一般描述
Sigma Universal Transfection Reagent is a unique formulation of a biodegradable, proprietary cationic polymer conjugated to a cationic lipid. Universal Transfection Reagent is used for transfection of nucleic acids into common eukaryotic cell lines. Fast and easy protocol is compatible with serum, serum-free medium and antibiotics. For most cells, medium change after transfection is not necessary.
应用
Suitable for transient and stable transfection of nucleic acids into cultured eukaryotic cells. Use approximately 1-3 μl Universal Transfection Reagent per μg DNA. Protocol optimization provides very efficient transfection. The following cells have been successfully transfected using Sigma Universal Transfection Reagent:

组分
Note the formulation of Sigma Universal Transfection Reagent is confidential.
原理
Sigma Universal Transfection Reagent is a cationic polymer conjugated to a cationic lipid. When mixed with plasmid DNA, the reagent forms stable complexes that can be directly added to the cell culture. The cells take up the complexes by endocytosis, the polymer is cleaved from the complex, and the plasmid DNA is quickly released into the cytoplasm.
其他说明
Complex formation is inhibited by serum, but once stable complexes have formed, the presence of serum lowers the toxicity of transfection.

Excessive inflammatory responses induced upon SARS-CoV-2 infection are associated with severe symptoms of COVID-19. Inflammasomes activated in response to SARS-CoV-2 infection are also associated with COVID-19 severity. Here, we show a distinct mechanism by which SARS-CoV-2 N protein promotes NLRP3
