A New liposome developed by click chemistry!!

ScreenFect™A is a transfection reagent consisting of a new cationic liposome screened*1 by click chemistry. It can be used with various eukaryote-derived cells and can be added directly to mediums containing antibiotics or serum. DNA and siRNA can be transfected into general experimental cell strains (HeLa, HepG2, MDCK, Cos-7, etc.), stem cells (mouse ES cells, etc.), blood cells (macrophages, THP-1, RAW264, 7, etc.), microglia, primary (initial subculture) cells, and Insect cell. Medium replacement after transfection is not required due to low cytotoxicity. The constituent reagents do not contain any poisonous or deleterious substance.

  • High transfection efficiency and low cytotoxicity
  • Can be used for both DNA and siRNA
  • No need to exchange medium and can be used in the presence of serum

In comparison with competitor

Transfection data

Low cytotoxicity

images

GFP-expressing plasmid DNA was transfected into HEK293 cells using ScreenFect™A. The results demonstrated gene transfection efficiency is equal or superior to competitors. Cytotoxicity was also comparable to competitors. (96-well plate, GFP-expressing plasmid DNA 75 ng/well)

Gene transfection into mouse ES cells

images

GFP-expressing plasmid DNA was transfected into mouse ES cells using ScreenFect™A and GFP-positive cells were detected. As a result, about 60% or more of mouse ES cells were GFP-positive cells.

Also applicable to gene transfection into stem cells!

 

siRNA transfection

images

LRP6 siRNA was transfected into HEK293 cells using ScreenFect™A. It showed that a higher knockdown efficiency than the Company A and the Company B. (96-well plate, final concentration of 1 pmole LRP6 siRNA at 2 nM/well)

images

GAPDH siRNA was transfected into each cell line using ScreenFect™A. The results demonstrated that a higher knockdown efficiency than competitor. (96-well plate, final concentration of GAPDH siRNA at 3 nM/well)
