产品使用指南 技术支持

D-Histidine (Standard) 是 D-Histidine (HY-W012572) 的分析标准品。本产品用于研究及分析应用。D-Histidine 是一种靶向细菌群体感应系统 (如 RhlI/RhlR 通路) 的抗生物膜生成试剂，具有抗菌活性。D-Histidine 通过非共价结合细菌调控因子或铜离子复合物发挥作用，选择性抑制细菌生物膜形成和运动性。D-Histidine 下调群体感应相关基因表达、减少毒力因子 (如藻酸盐、蛋白酶) 合成，以及干扰细菌膜稳定性，发挥抑制生物膜形成、促进成熟生物膜解体及增强抗生素敏感性的活性。D-Histidine 也是盐诱导肽形成 (SIPF) 反应的高效催化剂，通过与铜离子 (Cu2+) 形成复合物，促进氨基酸缩合生成二肽 (如二丙氨酸、二赖氨酸)。

生物活性

D-Histidine (Standard) is the analytical standard of D-Histidine (HY-W012572). This product is intended for research and analytical applications. D-Histidine is an anti-biofilm agent that targets bacterial quorum sensing systems (such as RhlI/RhlR pathway) and has antibacterial activity. D-Histidine works by non-covalently binding to bacterial regulatory factors or copper ion complexes, selectively inhibiting bacterial biofilm formation and motility. D-Histidine downregulates quorum sensing-related gene expression, reduces the synthesis of virulence factors (such as alginate and proteases), and interferes with bacterial membrane stability, inhibiting biofilm formation, promoting the disintegration of mature biofilms, and enhancing antibiotic sensitivity. D-Histidine is also an efficient catalyst for the salt-induced peptide formation (SIPF) reaction, which promotes the condensation of amino acids to form dipeptides (such as dialanine and dilysine) by forming a complex with copper ions (Cu2+).

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.
