One vial contains 10 mg of ALFA elution peptide to prepare a native elution buffer for the ALFA Selector PE. We recommend dissolving 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).

PLEASE NOTE: Every unit of ALFA Selector PE is delivered including a vial containing 10 mg lyophilized peptide (sufficient for 25 mL elution buffer). This is the right product for you if you need more elution peptides for your experiments.

Formulation: Lyophilized powder containing 10 mg ALFA elution peptide. Reconstitute with 250 µL sterile water to obtain a 100x stock solution (20 mM).
kDa: -
Ext Coef: -
Shipping: Ambient temperature
Storing: Vials containing lyophilized peptide can be stored at 4 °C for up to 6 months. When reconstituted in water, aliquot and store at -20°C or below.

Please dissolve the lyophilized peptide (10 mg) in 250 µl of distilled water. This results in an ALFA peptide concentration of 40 mg/ml equivalent to 20 mM (100x).
