生物活性

Bacitracin is a polypeptide antibiotic against staphylococcal and pathogenic protozoa infections. Bacitracin inhibits cell wall biosynthesis and permeability through binding to the undecaprenyl pyrophosphate. Bacitracin inhibits macromolecular synthesis. Bacitracin is also a protein disulfide isomerase (PDI) inhibitor.

性状

Solid

体外研究(In Vitro)

Bacitracin (64 μg/mL,24 h) 与粘菌素一起显示出对 S. aureus BA01611 的抗菌活性.
Bacitracin (64 μg/mL,1或2 h) 破坏细胞表面,使其形成葡萄状细胞团,使得细胞边界模糊不清。

产品不同,其溶解度不同。建议根据产品选择合适的溶剂配制储备溶液;配成溶液后,建议分装保存,避免反复冻融造成的产品失效
储备液的保存方式和期限:-80°C, 6 months; -20°C, 1 month (protect from light)。-80°C 储存时,建议在 6 个月内使用,-20°C 储存时,建议在 1 个月内使用。

体内研究:

建议根据您的实验动物和给药方式选择适当的溶解方案。以下溶解方案都建议先按照 体外研究 方式配制澄清的储备液,再依次添加助溶剂:

——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议您现用现配,当天使用; 以下溶剂前显示的百

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
