  • BP001020-Z65: Recombinant Human transcription factor p65 protein

    Source: Baculovirus, SF9 insect cells-derived.
    Bioactivity test: 1 unit equals 1 nanogram of purified protein. 10 unit is sufficient for a gel mobility shift assay in a 20 ul reaction; 50 units are sufficient for reconstituted transcription assay and 100 units are sufficient for a protein-protein interaction assay.
    Purity: > 90%, by SDS-PAGE.
    Endotoxin Level: < 1.0 EU per 1 ug of the protein by the LAL method.
