On the LE+\/EX+ model machines, we can use the PBMC mode to electroporate RNP into PBMCs with a high voltage. Stimulated T cells are electroporated at 2-3 days of stimulation time and the voltage is similar to common cell lines, much lower than the voltage of PBMCs. For example, we can knock out the TCR using 2-3 day stimulated T cells and the efficiency of knockout is 92% and cell growth is not impaired.<\/p><p><img fetchpriority=\"high\" decoding=\"async\" class=\"aligncenter\" style=\"color: var( --e-global-color-text ); font-family: var( --e-global-typography-text-font-family ), Sans-serif; font-size: var( --e-global-typography-text-font-size ); font-weight: var( --e-global-typography-text-font-weight );\" src=\"https:\/\/www.celetrix.com\/wp-content\/uploads\/2022\/01\/CD3%E6%95%B0%E6%8D%AE.png\"  width=\"667\" height=\"345\" title=\"Genome Editing\u63d2\u56fe\" alt=\"Genome Editing\u63d2\u56fe\" \/><\/p><p>T cell, NK cell and CD34+ HSC cells are important for gene and cell therapy applications.

RNP electroporation can achieve high efficiency gene editing in iPSCs, as shown with AAVS1 and OCT4 genes. One easy way to achieve high gene editing efficiency is to use relatively high concentration of RNP, such as 10 ug Cas9 and 5 ug gRNA in a 20 ul electroporation.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-8aa837c elementor-widget elementor-widget-text-editor\" data-id=\"8aa837c\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div><p><img decoding=\"async\" class=\"aligncenter\" style=\"color: var( --e-global-color-text ); font-family: var( --e-global-typography-text-font-family ), Sans-serif; font-size: var( --e-global-typography-text-font-size ); font-weight: var( --e-global-typography-text-font-weight );\" src=\"https:\/\/www.celetrix.com\/wp-content\/uploads\/2022\/01\/%E5%9B%BE%E7%89%873-1.png\"  width=\"764\" height=\"278\" title=\"Genome Editing\u63d2\u56fe1\" alt=\"Genome Editing\u63d2\u56fe1\" \/><\/p><p>Plasmid based gene editing is suitable for cell lines. The cell toxicity of large plasmids containing Cas9 gene and gRNA gene can be tolerated by cell lines. The gene editing efficiency from plasmid electroporation is usually lower than the efficiency from RNP electroporation. However, we can use drug resistant gene selection to improve the gene editing efficiency. For example, THP-1 cells was electroporated with a plasmid containing Cas9, gRNA, GFP and puromycin-resistance genes and cells were all positive in GFP after puromycin selection, with a high rate of gene editing.<\/p><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-a3f432f elementor-widget elementor-widget-text-editor\" data-id=\"a3f432f\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><img decoding=\"async\" class=\"alignnone size-full wp-image-595 aligncenter\" src=\"https:\/\/www.celetrix.com\/wp-content\/uploads\/2022\/01\/\u56fe\u72474.png\"  width=\"331\" height=\"156\" srcset=\"https:\/\/www.celetrix.com\/wp-content\/uploads\/2022\/01\/\u56fe\u72474.png 331w, https:\/\/www.celetrix.com\/wp-content\/uploads\/2022\/01\/\u56fe\u72474-300x141.png 300w, https:\/\/www.celetrix.com\/wp-content\/uploads\/2022\/01\/\u56fe\u72474-18x8.png 18w\" sizes=\"(max-width: 331px) 100vw, 331px\" title=\"Genome Editing\u63d2\u56fe2\" alt=\"Genome Editing\u63d2\u56fe2\" \/><\/p><p>Normally it takes long time to do gene editing with plasmids. We have developed protocols to perform quick gene editing, even with plasmids. Because of the high cell viability and efficiency of Celetrix electroporation, drug selection can be done for a short period at the transient transfection stage and the remaining cells carry gene editing without stable integration of the plasmid. This new method speeds up plasmid based gene editing and allows sequential editing of multiple genes.