Beckman has two types of SPRi beads- AMPure and SPRIselect, the later are much more expensive. According to their data sheets Ampure XP is used for PCR product purification while SPRIselect is used for size selection. However I know that many people use AMPure XP for double sided size selection. Does somebody knows what is the difference between AMPure XP and SPRIselect?
Is it the beads coating (similar to difference between AMPure and AMPure XP) or may be the buffer components (PEG? NaCl, other crowding agent)?
Does anybody know for sure what are the bufferes composed of?
Thanks
