E.Z.N.A.® Insect DNA kit

Supplier: OMEGA BIOTEK

The E.Z.N.A.® Insect DNA kit is designed for efficient recovery of genomic DNA up to 60 kb in size from insects, arthropods, roundworms, flatworms, invertebrates, as well as some plant tissue samples. The method is suitable for samples frozen or preserved in alcohol or DNE solution, and good results can be obtained with formalin preserved material. The procedure relies on the well established properties of the cationic detergent, cetyltrimethyl ammonium bromide (CTAB), in conjunction with the selective DNA binding of HiBind matrix. This allows salts, proteins and other contaminants to be removed to yield high quality genomic DNA suitable for downstream applications such as endonuclease digestion, thermal cycle amplification, and hybridisation techniques.
