Human ERG channel has been stably expressed in HEK293 cell line and its expression was confirmed by Western blotting. The channel activity of hERG was characterized by a fluorescence-based assay using thallium influx as a surrogate indicator of potassium ion channel activity coupled with a thallium-sensitive fluorescent dye. When hERG-HEK293 cells were pre-loaded with thallium-sensitive dye and stimulated with stimulus buffer containing potassium/thallium, thallium ions flowed through the open hERG channels into the cells and bound the dye, generating a fluorescent signal. The hERG channel activity in hERG-HEK293 cells was blocked by hERG channel blockers, cisapride or dofetilide, causing the fluorescent signal triggered by thallium influx to drop to the basal level.

The firefly luciferase gene is controlled by a human Foxp3 promoter and an enhancer-like conserved noncoding sequence upstream of the Foxp3 promoter.

The PD-1/PD-L1 Inhibitor Screening Cell-Based Assay is a bioluminescent cell-based assay that can be used to screen and profile inhibitors of PD-1:PD-L1 or PD-1:PD-L2 interaction. The assay consists of two main components: • PD-1 Effector cells (PD-1/NFAT reporter-Jurkat cells): Reporter Jurkat T cells expressing firefly luciferase gene under the control of NFAT response elements and also constitutively expressing human PD-1. These cryopreserved cells are provided in a thaw-and-use format that does not require cell propagation. • Expression vectors for TCR activator, human PD-L1, and human PD-L2: Transfection-ready vectors are used to transfect cells to create the target cells that overexpress PD-L1 or PD-L2 and an engineered cell surface T cell receptor (TCR) activator.

This cell line has been engineered for use with the CRISPR Synergistic Activation Mediator (SAM) system to induce transcriptional activation and expression of any gene of interest. Cells stably express a mutated dCas9 (Streptococcus pyogenes CRISPR associated protein 9), lacking any endonuclease activity, fused to VP64, a transcriptional activator. Stable dCas9-VP64 expression is maintained with Blasticidin resistance. Cells also stably express P65 (Transcription Factor p65, or Nuclear Factor NF-κB p65) and HSF1 (Heat Shock Factor 1) fused with an MS2 tag, which is maintained with Hygromycin resistance. When these cells are transfected with an MS2-tagged sgRNA targeting the promoter region of the gene of interest, dCas9-VP64 and MS2-P65-HSF1 are recruited to the site in the genomic DNA and begin transcription, inducing expression of the desired gene.

Cas9 (Streptococcus pyogenes CRISPR associated protein 9) is an endonuclease enzyme that, when recruited to a specific DNA sequence by the sgRNA (single guide RNA), introduces a double stranded break into the DNA. This double stranded break is repaired in mammalian cells either through Non-Homologous End Joining or Homologous Recombination. Non-Homologous End Joining often results in the deletion or insertion of several base pairs at the cut site, which, when resulting in a frameshift, causes the functional inactivation of the targeted gene. Cas9-expressing Neuro2A cell pool can be transduced or electroporated with sgRNA targeting a gene of interest to quickly generate knock-out cell pools or cell lines.
