In this review, we detail the efforts performed to couple the purification and the immobilization of industrial enzymes in a single step. The use of antibodies, the development of specific domains with affinity for some specific supports will be revised. Moreover, we will discuss the use of domains that increase the affinity for standard matrices (ionic exchangers, silicates). We will show how ...

Hydroxynitrile lyases are a versatile group of enzymes that are applied both in the laboratory and on an industrial scale. What makes them particularly interesting is that to date five structurally unrelated categories of hydroxynitrile lyases have been discovered. Given their great importance they have often been immobilised utilising many different methodologies. Therefore the hydroxynitrile ...

Most of the supports for enzymeimmobilization are artificial materials, and chemical reactions are also required to immobilize the enzymes in most cases.1] These support materials and chemicals for immobilization must not be allowed to contaminate final products, especially foods or drugs. The requirements to achieve this are tedious, costly, and may have the wrong effects on enzyme activities....

The immobilization and differential pulse anodic voltammetry (DPAV) of a 20-mer oligonucleotide related to the human interleukine-2 (hIL-2) using renewable pencil graphite electrode (PGE) is described. The influences of electrochemical pretreatment of PGE on the ability of the electrode in hIL-2 adsorption, and conditions of hiIL-2 immobilization on PGE including immobilization potential and ti...

CONTEXT When cervical spine injuries are suspected, the cervical spine should be immobilized in a neutral position and neck motion controlled in preparation for transport to an emergency facility. Protocols for emergency transport utilizing common devices (cervical collars) and methods (transfer techniques) during these procedures are not entirely evidence based. EVIDENCE ACQUISITION The medi...
