Purity of PanNuclease. From lane 1-4: 4.0, 2.0, 1.0, 0.5 μg of PanNuclease were separated by SDS-PAGE under reducing condition and stained with Coomassie Blue. | |
The activity of PanNuclease/Supplier A was examined by incubation of 37μg of salmon and calf thymus DNA mixture with 02, 10.5, 2, 1, 0.5 units (ane 1-7)at 37°C for 30 minutes, separated with 1.5% agarose. Lane2-4: PanNuclease , Lane 5-7: Supplier A. | |
Degradation of DNA(A), DNA+RNA(B)contaminants in cell paste (CP)and conditioned media(CM)generated from a bio-reactor. 2L of culture of CHO cell was harvested at day 10 and total cell number reached 2x109.Amount of PanNuclease were added: lane 1&4: 0U, lane 2 & 5: 1U, Lane 3&6: 0.1U to treat 2x107 cells(CP) in 50μl of the buffer(20mM Tris-HCl ,pH8.0, 1M Urea, 1% Triton X-100)or 500ml of conditioned media (CM)and incubated at room temperature for 25 min. DNA and RNA were extracted, then separated. |
