Fecal Pellets and Microflora Donors

Fecal Pellets and Microflora Donors

Altered Schaedler Flora (ASF)

Taconic Biosciences maintains gnotobiotic animals which are colonized exclusively with the Altered Schaedler Flora (ASF). These animals are ideal microflora donors for germ-free mice you want to associate with a defined flora. For customers wishing to obtain ASF for association purposes, Taconic strongly recommends purchase of live animal donors rather than purchase of fecal pellets. The ASF contains obligate anaerobic bacteria which have limited viability in passed feces. Note that ASF360 is present in extremely low levels in colonized mice and may not be detected in feces. Please see Taconic's recommended association protocol. ASF fecal pellets are available for experimental purposes, but are not recommended for microflora association.

Fecal Pellets

Taconic can provide fecal pellets from mice at a variety of health standards, from Germ Free to Murine Pathogen Free™. These may be used for molecular biology/PCR studies. For the items below, Taconic provides one vial containing 10 freshly collected fecal pellets. We recommend shipping fecal pellets overnight at room temperature. For prolonged transit, we recommend shipping frozen on dry ice. Taconic does not recommend use of these fecal pellets for microflora association or to culture particular microflora members.
