In this study, bovine serum albumin-paclitaxel nanoparticles were prepared by high-pressure homogenization method with halogenated salt as coagulant. The effect of process parameters such albumin concentration, coagulant homogenisation time, pressure, water/ethanol ratio and was analyzed to optimize nanoparticle size, conversion rate encapsulation efficiency. Bovine concentration pressure found...

Albumin is the major plasma protein and its determination is used for the prognostic assessment of several diseases. Clinical guidelines call for monitoring of serum albumin with specific target cut-offs that are independent of the assay used. This requires accurate and equivalent results among different commercially available methods (i.e., result standardization) through a consistent definiti...

Abstract Interactions between pentacyclic triterpenes isolated from white birch (Betula pendula Roth.) bark samples Northeast Bulgaria and bovine serum albumin or human were investigated using fluorescence techniques. The experimental results show the formation of complexes with albumins. Quenching intrinsic albumins was monitored by emission spectra varied quencher concentration solutions. By ...

Metal binding strategies employing low molecular weight chelators and equilibrium dialysis were used to investigate several unresolved aspects of zinc and copper binding to serum albumin. Direct measurement of histidine binding to bovine serum albumin when the histidine is presented either as a metal-chelate or alone provides no evidence for an albumin-metal-histidine ternary complex. Using pre...

Glycylglycyiglycine was investigated as a reference standard for use in serum protein measurement by the biuret reaction. The tripeptide-biuret solution has a molar absorptivity of 96 at 565 nm, and absorbances at both 550 nm and 565 nm are proportional to concentration. By a manual reference procedure, the 550-nm absorbance of 1.0 g of tripeptide was equivalent to that given by 1.72 ± 0.03 g o...

The interactions of cefoperazone sodium with bovine transferrin and bovine serum albumin were studied by multi-spectroscopic methods. Results showed that the intrinsic fluorescence of proteins was quenched by the cefoperazone sodium with a static quenching procedure. The thermodynamics parameters indicated that electrostatic attraction played a major role in the interactions of drug and protein...

The fluorescence yield of bound retinol in human retinolbinding protein (RBP) and irs prealbumin complex (PARBP) were found to be nearly the same and to exceed that of free retinol in petroleum ether by about 9-fold. Bovine serum albumin and P-lactoglobulin also formed strongly fluorescent water-soluble complexes with retinol. The fluorescence yield of retinol complexed with bovine serum albumi...

The interaction of a dirhamnolipid biosurfactant secreted by Pseudomonas aeruginosa with bovine serum albumin was studied by means of various physical techniques. Binding of the biosurfactant to bovine serum albumin was first characterized by isothermal titration calorimetry, showing that one or two molecules of dirhamnolipid, in the monomer state, bound to one molecule of the protein with high...
