The Lonza 4D-Nucleofector platform has multiple electroporation volume and vessel options. Most recent answer. To detect on-target mutations and estimate editing efficiency, we Note: The unused wells from the strip can be used for another experiment. Understanding Bubbles: Of course you do the bench tap to minimize those bubbles, but it's a good idea to have in the back of your mind what the reason is. The Lonza system allows electroporation in different volumes (e.g., 20 L or 100 L), and previous literature have optimized the electroporation parameters for each cell line. Electroporation Buffer, supplied by Lonza, used in various techniques. Turn on the 4D-Nucleofector System. 3. . Mix gently each sample and transfer 25 L in a free well of the 16-well electroporation strip (Lonza). In the area of stem cell research, we will highlight current gene transfer methods into adult and embryonic stem cells and discuss the use of mRNA electroporation for . Protocol 1: standard. Electroporation is an electro-physical, non-viral approach to perform DNA, RNA, and protein transfections of cells. Electroporate the cells, recover the strip and turn off the instrument. at 750xg for 20 minutes at 20 C in a swinging-bucket rotor without brake 1.6 Remove the upper layer leaving the mononuclear cell layer undisturbed at the interphase.

Approximately 18-24 hours before electroporation, passage cells to attain an optimal cell density at the time of electroporation (i.e. Jun Cui. LUCIFERASE ACTIVITY MEASUREMENT 12 Break cells by beatbeater: 75-150 m glass beads, 4800g (max), 1 min 13 Centrifuge at maximum speed. TYPICAL RESULTS . Place SOC recovery medium in a 37C water bath. Cells were electroporated with an EGFP reporter vector in parallel, using the BTX ECM 830 Square Wave Electroporator with the BTXpress High Performance Electroporation Solution or using the Amaxa (Lonza) system. This is particularly useful for transfecting pRPa constructs, which integrate at the 'landing pad locus' in 2T1 cells, or . Use 30 l of lysis buffer as blank sample. Evaluation of Cas9-RNP system: Primary human NK cells (isolated and rested overnight) and human NK cell . Electroporation has emerged as a powerful tool for the genetic modification of diverse cell types [13] - [15]. For instance, the Lonza 96-well Shuttle Device is an optional add-on to the 4D-Nucleofector, enabling up to 96 independent programs to run simultaneously. Bioz Stars score: 86/100, based on 40 PubMed citations. Glycerol Impurities: This doesn't happen often, but it's possible that impurities in glycerol raise the conductivity and cause your electroporation to arc. Post Nucleofection 3.1 Incubate the diluted E. coli at 37C for expression of the resistance marker (e.g. Determine the number of cells needed for the study, and collect the desired number of cells from the culture flask into a 50 mL tube. a. Prepare 6-well plates with 1 mL Geltrex/DMEM-F12 or 2104 cells/cm 2 MEF-feeder (see steps 24-41).
