Notes:
Triose phosphate isomerase (TPI) was purified from bovine semimembranosus muscle using acetone precipitation, ammonium sulfate precipitation and cation exchange chormatography. Anti-TPI polyclonal antibodies (PAbs) were raised in rabbits. A sandwich ELISA with a limit of detection of 1 μg TPI/mL was developed using PAbs for capture and biotinylated PAbs for detection. Cross-reactivities of antibodies with other protein in beef muscle extracts and with TPI from different animal species were examined. TPI concentration and activity of ground beef decreased (P 〈 0.0001) as cooking temperature was increased from 48.9 to 76.7°C, suggesting that these assays might be used to monitor processing adequacy of beef products.
