Analysis of Citric Acid (CA) by Enzyme-labeled Instrument (CAT#: STEM-MB-1435-LGZ)
Introduction
Sensitivity: 0.06 mmol/L
Detection range: 0.06-2.0 mmol/L
Precision: inter-lot difference of 4%, intra-lot difference of 4%
Detection equipment: Enzyme-labeled Instrument
Detection wavelength: 535-555 nm
Principle
Under acidic conditions, hexvalent chromium Cr(Ⅵ) is reduced to Cr3+, and the latter is complexed with citric acid. The product has a characteristic absorption peak at 545 nm. By measuring the increase of absorption value at 545 nm, the content of citric acid in the sample can be calculated.
Applications
It is suitable for the determination of citric acid in animal tissue samples, serum (plasma) and mitochondria.
Procedure
1. Prepare standard samples and experimental samples.
2. Add reaction reagents in order for reaction.
3. Measure the absorbance of each tube.
4. Make the mark curve and calculate the result.
