DAO Peptide

DAO peptide is supplied as 100 μ g of dried peptide. When the peptide is reconstituted in 200 μ L water, the concentration will be 0.5 mg/mL.

DAO Peptide is used for blocking the activity of DAO antibody (catalog number 42-867) . The DAO antibody ships at 0.5 mg/mL and the DAO Peptide ships as a 100 μ g pellet. When peptide is reconstituted in 200 μ L water, the concentration will be 0.5 mg/mL, identical to that of the antibody. The best starting ratio would be 1:1 (which means molar excess of peptide relative to antibody when identical volumes are mixed) . Mix equal volume of peptide and antibody at the required dilution and leave at ambient temperature for 20 minutes. Then incubate and develop in parallel two blots: one with the antibody and one with the antibody which has been pre-absorbed with the provided peptide.
