COA 產(chǎn)品使用指南

N-Acetylneuraminic acid (NANA; Lactaminic acid) 是一種非酚類結(jié)構(gòu),是結(jié)腸中唾液酸的主要形式。N-Acetylneuraminic acid 在心肌損傷、黑色素瘤和病毒或細(xì)菌感染中起生物學(xué)作用。N-Acetylneuraminic acid 通過降低酪氨酸酶活性抑制黑色素生成,并通過與 RhoACdc42 結(jié)合激活 Rho/Rho 相關(guān)信號通路,引發(fā)體外和體內(nèi)心肌損傷。N-Acetylneuraminic acid 可能預(yù)防高脂肪飲食 (HFD) 引起的炎癥和氧化應(yīng)激,從而預(yù)防高脂血癥相關(guān)的炎癥和氧化應(yīng)激。N-Acetylneuraminic acid 有望用于黑色素瘤,冠狀動脈,肥胖相關(guān)的疾病和高脂血癥領(lǐng)域的研究。

生物活性

N-Acetylneuraminic acid (NANA; Lactaminic acid), a nonphenolic structure, is the predominant form of sialic from Collocalia esculenta. N-Acetylneuraminic acid plays a biological role in myocardial injury, melanoma and viral or bacterial infection. N-Acetylneuraminic acid inhibits melanogenesis by reducing tyrosinase activity and triggers myocardial injury in vitro and in vivo by activation of the Rho/Rho-associated signaling pathway through binding to RhoA and Cdc42. N-Acetylneuraminic acid may prevent high fat diet (HFD)-induced inflammation and oxidative stress, thereby prevents hyperlipidemia-associated inflammation and oxidative stress. N-Acetylneuraminic acid is promising for research in the field of melanoma, coronary artery, obesity-related diseases and hyperlipidemia[1][2][3][4][5].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Healthy rats[2]
Dosage: 0 - 20 mg/kg
Administration: i.p., twice a day for 6 weeks

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.
