Intrument | Spectrophotometer(533 nm) |
Assay Time | 80 min |
Validity | 6 |
Assay Type | Quantitative |
Sample Type | Serum,plasma,tissue |
Synonyms | VC,Ascorbic acid |
Detection Principal | The most obvious chemical activity of VC is that reduce Fe3+ to Fe2+, then promote iron absorption in the intestine, promote the storage and utilization of iron. Fe3+ react immediately with reducing ascorbic acid to form Fe2+. then Fe2+ react with phenanthroline and the color developing reaction occurs. The content of vitamin C in sample can be determined. Measure the OD value and calculate the VC content indirectly. |
