Bio-Shield Goat Colostrum
Catalog number : B1348 /B1396
Bio-Shield Goat Colostrum is an ELISA test that detects the adulteration of milk with goat’s IgG.
Early-lactation milk contains colostrum which provides immune protection and nurture the newborn.
Colostrum has 50−100 times higher levels of whey proteins (β-lactoglobulin, α-lactalbumin, immuno-globulins, lactoperoxidase (LPO), lactoferrin, proteinase inhibitors, albumin, α2-macroglobulin, and transferrin), vitamins, and minerals, and lower levels of lactose and casein than milk. These higher whey proteins/casein ratios, may affect the organoleptic properties of dairy products and result in tech-nological problems during their production (e.g. precipitation on the surface of equipment during heat treatments).
The manufacturing efficiency of cheese production is lower, because of the low casein levels and the high concentration of lactoferrin and LPO, and the nonspecific antimicrobial properties that alter the growth of bacteria playing a crucial role in fermentation and cheese maturation. Thus, adulteration of milk with raw colostrum is an illegitimate practice for the dairy industry.
A milk sample containing more than 1-2 mg/mL caprine IgG, is considered to be adulterated with colostrum. This Elisa kit can be used to detect and quantify the presence of colostrum in milk.
