Application

Hypoxanthine is a nutrient additive for a variety of cell culture applications involving bacterial, parasite (Plasmodium falciparum) and animal cells. Hypoxanthine is a component of selection media used in hybridoma technologies.
Hypoxanthine has been used:
  • to gavage mice and to evaluate the activity of xanthine oxidase (XO) in pasteurized whole milk in vivo in potassium oxonate (PO) -induced mouse model of hyperuricemia
  • as a supplement in Iscove′s modified Dulbecco′s medium (IMDM) medium to cultivate in-vitro cell line (EL-1 cells)
  • as a pure standard for the quantification of hypoxanthine in vitreous fluid sample using high-performance liquid chromatography-ultra-violet (HPLC-UV) for the estimation of post-mortem interval

Biochem/physiol Actions

Hypoxanthine acts as an intermediate in purine metabolism. It elicits a vital role as a 5′-base of the anticodon in a few transfer-RNAs. Though similar to guanine (Gua), it is devoid of the exocyclic amino group at C(2) position. It may be used as a substrate to study the specificity and kinetics of hypoxanthine-guanine phosphoribosyl transferases.

Uric Acid in Cell Culture

Uric acid is not a direct additive to any of the classical cell culture media. However, it is present in animal sera. Consequently, uric acid is typically present in complete serum-supplemented classical cell culture systems.

HPLC Analysis of Xanthines on Purospher® STAR RP-18 endcapped

Xanthine is a purine base found in most human body tissues and fluids as well as in other organisms. Methylated xanthines (methylxanthines), which include caffeine, paraxanthine, theobromine, and theophylline, commonly used for their effects as mild stiµlants and as bronchodilators, notably in the treatment of asthma symptoms. This application shows the efficient separation of several common xanthines and may be applied their analysis in any number of desired matrices.
