Neomycin sulfate 是一種氨基糖苷類(lèi)抗素,通過(guò)核 30S 核糖體亞單位的不可逆結(jié)合發(fā)揮抗菌活性 (antibacterial),從而阻斷細(xì)菌蛋白質(zhì)的合成。Neomycin sulfate 是一種已知的磷脂酶C (PLC) 抑制劑。Neomycin sulfate 能抑制血管生成素的核轉(zhuǎn)位和血管生成素誘導(dǎo)的細(xì)胞增殖和血管生成。
生物活性
Neomycin sulfate, an aminoglycoside antibiotic, exerts antibacterial activity through irreversible binding of the nuclear 30S ribosomal subunit, thereby blocking bacterial protein synthesis. Neomycin sulfate is a known phospholipase C (PLC) inhibitor. Neomycin sulfate potently inhibits both nuclear translocation of angiogenin and angiogenin-induced cell proliferation and angiogenesis[1][2].
體外研究(In Vitro)
Neomycin is effective against most gram-negative organisms except Pseudomonas aeruginosa and anaerobic bacteria. Its activity against gram-positive microorganisms is more or less limited to staphylococci, but bacterial resistance supervenes after prolonged use[1].

請(qǐng)根據(jù)產(chǎn)品在不同溶劑中的溶解度選擇合適的溶劑配制儲(chǔ)備液;一旦配成溶液,請(qǐng)分裝保存,避免反復(fù)凍融造成的產(chǎn)品失效。
儲(chǔ)備液的保存方式和期限:-80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture)。-80°C 儲(chǔ)存時(shí),請(qǐng)?jiān)?6 個(gè)月內(nèi)使用,-20°C 儲(chǔ)存時(shí),請(qǐng)?jiān)?1 個(gè)月內(nèi)使用。
以下溶解方案都請(qǐng)先按照 In Vitro 方式配制澄清的儲(chǔ)備液,再依次添加助溶劑:
——為保證實(shí)驗(yàn)結(jié)果的可靠性,澄清的儲(chǔ)備液可以根據(jù)儲(chǔ)存條件,適當(dāng)保存;體內(nèi)實(shí)驗(yàn)的工作液,建議您現(xiàn)用現(xiàn)配,當(dāng)天使用; 以下溶劑前顯示的百
