DNAzol ® , non-toxic DNA isolation reagent. Genomic DNA isolation reagent for use with tissue, cells and liquids. NON-TOXIC. Requires no phenol. Fast, reliable and simple. 1 ml of DNAzol isolates DNA from 25-50 mg tissue or 1-3 x 107 cells. DNAzol ® , is a registered Trademark of Molecular Research Inc.

DNAzol ® BD (isolation from blood) Is a reagent specifically formulated for the isolation of genomic DNA from whole blood. The DNAzol ® BD patented procedure (U. S. patent 5,945,515) is based on the use of a novel guanidine - detergent lysing solution which hydrolyzes RNA and allows the selective precipitation of DNA from the lysate. The isolation of genomic DNA from blood using DNAzol ® BD is fast, efficient and economical . In addition to the isolation of genomic DNA, DNAzol ® BD can also be u

DNAzol ® ES, Extra Strength Is an extra strength DNAzol ® reagent specifically formulated for the isolation of genomic DNA from plants. The patented procedure (U.S. patent no. 5,945,515) is based on the use of a novel guanidine-detergent lysing solution that allows the selective precipitation of DNA from the lysate [1]. The DNAzol ® ES protocol is fast and permits efficient isolation of genomic DNA from a variety of plant tissues [2, 3]. In the DNAzol ® ES procedure, plant samples are pulverized

DNAzol ® Direct Is a universal reagent for processing biological samples for direct PCR. No isolation of DNA is required. The DNAzol ® Direct procedure is simple. Lyse a sample in DNAzol ® Direct for 15 minutes, add an aliquot of the resulting lysate to a PCR mix, and perform amplification of a selected DNA fragment(s). The standard DNAzol ® Direct procedure supports PCR amplification of DNA fragments up to 8 kb long. DNAzol ® Direct (U.S. patent 7,727,718) composition and procedure are based on
