Axiogenesis has now launched the Cor.4U<sup>\u00ae<\/sup>\u00a0human iPS cell-derived cardiomyocyte product line for use in testing the efficacy and safety of pharmaceutical therapies. The ability to characterize the ion channel profile of these cells and reliably record action potentials at a reasonable throughput is essential to fully realise the potential of this kind of product line. Building on the success of Cor. At<sup>\u00ae<\/sup>\u00a0mouse embryonic stem (ES) cell-derived cardiomyocytes on the Patchliner, Cor.4U<sup>\u00ae<\/sup>\u00a0human iPS cell-derived cardiomyocytes have now been characterized on the Patchliner in the voltage and current clamp modes. In this Application Note we present data using an 8-channel Patchliner characterizing Cor.4U<sup>\u00ae<\/sup>\u00a0cells. In the voltage clamp mode, voltage-dependent Na<sup>+<\/sup>\u00a0(NaV), K<sup>+<\/sup>\u00a0(KV) and hERG (an inward current using a high K<sup>+<\/sup>-containing external solution) channel currents were recorded (Fig. 1). When the Ca<sup>2+<\/sup>\u00a0channel agonist BayK 8644 was used a voltage-gated Ca<sup>2+<\/sup>\u00a0(CaV) current could be recorded. As expected, action potentials could be elicited in the current clamp mode. The effect of the compounds TTX and BayK 8644 on the action potentials evoked in Cor.4U cells is also shown.<\/p>\n","protected":false},"featured_media":0,"template":"","products_tags":[44],"resource_type":[90],"application_areas":[50],"therapeutic_areas":[54],"target_categories":[61],"target_families":[332,333,340],"targets":[91,92,93],"resource_keyword":[],"class_list":["post-6741","resource_library","type-resource_library","status-publish","hentry","products_tags-patchliner","resource_type-application-note","application_areas-ion-channels","therapeutic_areas-cardiac-safety-cipa","target_categories-voltage-gated-ion-channels","target_families-nav-channels","target_families-kv-channels","target_families-cav-channels","targets-cav1-2","targets-kv11-1-herg","targets-nav1-5"],"acf":[],"_links":{"self":[{"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/resource_library\/6741","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/resource_library"}],"about":[{"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/types\/resource_library"}],"wp:attachment":[{"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/media?parent=6741"}],"wp:term":[{"taxonomy":"products_tags","embeddable":true,"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/products_tags?post=6741"},{"taxonomy":"resource_type","embeddable":true,"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/resource_type?post=6741"},{"taxonomy":"application_areas","embeddable":true,"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/application_areas?post=6741"},{"taxonomy":"therapeutic_areas","embeddable":true,"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/therapeutic_areas?post=6741"},{"taxonomy":"target_categories","embeddable":true,"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/target_categories?post=6741"},{"taxonomy":"target_families","embeddable":true,"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/target_families?post=6741"},{"taxonomy":"targets","embeddable":true,"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/targets?post=6741"},{"taxonomy":"resource_keyword","embeddable":true,"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/resource_keyword?post=6741"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
