Hi there,

All the minicolumns from these kits are strictly the same, the difference lies in the reagents.

Thanks dear Liger!

Didn't know that separate kits are available for gel purification and PCR cleanup. The kit that we use serve both the purpose, have a common column and common reagents.

Hi there!

I agree with Dominique. These are generally silica based columns that they provide in PCR clean up kit or gel extraction kit. Only difference is the binding buffer in gel extraction contains agarase and chaotropic agents whereas in the PCR clean up these ain't  required. I think you can safely use them.

Hope it helps! 

As you mentioned you have a single band and you can simply do double ethanol precipitations for purification. Alternatively you can prepare a preparaetive gel and excise your band from your gel and use the gel purification kit to recover your PCR product.

From my experience gel purification has lower yields and is more time consuming!

Yes you can
