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

ScreenFect™A plus recommended protocol
*Quick protocols are listed in the instructions attached to the actual product. Please access from the following URL or QR code.
The one-step protocol for ScreenFect™A plus transfection is described in the upper part. The optimal DNA-to-reagent-ratio for efficient cell transfection stays constant at around 1 : 3 to 1 : 4 ( DNA 100 ng : ScreenFect™A plus reagent 0.1 μL = 1 : 1 ) and we recommend splitting cells when they reach 60% ~ 80% confluence to avoid contact inhibition of cell proliferation.
For details, please refer to the detailed information from the URL (https://screenfect.jp) or QR code at left. We also have free sample for evaluation, so please request from sample order form.
