      DescriptionMilli-Mark™ ChromaPan Neuronal Marker-OMC
      Background InformationThe Milli-Mark™ ChromaPan Neuronal Marker-OMC is a complete multi-species neuronal antibody blend with an open mouse channel (OMC) that specifically detects axons, dendrites, and cell bodies with different fluorophores. The Multi-species Primary Antibody blend does not have a mouse IgG; this allows the researcher to colocalize their own mouse IgG (against their target protein) to the neuronal cytoarchitecture.

      Antibodies to neuronal proteins have become critical tools for identifying neurons and discerning morphological characteristics in culture and complex tissue. Neuron-specific antibodies are convenient precision tools useful in revealing cytoarchitecture, but are limited to the protein target distribution within the neuron, which may differ greatly from nucleus to soma to dendrite and axon. To achieve as complete a morphological staining as possible across all parts of neurons, Millipore has developed a multi-species primary antibody blend that reacts against key somatic, dendritic, and axonal proteins distributed across the neuronal architecture that can then be detected by a single multi-species secondary antibody blend containing discrete fluorophores. As a result, different morphological features (somatic, dendritic, and axonal) are illuminated in different colors: The somato-dendritic cytoarchitecture is detected with DyLight® 649 conjugated secondary, and the somato-axonal cytoarchitecture is detected with cyanine 3 conjugated secondary antibody. The primary antibody blend does not contain any mouse IgGs. The researcher can add a mouse IgG against their target protein which can be detected with the secondary antibody blend provided, by a DyLight® 488 conjugated secondary against Mouse IgG. This pan-neuronal antibody cocktail has been validated in a variety of cell and tissue cultures, giving researchers a convenient and specific qualitative and quantitative tool for studying neuronal morphology.

      Key Applications
      • Immunocytochemistry
      • Immunofluorescence
      Application NotesImmunocytochemistry:
      1. Culture neurons as desired. When ready, gently wash with PBS and fix cells with 4% paraformaldehyde in PBS, 5-15 min at room temp (RT).
      2. Wash with PBS, 3 x 5min each, at RT and block with 1X blocking buffer for 1 hr at RT.
      Note: The blocking buffer provided is supplied as a 5X concentrate. Dilute the concentrate to 1X strength using Milli-Q™ water. For example, add 20 ml of Milli-Q™ water to 5 ml of 5X blocking buffer.
      3. Incubate cells with ChromaPan Multi-species Primary Antibody blend for 2hr at RT (dilute antibody 1:100 to 1:200 in blocking buffer). Optimal working concentrations must be determined by the end user.
      Optional: Mouse IgG against target protein can also be added to the ChromaPan primary antibody mixture. Optimal working conditions must be determined by the end user. If mouse IgG is added skip step 4.
      4. Wash with PBS, 3 x 5min each, and incubate cells with mouse IgG against target protein. Optimal working conditions must be determined by the end user.
      5. Wash with PBS, 3 x 5min each, and incubate cells with Multi-species Secondary Antibody blend (1:150 in blocking buffer) for 1hr at RT (validated with Chroma Pan to produce minimal background). Optimal working concentrations must be determined by the end user.
      Optional: DAPI (1:1000) can also be added to the secondary mixture. If DAPI is added skip step 6.
      6. Wash with PBS, 3 x 5min each, and incubate cells with DAPI (1:1000 in blocking buffer) for 5min at RT. Optimal working concentrations must be determined by the end user.
      7. Wash with PBS, 3 x 5min each, and cover slip with LIGHT DIAGNOSTICS Mounting Fluid (Catalog No. #5013). View using fluorescent microscope with appropriate filter.
