Filter mating assay

WebA variation of the filter-mating assay can be carried out using liquid cultures. In this method, the mixed cell suspension of donor and recipient cells is added to a sterile universal and incubated at 37°C from 30 min to 16 h (see Note 3). After incubation, the conjugated cell mix should be vortexed vigorously to disrupt the mating pairs. WebDec 22, 2014 · Mating was carried out on microfiber filters (GF/C Whatman filter, 24 mm).
