Used in research settings to quantify levels of phosphatidylinositol-specific phospholipase D (PHLD) in bovine samples. This ELISA kit enables scientists to study enzyme activity and expression in cellular signaling pathways, particularly those involved in cell growth, membrane trafficking, and inflammatory responses in cattle. It supports investigations in veterinary science, reproductive biology, and disease mechanisms where phospholipase D plays a regulatory role. The assay provides a sensitive and specific method for measuring PHLD protein concentration in tissue homogenates, cell lysates, or biological fluids, facilitating high-throughput analysis in experimental and diagnostic research.
