Agar and agarose gel agar is a mixture of poly saccharides extracted from sea weeds. The average time consumed by the pcr reaction along with the agarose gel electrophoresis and data interpretation is approximately 4 to 4 5 hours. Agarose is a highly purified uncharged polysaccharide derived from agar.

Ethidium bromide or homidium bromide chloride salt homidium chloride is an intercalating agent commonly used as a fluorescent tag nucleic acid stain in molecular biology laboratories for techniques such as agarose gel electrophoresis it is commonly abbreviated as etbr which is also an abbreviation for bromoethane to avoid confusion some laboratories have used the abbreviation ethbr for.
