an indirect fluorescent antibody test 6,8 or an S neurona agglutination test. 5 Western blot analysis for S neurona –specific IgG in CSF is still the most widely used ancillary test for EPM in horses. The principle underlying the use of western

valuable proteins, including IgG. Equine plasma collection facilities strive to harvest high-volume, high-quality plasma as frequently as possible without causing sustained protein depletion in donor horses. The purpose of the study reported here was to

Lambs are born with negligible serum IgG concentrations, so neonatal lambs depend on the passive transfer of maternal IgG in colostrum to provide humoral immunity during the neonatal period. 1–6 Failure of the neonatal lambs to obtain and absorb

gel immunodiffusion (often referred to as AGID or ID) is traditionally used for the demonstration of anti-coccidioidal IgM and IgG antibodies and can be performed quantitatively to measure an antibody titer. Chitinase 1 (CTS1) is the seroreactive
