Cell Line Passage Stability Evaluation Service
The Needs of Cell Line Passage Stability Evaluation
Cell lines are invaluable tools in research and therapeutic applications. However, with each passage, cells are subjected to environmental and manipulative stresses that can lead to genetic mutations and phenotypic shifts. This evolutionary pressure can result in a heterogeneous population that no longer represents the original cell culture isolate. The following points underscore the critical need for cell line passage stability evaluation:
Genetic and Phenotypic Alterations
Studies have demonstrated that high passage numbers can lead to alterations in cell morphology, growth rates, response to stimuli, protein expression, and transfection efficiency.
Regulatory Requirements
Regulatory guidelines by authorities such as the FDA and WHO mandate the evaluation of genetic stability in cell lines used for the production of biotechnological products. These guidelines emphasize the need for thorough testing of master cell banks (MCBs) and working cell banks (WCBs) to confirm the integrity and identity of the cells over time.
Cell Line Passage Stability Evaluation Service at Creative Biolabs
At Creative Biolabs, we recognize the paramount importance of cell line integrity and have designed a robust and thorough cell line passage stability evaluation service. Our expert team combines state-of-the-art technologies with a profound understanding of regulatory requirements to deliver unparalleled service quality.
Service Contents
Our comprehensive service includes the following key components:
Genetic Stability Testing
Using advanced molecular approaches such as quantitative PCR (qPCR), digital PCR (dPCR), and high throughput sequencing (HTS), we assess the genetic stability of cell lines across multiple passages. These techniques offer high sensitivity and precision, enabling the detection of minute genetic variations.
Functional Stability Testing
Functional characteristics such as phagocytosis and nitric oxide production are crucial for certain cell lines. Our service includes rigorous testing to ensure these functional traits remain stable over successive passages.
Viral Contamination Screening
We provide thorough viral contamination screening to detect both endogenous and exogenous viral factors, ensuring the safety and integrity of the cell lines.
Phenotypic Stability Assessment
We evaluate the stability of phenotypic traits through the analysis of cell morphology, growth rates, and the expression of phenotypic markers.

Frequently Asked Questions
Q1: What are the risks of high passage numbers for cell lines?
A1: High passage numbers can lead to genetic drift, alterations in phenotype, and reduced reproducibility of experimental results. It can also impact the efficacy and safety of biopharmaceutical products derived from these cell lines.
Q2: How long can a cell line be cultured?
A2: The limit of the number of passages a cell line can undergo varies depending on the cell type. For continuous cell lines, there is essentially no limit, although phenotypic and genotypic changes may occur over time. Finite cell lines derived from primary cells typically senesce after a certain number of population doublings.
