Description: Peptide to Flag Peptide Form: Lyophilized powder CAS Number : 98849-88-8Molecular Formula : C41H60N10O20Molecular Weight : 1012.99Purity : > 95%Chemical Structure : H-Asp-Tyr-Lys-Asp-Asp-Asp-Asp-Lys-OHApplication : The FLAG Epitope Peptide consists of eight amino acids (DYKDDDDK) and represents a versatile fusion tag for the purification of recombinant proteins. It can be enzymatically removed with enterokinase which cleaves C-terminally to the tag sequence. The peptide is commonly used for the elution of immunoaffinity chromatography-purified recombinant proteins.Storage/Stability : Shipped at 4°C. Store at -20°C for one year.
