Jun 14, 2017 · The erythrocyte membrane can be used as a cloak containing >3,000 nanosponges. Once they are fully loaded with toxins, nanosponges are safely disposed of by the liver with low toxicity. Therefore, nanosponges are designed to work with any type of cancer or poisoning that exhibits dysregulation of, or abnormalities in, cellular membranes. Lipofectamine® 3000 reagent maintains a high transfection efficiency within a robust dynamic range of lipid doses for quick and easy optimization. A low toxicity lipid dose (0.75 µL for 24-well plates) is suggested for applications requiring minimal disruption of the cells. Enable High Transfection Efficiency in Novel Genome Editing ApplicationsI use 2.5ul of Lipofectamine 3000 for each 1ug of plasmid each in 50ul optiMEM incubate for 20 min at room temp, then add to 1^6 of HEK293cells that plated in DMEM supplemented with 10% FCS, 48...

I use lipofectamine 3000 to transfect Hek 293 cells in 6 wells plates. For the last transfection, I transfected at 60% confluency. Also, I used 2500 ng of DNA per well, 5µl of P3000 per DNA, 5µl ... Oct 11, 2015 · Transfection using Lipofectamine 3000 was performed according to the manufacturer's protocol with a DNA to Lipofectamine ratio of 1: 3 w/v. A transfection enhancer, the 3000 enhancer reagent (1 : 2, DNA : Reagent, w/v), was used along with the Lipofectamine 3000 transfection reagent for all transfections.
Innovative culture characteristics
Upon optimization of transfection conditions, we observed 85, 75 or 55 % genome editing efficiencies in HEK293FT cells, mouse ES cells, or human iPSCs, respectively. Furthermore, we were able to co-deliver donor DNA with Cas9 RNPs into a disrupted EmGFP stable cell line, resulting in the generation of up to 17 % EmGFP-positive cells. 2.1.1. Optimization of SSLNPs for siRNA Delivery . Lipid-Z (detail on the lipid synthesis is provided under experimental section) was prepared, purified and characterized by reversed-phase high-performance liquid chromatography (RP-HPLC) and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) ().
