Analysis of Vitamin E (VE) by Enzyme-labeled Instrument (CAT#: STEM-MB-1402-LGZ)

Vitamin E, in the presence of phenanthroline, reduces ferric ions to ferric ions, which under certain circumstances can form pink complexes with phenanthroline, with a maximum absorption wavelength at 533 nm. Vitamin E content can be calculated by colorimetry.

It is suitable for the determination of vitamin E(VE) in animal serum (plasma), animal and plant tissues.

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.

• Sample Type: serum, plasma, animal and plant tissues
