Used in biomedical research to quantitatively measure Laminin α3 levels in human tissue extracts, cell culture supernatants, or biological fluids. This kit is particularly useful in studies related to skin biology, wound healing, and diseases involving basement membrane defects such as junctional epidermolysis bullosa. It enables researchers to assess Laminin α3 expression in cancer progression, especially in tumors where cell adhesion and migration are altered. The assay supports investigation into epithelial-stromal interactions and regenerative medicine applications involving extracellular matrix components.
