The βDDM extractable fraction increases with time until it reaches saturation around 6 hr (A). When the non-aqueous fraction is first treated with urea and then βDDM (B), the protein first fractionates in the detergent fraction, implying that protein does integrate in the membranes that is extractable by βDDM. Vpu is indicated by a black arrow.
