Technical Support

Guanine is one of the fundamental components of nucleic acids (DNA and RNA). Guanine is a purine derivative, consisting of a fused pyrimidine-imidazole ring system with conjugated double bonds. Guanine has the potential to serve as a large-capacity N pool. Guanine has cytotoxic, antinociceptive and neuroprotective effects.

Guanine (200-600 nmol; i.t.) produces A1 adenosine receptor-mediated antinociception against intraplantar glutamate-, Capsaicin (HY-10448)-, and Acetic acid (HY-Y0319)-induced pain in mice, with ID50 values of 107, 84, and 48 nmol and maximal inhibitions of 48%, 58%, and 56%, respectively^[4].
Guanine (200-600 nmol; i.t.) produces dose-dependent antinociception against tail-flick test thermal nociception in mice, with peak efficacy at 400 nmol yielding ~78% MPE^[4].
Guanine (200-600 nmol; i.t.) dose-dependently increases CSF levels of inosine, xanthine, and uric acid, with a significant increase in AMP at the highest dose^[4].

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
