    A quantitative ELISA was developed for bovine milk ferritin with an assay limit of 0.16 ng/mL of bovine spleen ferritin. Ferritin-binding activity was detected in bovine milk samples, and this binding activity was inhibited by increasing ionic strength with the addition of 0.5 M (NH4)2SO4. Heat treatment (60 degrees C, 20 min) of bovine milk in the presence of 0.5 M (NH4)2SO4 resulted in a 15 to 58% increase in ferritin concentrations compared with untreated samples. Although the recovery of bovine spleen ferritin added to milk was still low (55 to 90%), even in the presence of increased ionic strength with 0.5 M (NH4)2SO4, recovery was improved by heat treatment at 60 degrees C for 20 min (92 to 95%). Milk ferritin concentrations in 30 milk samples from quarters of 25 cows with mastitis (mean +/- SE: 134.2 +/- 28.7 ng/mL) were significantly higher than those in 17 quarter milk samples from 17 noninfected lactating cows (7.2 +/- 1.2 ng/mL), suggesting that bovine milk contains putative ferritin-binding proteins that inhibit immunoassay for milk ferritin and that bovine milk ferritin is an indicator of IMI.
