Sequence analysis of porcine polymeric immunoglobulin receptor from mammary epithelial cells present in colostrum

摘要

The composition o colostrum is quite different from that of mature milk. In particular, colostrum contains relatively high concentrations of proteins responsible for the immunological defence of newborns,such as lactoferrin, lactoperoxidase, lysozyme and immunolglobulins(Farkye, 1992; Cals et al. 1994; Telemo & Hanson, 1996; Wang et al. 1997).