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-107fb73e\" data-id=\"107fb73e\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-21740019 elementor-nav-menu__align-start elementor-nav-menu--dropdown-none elementor-widget elementor-widget-nav-menu\" data-id=\"21740019\" data-element_type=\"widget\" data-settings=\"{&quot;layout&quot;:&quot;vertical&quot;,&quot;submenu_icon&quot;:{&quot;value&quot;:&quot;&lt;i class=\\&quot;fas fa-caret-down\\&quot; aria-hidden=\\&quot;true\\&quot;&gt;&lt;\\\/i&gt;&quot;,&quot;library&quot;:&quot;fa-solid&quot;}}\" data-widget_type=\"nav-menu.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t<nav aria-label=\"Menu\" class=\"elementor-nav-menu--main elementor-nav-menu__container elementor-nav-menu--layout-vertical e--pointer-background e--animation-fade\">\n\t\t\t\t<ul id=\"menu-1-21740019\" class=\"elementor-nav-menu sm-vertical\"><li class=\"menu-item menu-item-type-post_type menu-item-object-page menu-item-287\"><a href=\"https:\/\/www.celetrix.com\/zh\/genome-editing\/\" class=\"elementor-item\">Genome Editing<\/a><\/li>\n<li class=\"menu-item menu-item-type-post_type menu-item-object-page menu-item-285\"><a href=\"https:\/\/www.celetrix.com\/zh\/antibody-production\/\" class=\"elementor-item\">Antibody production<\/a><\/li>\n<li class=\"menu-item menu-item-type-post_type menu-item-object-page menu-item-288\"><a href=\"https:\/\/www.celetrix.com\/zh\/stem-cell-therapy\/\" class=\"elementor-item\">Stem cell therapy<\/a><\/li>\n<li class=\"menu-item menu-item-type-post_type menu-item-object-page menu-item-286\"><a href=\"https:\/\/www.celetrix.com\/zh\/car-tcar-nk\/\" class=\"elementor-item\">CAR-T&#038;CAR-NK<\/a><\/li>\n<\/ul>\t\t\t<\/nav>\n\t\t\t\t\t\t<nav class=\"elementor-nav-menu--dropdown elementor-nav-menu__container\" aria-hidden=\"true\">\n\t\t\t\t<ul id=\"menu-2-21740019\" class=\"elementor-nav-menu sm-vertical\"><li class=\"menu-item menu-item-type-post_type menu-item-object-page menu-item-287\"><a href=\"https:\/\/www.celetrix.com\/zh\/genome-editing\/\" class=\"elementor-item\" tabindex=\"-1\">Genome Editing<\/a><\/li>\n<li class=\"menu-item menu-item-type-post_type menu-item-object-page menu-item-285\"><a href=\"https:\/\/www.celetrix.com\/zh\/antibody-production\/\" class=\"elementor-item\" tabindex=\"-1\">Antibody production<\/a><\/li>\n<li class=\"menu-item menu-item-type-post_type menu-item-object-page menu-item-288\"><a href=\"https:\/\/www.celetrix.com\/zh\/stem-cell-therapy\/\" class=\"elementor-item\" tabindex=\"-1\">Stem cell therapy<\/a><\/li>\n<li class=\"menu-item menu-item-type-post_type menu-item-object-page menu-item-286\"><a href=\"https:\/\/www.celetrix.com\/zh\/car-tcar-nk\/\" class=\"elementor-item\" tabindex=\"-1\">CAR-T&#038;CAR-NK<\/a><\/li>\n<\/ul>\t\t\t<\/nav>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"<p>Electroporation by Celetrix Page Genome editing by CRISPR\/Cas9 With Celetrix electroporation, we can deliver\u00a0 RNP (ribonucleoprotein complex containing Cas9 protein and gRNA) or Cas9\/gRNA plasmid into cells to perform gene editing.
