High levels of penetrating cryoprotectants (CPAs) can eliminate ice formation during
cryopreservation of cells, tissues, and organs to cryogenic temperatures. But CPAs become …

One of the major barriers to the use of enzymes in industrial biotechnology is their
insufficient stability under processing conditions. The use of organic solvent systems instead …

Modification of therapeutic proteins and peptides by polyethylene glycol (PEG) conjugation
is a well-known approach to improve the pharmacological properties of drugs. Several …

In this study, we immobilized pectinase preparation on porous zeolite ZSM-5 as an enzyme
carrier. We realized this immobilized enzyme catalyst, pectinase preparation@ ZSM-5, via a …

Rhus laccase (RL) was covalently immobilised onto chitosan, and the effects of
immobilisation on pH optimum, enzyme activity, thermostability, and re-use evaluated, using …

Haloalkane dehalogenases are microbial enzymes with a wide range of biotechnological
applications, including biocatalysis. The use of organic co‐solvents to solubilize their …

The immobilized enzymes' properties can be affected by cross-linkers on the surface of
supports. To study how cross-linkers alter enzymes function, chitosan-coated magnetic …

The effect of glycerol and sorbitol on the stability of porcine pancreas trypsin was
investigated in this work. Molecular dynamics simulation and thermostability results showed …

In recent years enzymes had many applications, such as catalysts in organic synthesis and
producing biosensors. In this study, nitrogen-doped graphene quantum dots (NGQDs) were …

The purpose of this study was to propose a new preparation method to fabricate insulin-
loaded poly (lactic-coglycolic acid)(PLGA) microparticles satisfying protein loading, release …
