The DharmaconTM All-in-one systemThe All-in-one system offers the simplest CRISPR workflow available – a single reagent, easy delivery and straightforward selection. Single reagentUsing a single vector to express both CRISPR nuclease and gene-specific guide RNA eliminates the need to perform sequential transduction and selection steps. Easy deliveryLentiviral packaging allows for easy transduction into nearly any cell type. Eliminating the need for toxic transfection reagents or electroporation techniques makes the All-in-one system particularly useful for genome editing and transcriptional modulation in difficult-to-transfect or primary cell types. Transduction-ready reagents also eliminate any cloning or in vitro transcription steps. Straightforward selectionThe choice of a puromycin resistance gene or EGFP marker allows for straightforward selection of cells that have successfully integrated the vector. EGFP is recommended for rapid enrichment of targeted cells, as FACS analysis may be performed as soon as fluorescence is expressed.

All-in-one CRISPR gene knockout, activation, and interference workflow

The power of the All-in-one system lies in the simplicity of it's workflow
To transduce, simply thaw the reagent and add the appropriate amount to your cells. Then easily select for targeted cells using puromycin or enrich using FACS.
When using puromycin selection, growth medium is replaced with puromycin selection medium 24-48 hours post-transduction. Cells are then monitored daily until growing normally in the selection medium. Once growth is stable, isolation and/or expansion of the targeted cell population(s) may occur.
Alternatively, using the EGFP fluorescent reporter option offers the ability to enrich for edited cells via FACS selection in as few as 72 hours post-transduction. The FACS enrichment workflow is especially useful for short-lived cell types, such as primary cells.
For CRISPRa and CRISPRi, we recommend the mixed cell population workflow.
Efficient transcriptional activation with CRISPRmod CRISPRa All-in-one Puro-dCas9-VPR![]() HEK293T or HCT-116 cells were plated in 96-well plates at 20,000 or 5,000 cells/well, respectively, and transduced with 0.3 MOI CRISPRa all-in-one virus containing sgRNAs targeting POU5F1, TTN, IL1R2, or Non-targeting control #2 (NTC2). Cells were selected with 2.5 µg/µL puromycin for 5 days, allowed to expand, and harvested two weeks post-transduction. Relative gene expression was calculated using RT-qPCR. The relative expression of each gene was calculated with the ∆∆Cq method using ACTB as the housekeeping gene and normalized to a non-targeting control.
