Labeling of high density lipoproteins with [3H] acetic anhydride.
Rat serum HDL was labeled by reaction with [3H] acetic anhydride at pH 7.2 for 30 min at room temperature by a modification of the method of Montelaro and Rueckert (1975. J. Biol. Chem. 250: 1413). Protein specific activities of 60 dpm/ng were achieved. Seven percent of the label was in lipid, of which 92 percent was recovered in phospholipid. The labeled HDL migrated as a single band as seen b...
متن کاملMultivalent mannose-displaying nanoparticles constructed from poly{styrene-co-[(maleic anhydride)-alt-styrene]}.
Micellar mannose nanoparticles were constructed from poly{styrene-co-[(maleic anhydride)-alt-styrene]} with fluorophores or quenchers doped into the hydrophobic inner cores, allowing the direct monitoring of multivalent lectin-glycan interactions. The mannose-displaying nanoparticles bind Con A and sperm surface lectins with high affinity, suggesting their broad utility for modulating protein-c...
متن کاملModification of Sugarcane Bagasse with Acetic Anhydride and Butyric Anhydride in Ionic Liquid 1-butyl-3-methylimidazolium Chloride
Bagasse acetate butyrates were prepared homogeneously in 1-butyl-3methylimidazolium chloride ([C4mim]Cl) ionic liquid from ball-milled sugarcane bagasse by acylation with acetic anhydride and butyric anhydride. The parameters, including reaction temperature, reaction time, feeding method of adding anhydrides, the dosage of total anhydrides to SCB, and the molar ratio of acetic anhydride to buty...
متن کاملMorphologies and Thermal Variability of Patterned Polymer Films with Poly(styrene-co-maleic anhydride)
Patterned films of poly(styrene-co-maleic anhydride) copolymers were deposited by dip-coating from acetone solutions. A qualitative study of the film morphologies shows the formation of polymer spheres with smaller diameters at higher amounts of maleic anhydride (MA), and long-fibrous features at higher molecular weights. Upon heating, the films progressively re-assemble with shortand long-fibr...
متن کاملDissociation of single-stranded DNA from nucleosomes following modification with acetic anhydride.
Modification with acetic anhydride of nucleosomes from chicken erythrocytes at low ionic strength (less than 0.1 M NaCl) is accompanied by the formation of residual particles and the release of free DNA. This DNA has been identified as single-stranded by thermal denaturation, digestion with nuclease S1, and elution from hydroxyapatite. In contrast, if modification takes place at 0.6 M NaCl, the...
