Homogeneous system eliminates post-hybridization wash steps, minimizing leakage and signal degradation
Routine use of external controls enables consistent assay performance
Compatible with high throughput testing platforms
Low input volume saves precious samples for additional analyses
The FLOWSCRIPT® HPV E6/E7 assay kit is a flow cytometry based assay for the detection of E6/E7 mRNA in whole cells. The assay employs a novel in situ hybridization technique utilizing cocktails of oligonucleotide probes specific to multiple targets within the E6 and E7 genes to ensure the detection of these transcripts from most known variants of high risk HPV. Fixed and permeabilized cells are hybridized with probes and analyzed by flow cytometry for E6/E7 transcript expression. Each probe contains a fluorescent label and a quenching molecule whereby no signal is observed in the absence of target. During hybridization, the probe anneals to the target sequence, thereby emitting a detectable signal.
Typical expected results. Negative control cells (ENZ-GEN302) and Positive control cells (ENZ-GEN301) were assayed using the FLOWSCRIPT™ E6/E7 HPV Assay. Negative control cells (left panel) that over-express oncoprotein E6/E6 mRNA comprise < 5% of cells in the analysis gate. Positive control cells that over-express oncoprotein E6/E7 mRNA comprise > 95% of cells in the analysis gate.
FLOWSCRIPT™ HPV E6/E7 Assay Workflow
The human HPV genome contains 8 open reading frames which include E6, E7, E1, E2, E4, E5, L2 and L1. \E\" or \"L\" refer to \"early\" or \"late\" functions, respectively. During the course of cancer development, the viral molecule frequently becomes integrated into host-cell DNA."
