Removing of the agarosé on the back again of the photo slides. iv. Le t the slides dried out and after that s tore at r oom heat until make use of. m. At least 2 h before the experiments: get ready 0.7 so lution of LMP agarose in PBS and place it at 37 Chemical in a watér-bath until make use of. 2. Prepare cells The amount of harvested tissues can end up being adjusted regarding to the size of the cells.Learn even more DOI: 10.21769BioProtoc.915 Cite this publication Elisa Boutet-Robinet 30.75 John Sabatier University or college - Toulouse III Didiér Trouche Yvan Canitrót 35.72 John Sabatier University or college - Toulouse III Abstract The Comet assay (or Solitary Cell Skin gels Electrophoresis assay) is certainly a delicate technique to detect DNA harm at the level of an personal cell.This technique is structured on micro-electrophoresis of tissues DNA content material.
![]() Broken DNA (billed DNA) migrates in this field, developing the end of a comét, while undamagéd DNA stayed in the mind of the comet. The pursuing document describes the process to understand a neutral comet assay. This assay can end up being used to various cell types and has been useful for several programs in areas of toxicology or DNA harm and restoration.

Finish of the slides with agarose Slides covering with agarose. In this situation eight photo slides are subjected to electrophoresis, four by row.

This method is based on micro- electrophoresis of tissues DNA conten capital t. Briefly, cells are usually em bédded in agarose, Iysed and subm ittéd to an electric powered industry, before the staining stage with a fIuorescent DN A binding dye. Dam old DNA (charged DNA) migratés in this fieI d, f órming the tail of a comet, while undamaged DNA remained in the head of the comet. Capital t he following docum ent dés cribes the protocol to recognize a natural comet assay. This assay can be appli ed to different cell varieties and offers been useful for several ap plications in areas of toxicology ór DN A harm and maintenance. Tissue to evaluate 2.

Komet 6.0 software (Andor Technologies) Treatment 1. Prepare agarose option and glides. At least 24 l before the experiments: we. Prepare 0.8 option of Seakem Agarosé in PB T. Pre-coat Top Frost glides by sinking in a vertic al jar containing dissolved agarose, stirred with a permanent magnetic stirrer and e ept at 100 D (Figure 1). Number 1. Layer of the photo slides with agarose iii. Remove off the agarose in excess by wiping the back again of the film negatives (Body 2). Getting rid of of the agarosé on the back of the photo slides. Le t the glides dry and after that s took at r oom temperature until make use of. At minimum 2 l before the trials: prepare 0.7 so lution of LMP agarose in PBS and location it at 37 G in a watér-bath until use. Prepare cells The number of harvested tissue can be adjusted regarding to the dimension of the tissue.
