體外研究
(In Vitro)

Temafloxacin (0-64 μg/mL; 18-24 h) shows good antibacterial activity for gram-positive/negative bacteria, with MIC ranges of <0.004-0.5, 0.5-2 and 0.06-0.25 μg/mL for E. coli, P. aeruginosa, and S. aureus, respectively[1].

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

Cell Viability Assay[1]

Cell Line: E. coli (16 strains), P. aeruginosa (13 strains), and S. aureus (17 strains).
Concentration: 0-64 μg/mL
Incubation Time: 18-24 h
Result: Inhibited E. coli (16 strains), P. aeruginosa, and S. aureus with MIC ranges of <0.004-0.5 (MIC 90%=0.06, =0.06), 0.5-2 (MIC 90%=1, MIC 50%=1) and 0.06-0.25 μg/mL (MIC 90%=0.125, MIC 50%=0.125). MIC 90% and 50% means MIC for 90% and 50% of the isolates (unit: μg/mL).

請(qǐng)根據(jù)您的 實(shí)驗(yàn)動(dòng)物和給藥方式 選擇適當(dāng)?shù)娜芙夥桨浮?

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分比是指該溶劑在您配制終溶液中的體積占比；如在配制過程中出現(xiàn)沉淀、析出現(xiàn)象，可以通過加熱和/或超聲的方式助溶

  • 方案 一

    請(qǐng)依序添加每種溶劑： 10% DMSO    90% Corn Oil

    Solubility: ≥ 0.5 mg/mL (1.20 mM); 澄清溶液

    此方案可獲得 ≥ 0.5 mg/mL（飽和度未知）的澄清溶液，此方案實(shí)驗(yàn)周期在半個(gè)月以上的動(dòng)物實(shí)驗(yàn)酌情使用。

    以 1 mL 工作液為例，取 100 μL 5.0 mg/mL 的澄清 DMSO 儲(chǔ)備液加到 900 μL玉米油中，混合均勻。

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.
