β-Lactoglobulin adsorption equilibrium at low- and high-energy surfaces

Creator:: Al-Malah, Kamal Issa Masoud
Abstract:: Ellipsometry was used to study the effects of surface energetics and temperature on the equilibrium adsorptive behavior exhibited by β-lactoglobulin. β-Lactoglobulin isotherms at 25, 37, and 55°C were constructed for this purpose. The surfaces of acrylic, polycarbonate, polyester, glass, and #304 stainless steel were contacted with protein solutions of varying...

The effect of pH and ionic strength on the adsorption of β-lactoglobulin onto well-characterized silicon

Creator:: Luey, Ja-Kael
Abstract:: The effect of pH and ionic strength on the equilibrium adsorptive behavior of β-lactoglobulin onto hydrophobic and hydrophilic silicon surfaces was studied using ellipsometry. Plots of amount adsorbed (μg protein/cm²) as a function of protein concentration (mg/ml) exhibited attainment of plateau values beyond a protein concentration of 0.250 mg/ml. At...

Retention of protein repulsive character and antimicrobial activity of PEO brush layers following nisin entrapment

Creator:: Auxier, Julie A.
Abstract:: Nisin, an amphiphilic, antimicrobial peptide, has been shown to integrate into the hydrophobic inner region of poly(ethylene oxide) (PEO) brush layers; however, the presence of integrated nisin may compromise the protein repulsive character of the PEO layer. In particular, the introduction of fibrinogen to nisin-loaded brush layers has been observed...

Molecular origins of peptide entrapment in polyethylene oxide layers

Creator:: Wu, Xiangming
Abstract:: A more quantitative understanding of peptide entrapment and elution from otherwise protein-repellent polyethylene oxide (PEO) brush layers will provide direction for development of new strategies for drug storage and delivery. Here we describe criteria for peptide integration and structural change within the PEO brush, and discuss the reversibility of peptide...

The adsorption of human recombinant factor VIII in the presence of the nonionic triblock surfactant Pluronic® F-68 at the air-water interface

Creator:: Alkhatib, Aveen K.
Abstract:: The adsorption behavior of a human recombinant Factor VIII (rFVIII) in the presence of the nonionic, poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) triblock surfactant Pluronic® F-68 was evaluated by dynamic air-water tensiometry. Surface tension kinetics were recorded for F-68 in the absence of protein at concentrations ranging from 0 to 10,000...

Synthesis and evaluation of PEO-coated materials for microchannel-based hemodialysis

Creator:: Heintz, Keely
Abstract:: The marked increase in surface-to-volume ratio associated with microscale devices for hemodialysis leads to problems with hemocompatibility and blood flow distribution that are more challenging to manage than those encountered at the conventional scale. In this work, stable surface modifications with pendant polyethylene oxide (PEO) chains were produced on polycarbonate...

Quantifying nisin adsorption behavior at pendant polyethylene oxide brush layers

Creator:: Dill, Justen K.
Abstract:: A more quantitative understanding of peptide loading and release from polyethylene oxide (PEO) brush layers will provide direction for development of new strategies for drug storage and delivery. The antimicrobial peptide nisin shows potent activity against Gram-positive bacteria including the most prevalent implant-associated pathogens, its mechanism of action minimizes the...

Interaction of recombinant factor VIII and the nonionic surfactant Tween 80 at interfaces

Creator:: Joshi, Omkar
Abstract:: The role of the nonionic surfactant Tween 80 on the behavior of the therapeutic recombinant protein Factor VIII (rFVIII) was investigated at solid/liquid and air/water interfaces. In order to provide a model system to compare results obtained for the complicated rFVIII-Tween system, a well-characterized globular protein lysozyme was used. The...
