The mouse monoclonal antibody W5C5 recognizes an extracellular epitope of SUSD2, a type I transmembrane protein expressed on mesenchymal stem-like cells. This antibody selectively binds to a MSCs in both bone marrow and endometrium or tonsil, and can be used for their identification and isolation.
纯化方法
Purified antibody is conjugated with activated allophycocyanin (APC) under optimum conditions and unconjugated antibody and free fluorochrome are removed by size-exclusion chromatography.
Sushi domain containing 2,SUSD2 (sushi domain containing protein 2) is a type I transmembrane protein, that serves as an important marker of bone marrow-derived mesenchymal stem-like cells (bone marrow stromal cells). These pluripotent cells are important for techniques of autologous cell therapy, and can be collected from e.g. endometrium, or palatine tonsil. SUSD2 seems to be a tumor supresor, and is down-regulated in colon cancer tissues, whereas it is highly expressed e.g. in breast cancer.
