STANDARDS AND BUFFERS

Compatibilities between buffers and standards

Antioxidant Standards

Antioxidant capacity measure results are usually expressed as antioxidant equivalents. Bioquochem offers 3 different antioxidants, ascorbic acid (vitamin C), galic acid and TROLOX to compare e-BQC results (uC) to classical antioxidant capacity units: CEAC (vitamin C equivalents of antioxidant capacity), GAE (galic acid equivalents) and TEAC  (TROLOX equivalents of antioxidant capacity) respectively.

Similar to Assay Kits calibration, a calibration curve, with measures of increasing concentration solutions of this antioxidants would be needed for this transformation.

Intended useTo dilute samples of food and beverages, or antioxidant standards. Maintains the stability of the ascorbic acid in its natural conditions.To dilute, wash or resuspend biological samples of cell and tissue cultures, or antioxidant standards. It has similar physicochemical conditions as the human body, such as pH, osmolarity and ion concentrations.
To dilute samples with low requirements, or antioxidant standards.
