Molecular properties influencing the surface activity of α-lactalbumin, β-lactoglobulin and bovine serum albumin

Creator:: Suttiprasit, Prasert
Resource Type:: Dissertation
Full Text:: effects of temperature and protein concentration on adsorbed mass recorded at hydrophobic and

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...

Elution of adsorbed proteins at hydrophobic and hydrophilic surfaces by dodecyltrimethylammonium bromide and sodium dodecyls sulfate

Creator:: Vinaraphong, Pravina
Abstract:: Adsorption kinetic data recorded for α-lactalbumin, β-casein, β-lactoglobulin, bovine serum albumin and lysozyme at silianized silica surfaces of low and high hydrophobicity, along with a simple model for adsorption and surfactant-mediated elution of protein, were used to analyze the removal of each protein by sodium dodecylsulfate (SDS) and dodecyltrimethylammonium bromide...

Molecular origins of surfactant-mediated stabilization of protein

Creator:: Lee, Hyo Jin
Abstract:: Nonionic surfactants are commonly used to stabilize proteins during upstream and downstream processing and drug formulation. Surfactants stabilize the proteins through two major mechanisms: (i) their preferential location at nearby interfaces, in this way precluding protein adsorption; and/or (ii) their association with protein into "complexes" that prevent proteins from interacting...

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...
Resource Type:: Masters Thesis
Full Text:: hemodialyzer test articles. These coatings were evaluated in relation to protein repulsion, impact on urea

The influence of preadsorbed milk proteins on adhesion of Listeria monocytogenes to silica surfaces

Creator:: Al-Makhlafi, Hamood K.
Abstract:: β-lactoglobulin (β-Lg), bovine serum albumin (BSA), α-lactalbumin (α-Lac), and β-casein were adsorbed onto silanized silica surfaces of low and high hydrophobicity for 8 h, and β-Lg and BSA for 1 h. The surfaces were incubated in buffer for 0, 5, 10, or 15 h and then contacted with Listeria monocytogenes...

The influence of surface functional groups on β-lactoglobulin adsorption equilibrium

Creator:: Al-Makhlafi, Hamood K.
Abstract:: Interactions between proteins and contact surfaces can have important implications in the food industry. Such interactions contribute to the course of fouling of membrane surfaces and they appear to mediate bacterial and spore adhesion to some degree as well. In addition to protein and solution properties, interfacial behavior is strongly...
Resource Type:: Masters Thesis
Full Text:: protein and solution properties, interfacial behavior is strongly influenced by contact surface

Macroscopic model for apparent protein adsorption equillibrium at hydrophobic solid-water interfaces

Surfactant interactions with recombinant factor VIII at the air/water interface

Creator:: Chu, Liping
Abstract:: The surface tension kin'ti4tnd ste'dy state behavior exhibited by mixtures of selected surfactants with a recombinant Factor VIII (rFVIII) were evaluated with automated interfacial tensiometry. In particular, fresh solutions of rFVIII with different concentrations of Tween 80, sodium dodecylsulfate (SDS), or dodecyltrimethylammonium bromide (DTAB) were prepared and their surface tension...

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...
