SEZ6 Antibody, FITC conjugated

What is SEZ6 and why is it a target of interest in neuroscience and oncology research?

SEZ6 (Seizure protein 6 homolog) is a cell-surface protein that plays crucial roles in neuronal development and function. It is involved in cell-cell recognition, neuronal membrane signaling, and is particularly important for maintaining the balance between dendrite elongation and branching during the development of complex dendritic arbors.

• Co-localization markers: Include lysosomal markers such as LAMP1 fused to fluorescent proteins (e.g., mRUBY) to determine subcellular localization after internalization. Established protocols use cells expressing LAMP1-CmRuby2 to visualize lysosomal co-localization with internalized SEZ6 antibodies .

• Imaging parameters:

  • Use nuclear counterstains (e.g., NucBlue) to facilitate cell identification

  • Image within 10 minutes after staining for baseline (time zero) measurements

  • Employ automated epifluorescent microscopy (e.g., Cell Insight CX5) for consistent image acquisition

• Controls: Include human IgG isotype controls to determine background and non-specific internalization rates.

The experimental workflow should follow this sequence:
