General description

OCT4 is the key transcription factor (TF) that maintains pluripotency of embryonic stem cells and plays a critical role in reinstating cellular pluripotency. The expression of OCT4 is stringently silenced in differentiated cells. Activation of silenced OCT4 gene has become a hallmark event during epigenetic reprogramming into iPSCs. The positive control OCT4 gRNA design has been tested with the dCas9-p300 plasmid in HEK293 cells and shown to increase OCT4 mRNA transcript levels over three-fold compared to a negative control.


Functional Genomics/Target Validation
• Epigenetic Modification
• Transcriptional Activation

Features and Benefits

Serves as an experimental control for the CRISPR dCas9-p300 activation system. A positive experiment will result in an increased level of mRNA via qPCR or TaqMan PCR assay.


1 vial containing 1ug of U6-gRNA plasmid expressing a guide sequence to human OCT4 (Octamer-binding transcription factor-4 or POU5F1).
