Enzyme immobilization on heparin
Journal of Biomedical Materials Research, 1978AbstractWe describe the preparation and some of the properties of heparin‐bound α‐chymotrypsin that were obtained via activation of heparin with water‐soluble carbodiimide. Immobilized enzyme has unchanged kinetic characteristics toward low‐molecular‐weight and macromolecular substrates.

Enzyme immobilization on fibrin
Biotechnology and Bioengineering, 1976The following conclusions can be drawn concerning the utilization of fibrin to immobilized enzyme systems. Fibrin can be used both as a powder or membrane, to covalently immobilize trypsin with retention of activity. Carbon-14 labeled trypsin can be used to estimate the amount of immobilized enzyme on a proteinaceous support.

Enzyme immobilization on tritylagarose
Biotechnology and Bioengineering, 1982AbstractA method is described for the immobilization on tritylated agarose or Sepharose columns of a wide spectrum of enzymes, including types useful in contemporary biochemistry/molecular biology, many of which have never before been reported as immobilized.

Enzyme Immobilization by Adsorption
2003Much has already been written on the subject of biocatalyst (cell/enzyme) immobilization, and it is not the function of a text such as this to go into all the various aspects of the field. For general reviews on the area, the reader is referred to refs. 1-3.

Enzyme Immobilization by Entrapment
2003Entrapment methods of immobilization are mostly used in cell immobilization procedures, but have found some application with enzymes, particularly when the enzyme is essentially a dead cell or crude homogenate(1). In theory the entrapped enzyme is not attached to the polymer; its free diffusion is merely restrained. In practice, however, some or all of

Enzyme immobilization in porous solid supports—penetration of immobilized enzyme
Biotechnology and Bioengineering, 1984AbstractThe process of enzyme immobilization under the diffusion‐controlled regime (i.e., fast attachment of enzyme compared to its diffusion) is modeled and theoretically solved in this article. Simple and compact solutions for the penetration depth of immobilized enzyme and the bulk enzyme concentration versus time are presented.
