Total cellular DNA purified using Company Q’s DNeasy Plant Kit and Omega Bio-tek’s E.Z.N.A.® HP Plant DNA Kit. Purified total cellular DNA from various plant sources was isolated with the DNeasy Plant Kit and E.Z.N.A.® HP Plant DNA Kit. DNA was extracted from 100 mg fresh leaves from the following plants: lanes 2-5 from maize, lanes 6-9 from peanut, lanes 10-13 from tomato and lanes 14-17 from soybean. Total cellular DNA (10% of total purified DNA) was analyzed on a 0.8% agarose gel to demonstrate yeild and quality of the DNA. M: Lambda Hind III marker.
