The product is not tested for microbial contamination. Instead, a fluorometric toxicity assay is conducted. This involves growing three mammalian cell lines in the presence of the test product. After 7 days of incubation, the fluorescence is measured, and it is directly proportional to cell density.

General description
(+)-Sodium L-ascorbate (SA) is a potential antioxidant and is a derivative of vitamin C (L-ascorbic acid).[1] It is widely used as a food additive. In addition, SA enhances growth retardation activity of bleomycin sulfate, R020-1724 (an inhibitor of cyclic nucleotide phosphodiesterase), prostaglandin E1 and sodium butyrate agents on neuroblastoma cells in culture. Elevated levels of SA induces two-stage urinary bladder carcinogenesis in rats. sodium L-ascorbate in combination with collagenogenesis inhibitors is used to treat dermal scars and keloids.[1]
Application
(+)-Sodium L-ascorbate has been used:
- to produce H2O2 in cell culture media
- as a reducing agent for a cell-permeable artificial electron donor, N,N,N′,N′-tetramethyl-p-phenylenediamine (TMPD)
- to study its effect on production of collagen and elastic fibers in fibroblasts cultures derived from normal human skin and dermal fat[1]
Used for preparation of plant extracts; reductant for the isolation of chloroplasts.
