Lipophilic carbocyanine dyes like our original CellBrite™ Cytoplasmic Membrane Stains have been used to stain neuronal cells in culture for several weeks, and in vivo for up to a year. The dyes do not appreciably affect cell viability, and do not readily transfer between cells with intact membranes, allowing cell migration and tracking studies in mixed populations. Over time, the dyes will be internalized and become intracellular as membranes turn over. Long term stability of labeling may vary between cell types, depending on rates of membrane turnover or cell division.
CellBrite™ Fix Membrane Stains label the cell surface covalently. Like original CellBrite™ dyes, they are non-toxic and do not readily transfer between cells, but will be internalized and become intracellular as membranes turn over.← FAQs
