Comet assay images
WebComet assay, or single cell gel electrophoresis assay, is a powerful technique for quantitating DNA damage and repair in eukaryotic cells and some prokaryotic cells. This technique uses cells that are embedded into … Webto quantify the DNA damage using the comet assay, the images were analyzed by 2 methods. Comets were scored using stan-dard stages and using the CometScore, which considered TL and OTM. Although both methods are frequently used for the quantification of comet assays,24-26 the distinction between them and their applicability is not clear.

The concept underlying the SCGE assay is that undamaged DNA retains a highly organized association with matrix proteins in the nucleus. When damaged, this organization is disrupted. The individual strands of DNA lose their compact structure and relax, expanding out of the cavity into the agarose. When the electric field is applied the DNA, which has an overall negative charge, is drawn towards the positively charged anode. Undamaged DNA strands are too large and do … WebThe comet images generated by both assays were entirely comparable to each other in terms of the overall comet shape and regularity. Figure 2.
