Used in biomedical research to quantify levels of Prolyl 4-hydroxylase β polypeptide (P4HB) in biological samples such as cell lysates, serum, or tissue extracts. This ELISA kit is particularly valuable in studies related to protein folding, endoplasmic reticulum stress, and oxidative processes in cells. It supports research in cancer, neurodegenerative diseases, and metabolic disorders where P4HB expression is altered. The assay enables high-sensitivity detection, allowing researchers to monitor disease progression or evaluate therapeutic responses in experimental models.
