Thermo Scientific™ Protein Stabilizing Cocktail, 10 mL

Thermo Scientific™ Protein Stabilizing Cocktail is a ready-to-use, 4X concentrated stabilization solution formulated to extend the shelf-life of purified or partially purified proteins, including enzymes, antibodies, and cytokines. This low-viscosity, non-toxic reagent protects biomolecules against freeze-thaw cycles, oxidation, aggregation, and other environmental stressors that commonly reduce protein activity and structural integrity during routine storage.

Unlike glycerol-based formulations, the cocktail is easier to pipette and is fully dialyzable, making it suitable for workflows requiring reagent removal before downstream applications.

Key Features & Benefits

• Enhanced Protein Stability
  Provides significant protection against inactivation and degradation under refrigerated or frozen storage.
• Versatile Compatibility
  Stabilizes a broad range of protein types, including kinases, phosphatases, restriction enzymes, peroxidases, luciferases, cytokines, and antibodies.
• Low Viscosity
  Easier to handle than 50% glycerol, ensuring precise pipetting.
• Nontoxic & Assay-Compatible
  Does not interfere with most downstream applications; components are fully removable via dialysis or desalting.
• Convenient Concentrate Format
  Supplied as a 4X buffer-compatible concentrate; simply dilute as needed for protein stabilization.

Technical Specifications

Applications

• Long-Term Protein Storage
  Extends the shelf-life of purified or partially purified proteins in frozen or refrigerated conditions.
• Enzyme Stabilization
  Protects labile enzymes such as kinases, phosphatases, restriction enzymes, and luciferases during storage and repeated freeze-thaw cycles.
• Antibody & Cytokine Preservation
  Maintains biological activity and structure during refrigerated storage or sample shipping.
• Functional Assays & ELISA Sample Prep
  Ensures reproducibility and stability of protein standards and controls.

Thermo Scientific™ Protein Stabilizing Cocktail offers a powerful, versatile solution for maintaining protein integrity during routine storage and handling. With broad compatibility, low viscosity, and dialyzability, this reagent is an excellent choice for researchers requiring high protein stability without assay interference. Ideal for applications in enzyme studies, proteomics, immunology, and biochemistry.
