Interaction of immunoglobulins with liposomes.
Liposomes were used as model targets to test the effect of immunoglobulins on biomembranes. Heat-aggregated immunoglobulins (Ig) exceeded native immunoglobulins in their capacity to release anions and glucose from model liposomes (either lecithin-dicetyl-phosphate-cholesterol or lecithin-stearylamine-cholesterol in molar ratios of 7:2:1). This interaction was not dependent upon the presence of ...
متن کاملstudy of dna interaction with ethylenediaminetetraacetic acid and sesamol food additives
برهمکنش dnaتیموس گاوی طبیعی (ct-dna) با اتیلن دی آمین تترااستات (edta)در بافرtris-hcl با 8/7 ph ( دراین ph،edta به نمک دی سدیم تبدیل می شود) وسسامول در بافر tris-hcl با4/7 ph مورد بررسی قرار گرفته است. edta و سسامول استفاده فراوانی در تکنولوژی غذایی و صنعت شیمیایی دارند. مدل اتصال dna مربوط بهedta بوسیله اسپکتروفتومتری جذب، دورنگ نمایی حلقوی(cd)، ویسکومتری وژل الکتروفورز بررسی شده است. طیفuv ...
15 صفحه اولInteraction of rotavirus particles with liposomes.
We have studied the interactions of purified viral particles with liposomes as a model to understand the mechanism of entry of rotavirus into the cell. Liposomes, made from pure as well as mixed lipids, that contained encapsulated self-quenching concentrations of the fluorophore carboxyfluorescein (CF) were used. Rotavirus-liposome interactions were studied from the fluorescence dequenching of ...
متن کاملInteraction of phosphoglycerate kinase with phosphatidylserine liposomes.
The interaction of 3-phosphoglycerate kinase from bovine heart with natural phosphatidylserine (I) and synthetic dipalmitoyl phosphatidylserine (II) in form of liposomes was investigated by measuring fluorescence and activity of the enzyme. The addition of increasing amounts of I resulted in progressive quenching of protein fluorescence with no shift in the emission maximum. In contrast, II did...
متن کاملUltrastructural studies of the interaction of spectrin with phosphatidylserine liposomes.
Spectrin was shown previously to interact with phosphatidylserine and phosphatidylethanolamine, which are preferentially localized in the inner half of the membrane lipid bilayer, but this interaction is not well characterized. In the present study we used electron microscopy of rotary-shadowed platinum replicas of spectrin dimer-phosphatidylserine complexes to study the interaction of spectrin...
