Interaction of PC-3 cells with fibronectin adsorbed on sulfonated polystyrene surfaces.
The ability of cancer cells to invade neighboring tissues is crucial for cell dissemination and tumor metastasis. It is generally assumed that cell adhesion to extracellular matrix proteins is an important stage of cancer progression. Hence, adhesion of cancer cells under in vitro conditions to proteins adsorbed on a substratum surface has been studied to provide a better understanding of cell-...
متن کاملInteraction of apo cytochrome c with sulfonated polystyrene nanoparticles.
Stable nanoparticle dispersion in aqueous solutions was obtained with partially sulfonated polystyrene. The hydrophobic association of the backbone chains and phenyl groups is balanced by the electrostatic repulsion of the sulfonate groups on the particle surface. The size distribution of the sulfonated polystyrene particles in relation to concentration, degree of sulfonation and chain length, ...
متن کاملProtonation of polyaniline with lightly sulfonated polystyrene
Protonation of polyaniline base with lightly sulfonated polystyrene in polar solvents such its dimethyl sulfoxide and N-methyl-2-py~olidone was investigated by UV-Vis absorption spectra. As the molar ratio of sulfonated polystyrenelpolyaniline increases, the conversion from polyaniline base form to salt form is observed owing 10 incrensed protonation. The isosbestic point clearly shows that qui...
متن کاملHeparin Interaction with Protein-Adsorbed Surfaces t
Albumin and fibrinogen show no binding affinity to varied molecular weights ofhepafin at physiological pH. Human plasma fibronectin was shown to bind heparins in both the solution and adsorbed states. Fibronectin was shown to have six active binding sites for heparins which may be stericaUy blocked in some adsorbed states. 125I-Fibronectin monolayer concentrations were shown to be significantly...
متن کاملNMR Analysis of Sulfonated Polystyrene
Atactic polystyrene (PS) has an amorphous structure. Compounds such as H2SO4 and SO3 are commonly used as sulfonating agents for various polymers, including PS. The main purpose of this work is to study chemical structural changes in PS arising from sulfonation through DSC analysis and NMR spectroscopy. An increase in the glass transition temperature (Tg) of sulfonated polystyrene and a decreas...
