Used in biomedical research to quantify levels of syndecan-1, a cell surface proteoglycan, in biological samples such as serum, plasma, or tissue extracts. The kit enables researchers to study syndecan-1's role in cellular adhesion, inflammation, and cancer progression. It is particularly useful in assessing endothelial damage and glycocalyx degradation in conditions like sepsis, trauma, and cardiovascular diseases. The ELISA format allows for high sensitivity and specificity, making it suitable for both clinical and experimental settings where precise measurement of syndecan-1 concentration is required.
