One vial contains 10 mg of ALFA elution peptide to prepare a native elution buffer for the ALFA Selector PE. We recommend to dissolve the lyophilized peptide in 250 µL pure water to get a 100x stock solution. This peptide will not efficiently elute ALFA-tagged proteins from the ALFA Selector ST (super tight). For reconstitution instructions please refer to the Datasheet.
PLEASE NOTE: Every unit of ALFA Selector PE comes with a 1 mg lyophilized peptide (sufficient for 2.5 mL elution buffer). If you need more elution buffer, this is the right product for you.
