目录号: HY-D1056B1
产品使用指南 技术支持

Lipopolysaccharides, from Proteus vulgaris 是来源于普通变形杆菌 (Proteus vulgaris) 的脂多糖内毒素和 TLR-4 激活剂，是 S 型 LPS，可激活免疫系统的致病相关分子模式 (PAMP) 和诱导细胞分泌迁移体。Lipopolysaccharides, from Proteus vulgaris 具有典型的 3 部分结构：O 抗原、核心寡糖和脂质 A。Lipopolysaccharides, from Proteus vulgaris 具有独特的分子结构和壳聚糖亲和力 (Kb=2.72 μM)，好于假结核耶尔森菌 (Kb=6.06 μM) 和大肠杆菌 (Kb=79.50 μM)。
建议配制 ≥2 mg/mL 母液，并保证充分混合溶解。由于 LPS 具有吸附特性，分装保存时需使用低吸附离心管。

生物活性

Lipopolysaccharides, from Proteus vulgaris are lipopolysaccharide endotoxins and TLR-4 activators derived from Proteus vulgaris, classified as S-type LPS, which can activate pathogen-associated molecular patterns (PAMP) of the immune system and induce cellular secretion of migrasomes. Lipopolysaccharides, from Proteus vulgaris exhibit a typical three-part structure: O-antigen, core oligosaccharide, and lipid A. Lipopolysaccharides, from Proteus vulgaris possess a unique molecular structure and chitosan affinity (Kb=2.72 μM), surpassing that of Yersinia pseudotuberculosis (Kb=6.06 μM) and Escherichia coli (Kb=79.50 μM)[1].
It is recommended to prepare a stock solution of ≥2 mg/mL and ensure that it is fully mixed and dissolved. Due to the adsorption characteristics of LPS, low adsorption centrifuge tubes should be used for aliquoting and storage.

Note:
1. 为了保持 LPS 的完整性，建议将 LPS 溶液存放在硅烷化容器中。因为 LPS 可以粘附在塑料和某些类型的玻璃上，尤其是在浓度低于 0.1 mg/mL 时。如果 LPS 浓度超过 1 mg/mL，这种吸附作用相对较小，建议配制 ≥2 mg/mL 母液，并充分涡旋震荡 10 分钟以上，必要时辅助超声，保证充分混合溶解。如果使用玻璃容器，请确保使用前充分混合至少 30 分钟，以重新溶解任何吸附在管壁的 LPS。
2. LPS 是一种能在溶液中形成不同尺寸胶束的分子，分子量不固定，储备液及工作液可直接配制成质量浓度 (mg/mL, μg/mL, etc.)。
3. LPS 溶于水或 PBS 后可能会观察到均匀的浑浊溶液，如需过滤除菌，请勿直接过滤储备液，建议稀释成工作液之后用 0.22 μm 的滤膜过滤除菌。

Lipopolysaccharides, from Proteus vulgaris (200 μg/mL；2 h) 经过与壳聚糖孵育后，生成具有高粒径分布度和多分散性的复合物[1]。

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.
