Inhibition Enzyme-Linked Immunosorbent Assay for Detection of Pseudomonas fluorescens Proteases in Ultrahigh-Temperature-Treated Milk.
An inhibition enzyme-linked immunosorbent assay was developed to detect low levels of the proteases extracted from four strains of Pseudomonas fluorescens. The assay detected between 0.24 and 7.8 ng of protease per ml of ultrahigh-temperature-treated milk and could be completed within 6 h. It could be used as a framework for a test system for quantifying spoilage proteases in dairy products.
