DxNow CSI-Q -Chip-Based Sperm Identification and Quantitation
The DxNow CSI-Q™ cartridge is designed to aid the forensic DNA analyst to rapidly identify the most probative sample(s) in forensic DNA casework to submit for further DNA Analysis. CSI-Q is based on the same scientific principles of the innovative NGDE™ technology. Sexual assault evidence samples will be extracted by standard laboratory procedure and an aliquot will be loaded on the chip and washed. If sperm are present in the extract, they will be captured by the oligonucleotide present in the channel and all other cell types will be washed from the chip.
Upon inspection of the chip under a microscope, those samples in which sperm are detected will then be submitted to the testing laboratory for subsequent analysis. The CSI-Q disposable cartridges represent a confirmatory test for the presence of sperm, helping the laboratory to process the most relevant samples, increasing the efficiency and effectiveness of the forensic DNA process.
