Lipopolysaccharides (LPS) is an endotoxin derived from the outer leaflet of the outer membrane of Gram-negative bacteria. Lipopolysaccharides consists of an antigen O-specific chain, a core oligosaccharide and lipid A. Lipopolysaccharides is a pathogenic associated molecular pattern (PAMP) that activates the immune system. Lipopolysaccharides activates TLR-4 on immune cells[1][2][3]. This product is derived from Escherichia coli O55:B5.
Lipopolysaccharides (10-80 μg/mL) selectively decreases THir (tyrosine hydroxylase immunoreactive) cells and increases culture media levels of interleukin1β (IL-1β) and tumor necrosis factor-α (TNF-α) as well as nitrite (an index of nitric oxide (NO) production)[4].
Lipopolysaccharides (1.5 mg/kg; i.p.; once) induces sickness and hypothermia in mice, and induces a greater and more prolonged sickness response in adult male mice[3].
| Animal Model: | Female and male CD1 mice[3] |
| Dosage: | 1.5mg/kg |
| Administration: | Intraperitoneal injection, once |
| Result: | Induced sickness behavior in all mice, but adult mice displayed more sickness than pubertal mice and adult males remained sick for a longer period of time than adult females. Caused a decrease in body temperature for all mice, but this decrease was greatest in adult males. Increased pro- and anti-inflammatory cytokines at various levels in pubertal and adult male and female mice, resulted in age and sex differences in cytokine concentrations following immune challenge. Only adult males and females treated with LPS displayed significantly more IL-6 than their saline controls, and pubertal males and females and adult females displayed significantly more IL-10 than their saline controls. All the mice displayed significantly more IL-12 and TNF-α than their saline controls. |

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |

Step 2: Enter the in vivo formulation (This is only the calculator, not formulation. Please contact us first if there is no in vivo formulation at the solubility Section.)
Calculation results:
Working concentration: mg/ml;
Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )
Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.
Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
3. All of the above co-solvents are available for purchase on the GlpBio website.
