DNA extraction from algae remains difficult due to the presence of a rigid cell wall that contains sulphated polysaccharides. Viscous soluble polysaccharides are released by grinding Algae material in liquid nitrogen that are difficult to separate from DNA, therefore CTAB method has been applied for DNA extraction. The scale of extraction is dependent on the amount of starting material.
HiPurA® Marine Algae DNA Purification Kit an easy method for isolation of DNA from marine algae using CTAB. CTAB is used to break open and solubilize the contents of plant cells. The concentration of DNA can be estimated by agarose gel electrophoresis.
