生物活性
Polymyxin B1 is a potent antimicrobial lipopeptide first derived from Bacilus polymyxa. Polymyxin B1 is the major component in Polymyxin B (HY-A0248). Polymyxin B1 can induce lysis of bacterial cells through interaction with their membranes. Polymyxin B1 has the potential for multidrug-resistant Gram-negative bacterial infections treatment.

Solid
体外研究(In Vitro)
Polymyxin B1 has antimicrobial activity that againsts Pseudomonas aeruginosa ATCC 27853, Acinetobacter baumannii ATCC BAA 747, Klebsiella pneumoniae ATCC 13883, P. aeruginosa 9019, A. baumannii 1261 and K. pneumoniae VM9 isolates with MIC values of 4 μg/mL, 2 μg/mL, 2 μg/mL, 4 μg/mL, 4 μg/mL and 2 μg/mL, respectively.
Polymyxin B1 strongly inhibits protein synthesis in yeast, and in E. coli and S. aureus.Medlife has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究(In Vivo)
The pharmacokinetics of Polymyxin B1 is investigated in a rat model following intravenous administration (0.8 mg/kg). The area under the concentration-time curve for Polymyxins B1 is greater than those of colistins A and B. Colistin A colistin B. The clearance value of Polymyxins B1 is 2.39 mL/min/kg, the plasma protein binding is 82.3%, the elimination half-life is 79.5 min and the AUC0-∞is 365 mg?min/L.Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

1:一般建议:溶解度为Medlife测试数据,可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异,仅做参考,具体以实验方案为准。

2:储存条件:粉末-20°C一般情况可以保存3年,溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异,请细致阅读产品信息,并辅助参考相关文献描述。

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
