Table 1. Performance of MagCore® Genomic DNA extraction on human whole blood samples treated with various anticoagulants. The performance of DNA extraction from human whole blood samples containing EDTA, sodium citrate, sodium fluoride and lithium heparin from different types of blood collection tubes. Concentration and purity of isolated genomic DNA are measured by Nanodrop n-1000.

Figure 2. Analysis of DNA product integrity on gene Cbl-b (1.7kb) from various human whole blood samples. Effect of anticoagulants on the integrity of DNA isolated from MagCore® instruments was investigated on agarose gel electrophoresis.

Figure 3. Linear relationship between DNA yield and different sample dilutions. Human whole blood samples of 20, 50, 80, 100, 150, and 200μl from a single donor were diluted to 200μl using PBS buffer. The amount of DNA was calculated using A260 results. No significant difference was observed in the DNA yield from eluates of 100μl and 200μl.

Figure 4. Consistency in yield and purity isolated from human whole blood of different sample volumes. The quality of human whole blood DNA from 16 individuals was studied using Nanodrop n-1000. Yield and purity of DNA isolated from MagCore® instruments were calculated from A260 and A260 /A280. The average amount of DNA yielded from 400µl samples was similar to two times the amount of DNA from 200µl samples along with similar purity.
