Used for the quantitative detection of human alpha-lactalbumin in biological samples such as milk, serum, or cell culture supernatants. This ELISA kit is widely applied in clinical research to study infant nutrition, breast milk composition, and lactation biology. It supports investigations into immune responses related to milk proteins and is useful in diagnosing or monitoring milk allergies and intolerances. The assay enables high-throughput analysis with high specificity and sensitivity, making it suitable for both academic and pharmaceutical research settings focused on human health and nutrition.
