Detection of Oligodendrocyte Marker O1 in Rat Differentiated Cortical Stem Cells by Flow Cytometry. Rat differentiated cortical stem cells were stained with Mouse Anti-Human/Mouse/Rat/Chicken Oligodendrocyte Marker O1 Monoclonal Antibody (Catalog # MAB1327, filled histogram) or mouse IgM isotype control antibody (open histogram), followed by Allophycocyanin-conjugated Anti-Mouse IgM Secondary Antibody (Catalog # F0117).

Oligodendrocyte Marker O1 in Rat Cortical Stem Cells. Oligodendrocyte Marker O1 was detected in immersion fixed 7 day differentiated rat cortical stem cells using Mouse Anti-Human/Mouse/Rat/Chicken Oligodendrocyte Marker O1 Monoclonal Antibody (Catalog # MAB1327) at 1 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgM Secondary Antibody (red; Catalog # NL019) and counterstained with DAPI (blue). Specific staining was localized to oligodendrocytes. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Background: Oligodendrocyte Marker O1
Oligodendrocytes are myelinating cells in the central nervous system (CNS) that form the myelin sheath of axons to support rapid nerve conduction. Oligodendrocyte Marker O1 recognizes a glycolipid antigen that is expressed on the surface of late oligodendrocyte progenitors. It has been commonly used in conjunction with Oligodendrocyte Marker O4 antibody to define immature oligodendrocyte (1-6). Progenitors that are O4 antigen-positive and O1 antigen-negative have been shown to differentiate into O1 antigen-positive oligodendrocytes in vitro (7).
