Adsorption of proteins by polystyrene microspheres

Polimery 1990, No 5, 157

DOI: dx.doi.org/10.14314/polimery.1990.157


Adsorption of various proteins at polystyrene microspheres has been investigated. It has been found that β-lipoproteides (β-LP), albumin, C-reactive protein (CRP), immunoglobulin G (IgG), and soluble antigen of leukocytes-2 (RAL-2) are immobilized on the microspheres. Adsorption of placental α1-microglobulin (PAMG-1), α2-microglobulin of fertility (AMGF), and trophoblastic β-globulin has not been observed. As a result of adsorption of proteins from the complete blood serum only the presence of β-LP on microspheres has been registered. It has been assumed that adsorption of proteins is influenced considerably by their composition, particulary by the presence of high amounts of carbohydrates.
