Andrade, Human and hen lysozyme adsorption A comparative study using total internal reflection fluorescence spectroscopy and molecular graphics, in Proteins at Interfaces Physicochemical and Biochemical Studies (J. L. Brash and T. A. Horbett, eds.), ACS Symposium Series No. 343, pp. 290-305, American Chemical Society, Washington, D.C. (1987). [Pg.340]

In 1982, an azo-dye-containing copolymer of 2-hydroxymethyl methacrylate was used for modulation of lysozyme adsorption on polymer beads. The amount of the protein adsorbed on a microsphere decreased upon irradiation, but rather long... [Pg.5]

In contrast to these approaches based on nonspecific interactions, Zhang and coworkers described a molecularly imprinted hydrogel based on the ther-moresponsive PNIPAM [184], This hydrogel was prepared by copolymerization of a metal chelate monomer iV-(4-vinyl)-benzyl iminodiacetic acid, which formed a coordination complex with the template protein in the presence of Cu ions, A-isopropylacrylamide, acrylamide, and IV.lV-methylenebisacrylamide as crosslinker. The interaction of the imprinted thermoresponsive hydrogel with the protein could be switched between coordination effects and electrostatic attraction by addition or omission of Cu ions. Furthermore, this imprinted hydrogel allowed switching of lysozyme adsorption by changing the temperature. [Pg.22]

Fig. 10. External reflection FTIR spectra for lysozyme adsorption to stearic acid in its condensed phase state (at 20 A2/molecule). (a) The spectral regions corresponding to CH2 stretch vibrations (2820-2960 cm ) and the amide I vibration (1500— 1750 cm ). (b) Peak area against time for CH2 asymmetric stretch (triangle) and the amide I stretch (square). Peak area was calculated between 2940 and 2900 cm 1 for the CH2 asymmetric stretch, and between 1680 and 1600 cm 1 for the amide I peak. Taken from Ref. [76] with permission from The Royal Society of Chemistry. Fig. 10. External reflection FTIR spectra for lysozyme adsorption to stearic acid in its condensed phase state (at 20 A2/molecule).

In many cases the adsorption rate is diffusion controlled, at least in the initial stages, with the rate adequately described by Eqs. (6) and (7) at low surface pressures [30-33]. The F versus t 12 plots for /3-casein and lysozyme adsorption at air/water interface give straight... [Pg.7]

Albumin and lysozyme adsorption were minimal on the 35% HEMA / 65% EMA copolymer but IgG adsorption was at a maximum on this surface. [Pg.248]

Our lab Is using two rather recently Introduced techniques to offer a comparative study of human and hen lysozyme adsorption on three different model surfaces. [Pg.291]

Adsorbed mass of wild type of T4 lysozyme was registrated on hydrophilic and hydrophobic surfaces after 30 min and, respectively, consists of 2.84 mg/m and 3.28 mg/m. For Ile3->Cys (S-S), Ile3->Trp mutants these values were much reduced, in the same time the mutant Ile3->Ser shows a much greater adsorption, respectively, 4.29 and 3.80 mg/m. The end-on T4 lysozyme adsorption corresponds to ultimate value of 3.96 mg/m, and side-on one to... [Pg.795]
