The Method of Loci has been used since ancient times to memorize important information.
The NE-PER Nuclear and Cytoplasmic Extraction Reagent Kit is a reagent-based protocol that enables the stepwise lysis of cells, separation of the cytoplasm from the intact nuclei and then extraction of nuclear proteins away from genomic DNA and mRNA.
DNA extraction. DNA extraction is the process by which a cell is broken open to expose and extract its DNA. This is done by breaking down and emulsifying the fat and proteins that make up the cell's membrane through the addition of both salt and detergent solutions. Then the DNA is separated by by adding alcohol and centrifuging the resulting solution.
