产品使用指南

Frequentin 是由青霉菌产生的次级代谢产物,受环境条件(例如硝酸镉和氯化钠浓度)的影响。在无硝酸镉的培养基中,P. janthinellum 会产生环青霉素、卡洛西酸、红霉素、曲酸和棒曲霉素。在 100 ppm 硝酸镉下,它会产生环青霉素、卡洛西酸、frequentin 和 islandicin。在氯化钠存在下,frequentin 的浓度为 2% 和 3%。这些发现表明,frequentin 的产生对特定的环境压力源很敏感,突出了其在不同生长条件下的潜在变化。

生物活性

Frequentin, a secondary metabolite produced by Penicillium janthinellum, is influenced by environmental conditions such as cadmium nitrate and sodium chloride concentrations. In cadmium nitrate-free medium, P. janthinellum produces cyclopenin, carlosic acid, erythroskyrin, kojic acid, and patulin. At 100 ppm cadmium nitrate, it produces cyclopenin, carlosic acid, frequentin, and islandicin. In the presence of sodium chloride, frequentin is produced at 2% and 3% concentrations. These findings indicate that frequentin production is sensitive to specific environmental stressors, highlighting its potential variability under different growth conditions[1].

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.
