Used in biomedical research to quantitatively measure Prostate Acid Phosphatase (PAP) levels in biological samples such as serum, plasma, or tissue homogenates. This ELISA kit is particularly useful in studies related to prostate cancer, as PAP serves as a historical biomarker for prostate function and disease progression. Researchers use this kit to monitor changes in PAP concentration in response to treatment, to assess prostate tumor activity, or to support diagnostic development. It is intended for research use only and not for diagnostic procedures in clinical settings. The assay enables high sensitivity and specificity, making it suitable for detecting low levels of PAP in small sample volumes.
