Cross-linked enzyme aggregates (CLEAs) have emerged as interesting biocatalyst design for immobilization. These new generation enzyme biocatalysts, CLEAs, in addition to exhibiting good mechanical stability, can be highly active, since they do not include large amounts of foreign particulate nonenzymatic material and may have increased stability. Naringinase (NGase) is an enzyme complex with hi...

Immobilization technology creates exciting new opportunities for commercial development in a wide range of industries. There are several reasons for using an enzyme in an immobilized form. In addition to more convenient handling of the enzyme, it provides for its facile separation from the product, thereby minimizing or eliminating protein contamination of the product. To date, pectinases have ...

Immobilization is often the key to optimizing the operational performance of an enzyme in industrial processes, particularly for use in non-aqueous media. Different methods for the immobilization of enzymes are critically reviewed. The methods are divided into three main categories, viz. (i) binding to a prefabricated support (carrier), (ii) entrapment in organic or inorganic polymer matrices, ...

The key to obtaining an optimum performance of an enzyme is often a question of devising a suitable enzyme and optimisation of conditions for its immobilization. In this study, laccases from the native isolates of white rot fungi Fomes fomentarius and/or Trametes versicolor, obtained from Czech forests, were used. From these, cross-linked enzyme aggregates (CLEA) were prepared and characterised...

Aggregate amyloid beta protein1-42 (Aβ1-42) can typically be found in the early stage of Alzheimer’s disease (AD). Aβ1-42 self-assembles and is highly toxic to neurons. Thus, recognizing aggregated Aβ1-42 is very important for elucidation of Aβ1-42 structure and for the diagnosis of AD. In this study, the specificity of the 79-3 monoclonal antibody against soluble aggregate Aβ1-42 was measured ...

there are many studies related to the production of a elisa kit for diagnosing virus infections. however, production of most kits depends on purification of whole virus particles, which involves the use of costly equipment and reagents. the purpose of this study was to check out if the anti-cp42 antibodies could be used as a diagnostic assay for detection of grapevine fanleaf virus (gflv). in t...

diagnosis of toxoplasma gondii (t.gondii) infection is of great medical importance especially for pregnant women and immunosuppressed patients. numerous studies have shown that the recombinant production of several ttoxoplasma antigens, including dense granule antigens (gras) has a great potential as diagnostic reagents. previous studies reported expression of amino terminal gra8 protein in fus...
