Used in life science research to quantitatively measure Apelin13 protein levels in mouse biological samples such as serum, plasma, and tissue homogenates. This ELISA kit is particularly useful in studies related to cardiovascular function, angiogenesis, and metabolic regulation, as Apelin13 is involved in these physiological processes. It enables researchers to monitor changes in Apelin13 expression under experimental conditions, supporting investigations into heart disease, diabetes, and inflammatory conditions in mouse models. The assay provides high sensitivity and specificity, making it suitable for detecting low concentrations of the protein in small sample volumes.
