Application

  • Use as a cryoprotectant in a variety of cell freezing media
  • Used in excipeint research

Biochem/physiol Actions

Trehalose is a non-reducing sugar formed from two glucose units joined by a 1-1 alpha bond. It is thought to provide plants and animals with the ability to withstanding periods of dehydration.

Features and Benefits

  • Prepared from Saccharomyces cerevisiae
  • Suitable for use with HPLC and GC-MS(4)

General description

D-(+)-Trehalose, a disaccharide, acts as a chemical chaperone and serves as a carbohydrate reserve in microorganisms. It functions as an osmolyte, safeguarding cells against various environmental stresses. Further, it also plays a crucial role in protein stabilization during freeze drying, making it a valuable asset in the areas of biochemical, cell culture, and excipient research

This report extensively explores the benefits of including chitosan into poly-ε-caprolactone (PCL) nanoparticles (NPs) to obtain an improved protein/antigen delivery system. Blend NPs (PCL/chitosan NPs) showed improved protein adsorption efficacy (84%) in low shear stress and aqueous environment, suggesting that

In frozen and lyophilized systems, the biological to be stabilized (e.g. therapeutic protein, biomarker, drug-delivery vesicle) and the cryo-/lyo-protectant should be co-localized for successful stabilization. During freezing and drying, many factors cause physical separation of the biological from the cryo-/lyo-protectant

The importance of cake adhesion to the inside vial wall during lyophilization of amorphous trehalose cakes was determined by using hydrophobized vials. The degrees of cake shrinkage and cracking were determined independently by photographic imaging of the cake top surface

The inactivation of catalase during spray-drying over a range of outlet gas temperatures could be closely represented by the Arrhenius equation. From this an activation energy for damage to the catalase could be calculated. The close fit to Arrhenius suggests

The spray-drying behaviour of 16 water-miscible organic solvents on a bench-scale machine (Büchi B290 with inert loop) was determined under mild-to-moderate process conditions, namely inlet gas temperature of 130 °C and liquid feed flow rate of ≤3 mL/min. The solvents with boiling
