Polyclonal antibodies (pAbs) against PSA and P-TSMP were obtained
fromPi Bioscientific Inc. In brief, the pAbswere raised in goats following
standard immunization protocols, purified fromserumon Protein G columns
and then additionally purified on affinity columns using an ÄKTA
prime FPLC unit (GE Healthcare Life Sciences, Pittsburgh, PA). Ensuing
IgG antibodies were assessed for purity and functionality by denaturing
polyacrylamide gel electrophoresis and indirect ELISA using 10 μg/ml
PSA or P-TSMP bound to polystyrene 96-well plates using horseradish
peroxidase conjugated rabbit-anti-goat IgG (KPL, Gaithersberg, MD) as
a detection reagent. Note that anti-PSA antibodieswere used to prepare
the raw pork LFD and the anti-P-TSMP antibodieswere used to generate
the cooked pork LFD
