Thermo Scientific™ Pierce™ Protease Inhibitor Tablets, EDTA-free, are a convenient and effective solution for protecting proteins from degradation during cell lysis and protein extraction workflows. These tablets contain a broad-spectrum mixture of protease inhibitors that target multiple classes of proteolytic enzymes, ensuring preservation of protein integrity in both tissue and cultured cell samples.
Designed for ease of use and compatibility with downstream applications, each tablet dissolves rapidly to produce a clear solution and is sufficient for preparing 50 mL of lysis buffer or sample solution.
Key Features
Broad-Spectrum Protease Inhibition
- Inhibits serine, cysteine, aspartic proteases, and aminopeptidases
- Protects proteins from enzymatic degradation during extraction
- Ensures integrity of target proteins for accurate downstream analysis
EDTA-Free Formulation
- Suitable for applications requiring metal-dependent enzymes or metalloproteins
- Avoids interference with metal-sensitive assays and workflows
Convenient and Ready-to-Use
- Pre-formulated tablets eliminate the need for complex reagent preparation
- Dissolves quickly to form a clear solution
- One tablet treats 50 mL of buffer or lysate
Compatible with Common Assays
- Fully compatible with Pierce BCA Protein Assay
- Suitable for use with detergent-based lysis buffers
- Can be combined with phosphatase inhibitors if required
Cost-Effective and Efficient
- Economical alternative to liquid inhibitor cocktails
- Long shelf life when stored at 2–8°C
- Consistent performance across batches
Applications
- Protein extraction from tissue samples
- Cell lysis in cultured cells
- Proteomics and protein analysis workflows
- Western blotting and immunoassays
- Enzyme activity studies and protein purification
Mechanism of Action
Proteases released during cell lysis can rapidly degrade proteins, compromising experimental results. Pierce Protease Inhibitor Tablets contain a combination of inhibitors that act on different protease classes:
- AEBSF – inhibits serine proteases
- Aprotinin – inhibits serine proteases
- Bestatin – inhibits aminopeptidases
- E-64 – inhibits cysteine proteases
- Leupeptin – inhibits serine and cysteine proteases
- Pepstatin A – inhibits aspartic proteases
This multi-target inhibition ensures comprehensive protection of proteins throughout the extraction process.
