I’m using Longmires buffer to store skin swabs. I’m ready for extraction using Qiagens DNeasy kit but wonder if I should use only the swab in the lysis step? I wouldn’t like to discard the buffer if it has DNA in it from storage. Will centrifuging the storage buffer work to isolate any floating DNA? Or how might I amend the Quagen protocol in order to process the swab and 500 uL of storage buffer?
