Supplement T, a preparation for cell culture growth, is just as effective as commercially available tryptose. It has met high demands throughout its application over six years under conditions of large-scale production of permanent cell lines. Supplement B has been used with good success in commercial production for breeding of FMD virus in BHC cells of IBR/IPN and PI-3 viruses in calf kidney cells cultures and of embryonic duck fibroblast cell cultures for production of vaccines against Marek's disease.
