Definition
Separating and expanding a population derived from a single cell (key to stable cell lines, edited cell lines, and monoclonal antibody workflows).
Why it matters
For scientific teams:
- Ensures experimental results are not confounded by mixed genotypes.
- Enables clear genotype–phenotype relationships.
- Required for stable cell line and edited clone generation.
For decision-makers:
- Supports regulatory expectations for monoclonality documentation.
- Reduces downstream risk in cell line development programs.
- Prevents costly rework caused by heterogeneous clones.
FAQ
Q: When is clonal isolation required?
A: It is required for cell line development, gene editing workflows, and monoclonal antibody production.
Q: Is clonal isolation the same as monoclonality?
A: No. Clonal isolation is the process; monoclonality is the evidence that the process succeeded.
