Details

MicroSpin S-400 HR spin columns for DNA purification from unincorporated primers (<32-mers) and nucleotides using spin-column chromatography in applications including desalting, buffer exchange, and primer removal.

Accommodates 25 to 50 μL for post-PCR clean-up prior to cloning or a second amplification reaction, or 25 to 100 μL for all other applications
Convenient: prepacked with Sephacryl™ S-400 HR pre-equilibrated in TE (Tris/EDTA) buffer
Ready to use: requires less than 4 min from sample application to collection of purified product
Tested in nickase, single- and double-stranded exonuclease, and RNase assays

MicroSpin S-400 HR spin columns rely on gel filtration for PCR clean-up. Good product yield and purity are obtained with sample volumes from 25-100 μL , and from nanogram to milligram quantities of DNA.

MicroSpinÂ S-200,Â S-300Â and S-400 HR spin columns contain Sephacryl resin of differing pore sizes. They allow DNA purification by the process of gel filtration. Molecules larger than the largest pores in the Sephacryl are excluded from the gel and elute first. Intermediate size molecules penetrate the matrix to varying extents, depending on their size and the resin used. Penetration of the matrix retards progress through the spin column; very small molecules elute last. The volume required to elute these small molecules is dependent on the volume available both inside and outside the pores i.e. the bed volume.
