The MSC Characterization Antibody Panel is designed for the phenotypic analysis of human mesenchymal stromal cells (MSCs). This kit contains three fluorochrome-conjugated antibodies for the identification of human MSCs, and a fluorochrome-conjugated antibody for the identification of non-MSCs. When measured by flow cytometry, ≥ 95% of the MSC population must express CD73, CD90, and CD105, and these cells must lack expression (≤ 2% positive) of CD45. These reagents provide single-step labeling for the verification of human MSCs.The MSC Characterization Antibody Panel can be used to identify human MSCs derived from various tissues such as bone marrow MSCs, pluripotent stem cell-derived mesenchymal progenitor cells, adipose-derived MSCs, dental pulp-derived MSCs, and umbilical cord-derived MSCs.
