Enzyme-albumin polymers

Poznansky et al. have recently reported interesting work describing the use of albumin polymers as carriers of enzymes (for enzyme replacement therapy or as antitumour agents Enzyme-albumin polymers have been prepared using... [Pg.94]

In the present studies, a Fourier-transform infra-red spectrometer in attenuated total reflectance mode (FT-IR-ATR) was used to characterize the albuminated polymer membrane surface. FT-IR-ATR is a powerful surface analysis technique in which a spectrum of only a few micron thick surface layer is obtained. As albumin or enzymes were attached only on the surfaces of polypropylene, FT-IR-ATR technique was ideally suited for the their analysis. [Pg.156]

Degradation can take place by one or both mechanisms. For example, natural polymers such as albumin may be used such proteins are not only water-soluble, but are readily degraded by specific enzymes. The terms degradation, dissolution and erosion are used interchangeably in this chapter, and the general process is referred to as polymer degradation. [Pg.88]

When a polymer is treated with enzymes for surface modification, some of the undesired protein tends to adsorb on the polymer surface, which subsequently creates problems in the surface analysis and causes a slow down in the rate of catalysis. Adsorbed proteins can be removed from the surfaces by washing with large volumes of 1.5% Na2C03 and water (Eischer-Colbrie et al., 2006) as part of a preparation for surface analysis. Protein-resistant molecules such as polyethylene glycol can be used to prevent the nonspecific protein adsorption. Surfaces can be precoated with an inert protein such as bovine serum albumin (Salisbury et al., 2002) for increasing the rate of catalysis. [Pg.101]
