Proteinase Inhibitor Cocktail

Storage:
- Store at -20°C for long-term preservation.
- Avoid repeated freeze-thaw cycles to maintain efficacy.
- Once thawed, the cocktail can be stored at 4°C for short-term use (usually up to 1-2 weeks).

Product Description:
Proteinase Inhibitor Cocktails are mixtures of various inhibitors designed to protect proteins from degradation during extraction and purification. These cocktails are typically used in cell lysates, tissue extracts, and other biological samples to prevent proteolytic activity from endogenous proteases.

Key Features:
- Broad-spectrum inhibition: Effective against serine, cysteine, and metalloproteases.
- Ready-to-use: Convenient liquid format for immediate application.
- Stability: Formulated to remain effective throughout the protein extraction process.
- Versatile: Suitable for use in various types of samples, including mammalian, bacterial, and yeast extracts.
- Non-reactive: Does not interfere with downstream applications like Western blotting or enzymatic assays.

What's Included:
- 1 vial of Proteinase Inhibitor Cocktail (typically provided in a specific volume, e.g., 1 mL or 5 mL).
- Product insert with instructions for use, recommended dilution ratios, and safety information.

Applications:
- Protein extraction: Maintain integrity of proteins during cell lysis and extraction procedures.
- Biochemical assays: Protects proteins in samples used for activity assays.
- Western blotting: Prevents degradation of target proteins during sample preparation.
- Immunoprecipitation: Ensures intact protein complexes for accurate analysis.
- Mass spectrometry: Preserves protein structure for identification and characterization.
