Soybean trypsin inhibitor and beta-amylase stimulate macrophages.
Mature soybean seeds were found to contain macrophage stimulation activity. The activity existed in a water-soluble fraction of soybean whey. Gel filtration, DEAE-cellulose column chromatography and high-performance liquid chromatography of the water-soluble fraction gave two active proteins. By N-terminal and total amino acid analyses, these were effectively stimulated by each of the two proteins to produce nitrite.
