METHODS FOR DETERMINING THE LEVELS OF TGF- IN A COMPOSITION

摘要

A novel method for determining the levels of TGF-1 or TGF-2 in a sample of milk, raw protein source, or nutritional composition is provided. The method involves, in some cases, reconstituting the sample; in some cases, centrifuging the sample; activating the sample using particular ratios of sample:acid:base; diluting the sample using particular ratios of sample:buffer agent; and determining the concentration of TGF-1 in the sample using an ELISA assay.
