Product Description


Product introduction:

 

Lipopolysaccharides, LPS for short, is a unique component in the cell wall of Gram-negative bacteria, located in the outermost layer of the cell wall. Structurally, LPS is composed of lipid A, core polysaccharides and O-polysaccharide side chains. Lipid A is the main component of bacterial endotoxin. LPS is difficult to fall off from the cell wall. When bacteria die, they fall off by dissolving and destroying cells. LPS can cause a cascade of immune stimulation and toxic pathophysiological activities of the body, and has a toxic effect on animal cells. LPS is also called endotoxin due to its non-secreted toxin properties in bacteria.

 

This product is derived from the serotype Escherichia coli O55:B5.

Storage and transportation

Transport in wet ice; store at 4°C, valid for 2 years.

 

Instructions:

 

 

LPS powder is non-sterile and needs to be filtered and sterilized when used in cell culture animal experiments. You can first dissolve the LPS powder in a balanced salt solution to prepare a high-concentration (for example, 1 mg/mL) storage solution. After sterilization by 0.22 μm filter, the LPS powder can be divided into small aliquots, which can be stored stably at -20°C for at least 12 months. Avoid repeated freezing and thawing. When using, dilute with balanced salt solution or culture medium to the required working solution concentration.

 

Notes:

 

1. LPS can be adsorbed on plastic or some glassware, especially when the concentration is lower than 0.1 mg/mL, so be careful when diluting the working fluid. When the LPS concentration is greater than 1 mg/mL, the above-mentioned adsorption effect is negligible.

2. For your safety and health, please wear lab coats and disposable gloves for operation.
