In immunoelectrophoresis against mouse milk precipitation of not less than 7 different proteins may be obtained. However the number of visible precipitin lines varies widely among individual specimens of mouse milk. The total concentration of protein, their proportion of the different protein components change markedly during the course of lactation. There are also strain differences in the protein composition, but differences among individual animals tend to be greater. A protein detected in a mouse secretion by RAM/TM may be of secretory origin, or it may be a plasma protein presumably entering in the secretion from the surrounding capillary vessels and through interstitial tissues. Virtually every plasma protein may also be present at a detectable level in milk. Not all precipitable proteins have been identified. Known proteins include secretory IgA and other immunoglobulins, free secretory component, lactoferrin, components of the complement system and albumin In immunoelectrophoresis to identify the protein pattern in an individual milk sample, to compare individual patterns and to make comparisons with serum protein patterns or those of other secretions. to identify individual components, and significant changes in concentration. To test the purity of an isolated milk protein.
