Comparison of gDNA Isolated from Whole Blood with Auto-Mag® Silica Coated Magnetic Beads (D-1)

Figure 1. Genomic DNA (gDNA) was isolated from 50, 100, and 200 µL of whole blood using the Auto-Mag® Blood & Tissue DNA Isolation Kit formulated with Auto-Mag® Silica-Coated Magnetic Beads (D-1) and a competitor’s M kit. Following isolation, 10 µL of each 100 µL DNA eluate was analyzed on a 1.2% agarose gel. The results demonstrate consistent DNA isolation across the tested sample volumes, with Auto-Mag® Silica-Coated Magnetic Beads (D-1) showing higher DNA recovery than the competitor’s product.
