A marker for airway and alveolar progenitor cells

Anti CPM, Monoclonal Antibody (WK), Red Fluorochrome(635)-conjugated

Carboxypeptidase M(CPM) is an enzyme present on the surface of the cell membrane that catalyzes cleavage of C-terminal arginine and lysine residues from polypeptides and proteins.
Recent studies have reported that CPM can be used as a marker for airway, alveolar and hepatic progenitor cells. This product is Anti CPM, Monoclonal Antibody conjugated with Red Fluorochrome (635).

Product outline

Formulation Phosphate buffer containing 0.05w/v% sodium azide
Concentration 0.54 mg/mL (initial measured value)
Subclass Mouse IgG2b
Applications (flow cytometry) 1:10

Example of Use

Human iPS cells were differentiated into lung progenitor cells. The differentiated cells were dissociated, stained with this newly developed product, and sorted with flow cytometry. After sorting, immunostaining was performed on each cell population.
