Fluoride affects Coomassie Brilliant Blue measurement of protein in cerebrospinal fluid

Total protein determined in human breast milk by use of coomassie brilliant blue and centrifugal analysis.

This simple method of centrifugal analysis for total protein in human breast milk is based on the change in the wavelength of the absorbance maximum of Coomassie Brilliant Blue G-250 when the dye is bound to protein. Within-run and between-day CVs were 3.8% and 4.8%, respectively. Compared with a micro-Kjeldahl method for determination of total nitrogen, the coefficient of correlation was 0.99.

Self-oligomerization and protein aggregation of alpha-synuclein in the presence of Coomassie Brilliant Blue.

alpha-Synuclein has been implicated in various neurodegenerative disorders, including Parkinson's and Alzheimer's diseases, by its participation in abnormal protein depositions. As the protein has been suggested to play a significant role in the formation of the deposits which might be responsible for neurodegeneration, there is a strong demand to screen for alpha-synuclein-interactive small mo...

Threshold of pathological proteinuria measured with Coomassie Brilliant Blue.

Binding of bioactive coomassie brilliant blue G with protein: Insights from spectroscopic studies

The binding of CBB to BSA was investigated under imitated physiological conditions employing different optical spectroscopic techniques viz., fluorescence emission, UV-vis absorption and FTIR. Fluorescence quenching data obtained at different temperatures suggested the presence of dynamic type of quenching mechanism. The values of K and n for CBB-BSA system were calculated and found to be 4.20 ...

Evaluation of the Coomassie Brilliant Blue G-250 method for urinary protein.

The Coomassie Brilliant Blue G-250 method for protein in urine has been evaluated for analytical accuracy and clinical applicability. Extremely simple to perform, the test exhibits good precision and sensitivity. The color developed per gram of protein is protein-type dependent, so no single protein standard is completely satisfactory. Color intensity is linearly related to concentration up to ...
