalloprotease inhibition
Phosphatase inhibitors:
- Sodium fluoride – serine/threonine phosphatases
- Sodium orthovanadate – tyrosine phosphatases
- Sodium pyrophosphate – broad phosphatase inhibition
- β-glycerophosphate – serine/threonine phosphatases
This dual-action system ensures maximum protection of proteins and their post-translational modifications.
