Used in research settings to quantify expression levels of the Human Paternal Expression Gene 2 (PEG2) in biological samples. This ELISA kit enables detection and measurement of PEG2 protein concentrations, supporting studies in epigenetics, genomic imprinting, and developmental biology. It is commonly applied in investigations related to paternal gene inheritance, placental development, and certain cancers where imprinted genes may play a role. The kit provides a reliable and sensitive method for monitoring PEG2 in cell lysates, tissue extracts, and serum samples, aiding both academic and clinical research.
