Novel method for detecting bovine immunoglobulin G in dried porcine plasma as an indicator of bovine plasma contamination.
Current U.S. Food and Drug Administration regulations prohibit feeding of protein derived from mammalian tissue, excluding blood and blood products and any product that consists entirely of porcine or equine protein. A novel lateral flow immunoassay device has been developed that can quickly and qualitatively determine the presence of bovine immunoglobulin G (IgG), a major component in blood products, at very low levels (0.01% v/v). The device can be used to test for bovine IgG commingling in spray-dried porcine plasma used in the feed industry. Producers and consumers alike could use this device to verify product content at threshold levels.
