Uric acid. Characterization of its interaction with human serum albumin.
Binding of sodium urate to human serum albumin (HSA) was measured by continuous ultrafiltration at pH 7.4 and ionic strength 0.16 over the concentration range 1-13 mg/100 ml. The percent sodium urate bound to 5 g/100 ml HSA was constant over this concentration range: 30.3 (SE+/-0.6)% being bound at 4 degrees C, 22.6+/-0.3% at 22.5 degrees C, and 19.6+/-0.3% at 37 degrees C. Derived association ...
متن کاملVoltammetric determination of DNA based on its interaction with neutral red
A new linear sweep vo ltammetric (LSV) assay of fsDNA based on its interaction with neutra l red (N R) is presented. At pH 8.0 Britton-Robinson (8-R) buffe r solutio n, the dye can bind with DNA to form a supramolec ular complex , wh ich results in the decrease of the linear sweep voltammetric reductive peak current at -0.60 V (vs. SCE) on the mercury e lec trode. The binding reaction is comple...
متن کاملVoltammetric Determination of Heparin Based on Its Interaction with Malachite Green
In this paper malachite green (MG) was used as a bioprobe to determine heparin concentration by linear sweep voltammetry on the dropping mercury working electrode (DME). In Britton-Robinson (B-R) buffer solution of pH 1.5, MG had a well-defined second order derivative linear sweep voltammetric reductive peak at –0.618 V (vs. SCE). After the addition of heparin into the MG solution, the reductiv...
متن کاملInteraction of Phthalocyanine with Egg albumin and Bovine serum albumin
The interaction of bovine serum albumin ( BSA) and egg albumin with water solublephthalocyanine, cobalt (ΙΙ) 4, 4′ , 4′′, 4′′′- tetrasulfophthalocyanine ( CoTSPc) , has been studiedby the UV- Vis method at pH 7.0 and five different temperatures 20, 25, 30, 35 and 40°C. Theformation constants have been elucidated by using spectrophotometric titration and computerSQUAD program data refinement. Th...
