DNA Recovery as a Function of Device MWCO


Nanosep Centrifugal Device: DNA Recovery as a Function of Device MWCO
 
A 500 μL sample of a 100 μg/mL DNA fragment solution containing 50 and 500 bp double-stranded DNA fragments was centrifuged at 5,000 x g in Nanosep devices to a final volume of 50 μL. Recovered samples were quantitated using absorbance at 260 nm. The 100K device was able to differentiate between the sizes of the DNA fragments.

Omega™ Membrane Has the Lowest Non-Specific DNA Binding


Omega™ Membrane Has the Lowest Non-Specific DNA Binding

A 500 μL sample of a 32P-labeled PCR product (400 bp, 50 ng/mL) was centrifuged at 5,000 x g in a 100K Nanosep or competitive device. The retained DNA was recovered in 40 μL TE (10 mM Tris, 1 mM EDTA, pH 8). The remaining radioactivity in the device was counted in a scintillation counter. A value at 1000 CPM roughly corresponds to 1% of the total radioactive sample. Omega membrane has the lowest non-specific binding, resulting in highest DNA recoveries. In general, DNA molecular weights do not correspond well with the MWCO because DNA is a long linear molecule. Effective retention of DNA by an ultrafiltration membrane requires a reduction in g-force to 5,000 x g. Otherwise, DNA can be forced through many MWCO membranes regardless of size.
