Used in research settings to quantify levels of the mouse paternal expression gene 2 (PEG2) protein in biological samples such as tissue lysates or cell culture supernatants. This ELISA kit enables scientists to study gene regulation, genomic imprinting, and developmental processes in mouse models. It is particularly useful in reproductive biology, embryology, and epigenetics research where accurate measurement of PEG2 protein expression is required. The assay provides high sensitivity and specificity, allowing detection of subtle changes in protein levels across experimental conditions. Not intended for diagnostic or therapeutic use.
