Reaction products are detected by a colorimetric method after adsorption of the resulting DNA duplexes to the solid phase.
In addition, the malondiadehyde (MDA) was quantitated by the thiobarbituric acid procedure and the total antioxidative capability (T-AOC) by a colorimetric method.
Furthermore, enzymes could also be immobilized on the residual bare surfaces of amyloid-GO, and served by a colorimetric method for a sensitive and selective analytical glucose-detecting platform.
Enzymatic activities of acetylcholinesterase (AChE) and superoxide dismutase (SOD) were evaluated from hippocampus and plasma samples, and malondialdehyde (MDA), which is the end-product of lipid peroxidation, was determined by a colorimetric method.
Total flavonoid content of the plant extracts was determined by a colorimetric method [37].
The total carbohydrate content was analyzed by a colorimetric method using anthrone reagent (Updegraff [1969]).
Vitamin C was determined by a colorimetric method of Zhang et al. ([2009]), with modifications.
Total flavonoid content was estimated by a colorimetric method reported by Barros et al. ([2007]).
The free radical-scavenging activity of the extracts was determined by a colorimetric method, using the stable DPPH radical [21].
NO production was indirectly assessed by measuring the nitrite levels in BALF determined by a colorimetric method based on the Griess reaction (Shie et al. 2015).
