Protein refolding via immobilisation on crystal surfaces
… of PCMC is a recently developed method for the immobilisation protein upon the surface of a watersoluble excipient (salt, amino acid or sugar) via a co-precipitation reaction in a water miscible organic solvent. These proteins can then be used as immobilised biocatalysts in both the aqueous and …

Immobilisation of copper, chromium and arsenic on stabilised domestic refuse
The disposal of copper-chromium-arsenic, whether in solution or in combination with wood, has the potential to become a global problem. This chemical is commonly called CCA or Tanalith, and is classed as a waterborne wood preservative. Current global production of this class of chemicals is …

Einfluss kurzzeitiger Immobilisation in 6 Kopftieflage auf die Kinetik des Muskelabbaus
… increased urin excretion at the beginning of the immobilisation phase. There was a significant decrease of the 3,98% in the size of the calf muscles in the intervention group in comparisson with the non-bed rest group. The maximum voluntary calf muscle force velocity also showed a significant …

The immobilisation of Thermus strain Rt41A proteinase and its use in peptide synthesis
… less than 10%. Stability towards pH increased on immobilisation, the greatest increase in half-life being approximately 12 fold at pH 7.0 at and 80 °C. Temperature activity profiles for both the free and immobilised enzymes were very similar when using either substrate. The stability of the …

Immobilisation of Bio-molecules on Magnetisable Solid Supports for Applications in Bio-catalysts and Bio-sensors
A series of core and core-shell nanoparticles with superparamagnetic properties were synthesised and surface functionalised using three different amino-silanes by a chemical conjugation method. The functionalised nanoparticles were characterised and further modified by chemical conjugation with two …

Modulation of the angiogenic potential in collagen matrices by immobilisation of heparin and loading with vascular endothelial growth factor
The vascularization of engineered tissues in many cases does not keep up with the ingrowth of cells. Nutrient and oxygen supply are not sufficient, which ultimately leads to the death of the invading cells. The enhancement of the angiogenic capabilities of engineered tissues therefore represents a …

The synthesis and chemistry of new carbosilane dendrimers and their use in polymerisation catalysis
The immobilisation of homogeneous catalysts is an area of research that attracts a great dela of attention. The immobilisation of catalysts on organic polymers and on inorganic materisl such as silica is a well known strategy. Recently, dendrimers have also been used as support materials. In this …

The effects of biochar on trace element and nutrient solubility in the presence of low-molecular-weight organic acids
… batch experiments examined the biochar-driven immobilisation of trace elements and nutrients with and without LMWOAs. Then, batch studies tested if biochar would reduce the LMWOA-driven solubilisation of trace elements and nutrients in soil. Later, rice husk biochar and LMWOA-activated rice …

Preparation of a self-contained NADH co-factor recycling particle system
… recycling method. A few methods for the co-immobilisation of enzymes and co-factors have been developed. These systems are of interest as they offer the advantages of recycling the enzymes together with the co-factor, thereby enabling re-use. The immobilisation of enzymes also provides a …

Characterisation of the hydantoin-hydrolysing activity of pseudomonas putida strain RUKM3s and development of biocatalyst for amino acid production
… purified for characterisation, stabilised by immobilisation, and applied as a biocatalyst for production of amino acids from 5-mono-substituted hydantoin substrates. Experiments were devised to optimise conditions for the production of RUKM3s biomass with high levels of hydantoin hydrolysing …

Klinische Studien über die Immobilisation von Mantelpavianen (Papio hamadryas) unter Verwendung der "Hellabrunner Mischung" und über den postnarkotischen Einfluss von Atipamezol und Yohimbin im Vergleich zu Etilefrin als Aufwachbeschleuniger
The objective of the present study was to examine the effectiveness of the anesthetic combination "Hellabrunne mixture" ("HM" = approximately 125mg xylazine/ml and 100mg ketamine/ml) on hamadryas baboons, as well as the influence of various drugs over the time it took the baboons to wake up (their …

Development and physiological characteristics of avian fast and slow contracting muscles
… during the first two weeks of ex ovo growth. Immobilisation in both positions caused the histochemically displayed activities of these enzymes to become reduced. 3. Biochemically assays for Mg 2+-activated myofibrillar ATPase (both a alone and total activity a+ b) activity were developed for …
