N-tetradecanoyl-L-Homoserine lactone

产品编号 T37747 CAS 202284-87-5

别名: C14-HSL, tDHL, N-tetradecanoyl-L-Homoserine lactone

Quorum sensing is a regulatory system used by bacteria for controlling gene expression in response to increasing cell density. Controlling bacterial infections by quenching their quorum sensing systems is a promising field of study. The expression of specific target genes, such as transcriptional regulators belonging to the LuxR family of proteins, is coordinated by the synthesis of diffusible acylhomoserine lactone (AHL) molecules. N-tetradecanoyl-L-Homoserine lactone (C14-HSL) is a small diffusible signaling molecule involved in quorum sensing, thereby controlling gene expression and affecting cellular metabolism in bacteria.[1],[2],[3] It appears later than shorter acyl chain AHLs in developing biofilms[4] and, like other long chain AHLs, stimulates bacterial growth.[5] C14-HSL also alters the proteolytic activity and enhances the migration of some strains of Proteus mirabilis.[6]

体内实验配液计算器

请在以下方框中输入您的动物实验信息后点击计算，可以得到母液配置方法和体内配方的制备方法：比如您的给药剂量是10 mg/kg，每只动物体重20 g，给药体积100 μL，一共给药动物10 只，您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。

母液配置方法：2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL)，如您需要配置的浓度超过该产品的溶解度，请先与我们联系。

体内配方的制备方法：取 50 μL DMSO 主液，加入 300 μL PEG300，混匀澄清，再加 50 μL Tween 80，混匀澄清，再加 600 μL ddH2O, 混匀澄清。
