Primary Cell Line Preparation Service
Creative Biolabs provides professional primary cell isolation, purification, identification, and culture optimization services for mammalian tissues and organs. We obtain high-purity, low-passage primary cells with intact physiological activity, covering neurons, glia, epithelial cells, endothelial cells, immune cells, and other types, for in vitro modeling and functional research.

To initiate the service, clients typically provide Starting Materials such as:
- Specific tissue samples or embryos (if provided by the client).
- Detailed project parameters, including species (murine/rat), anatomical region of interest (e.g., medulla oblongata), and required cell types.
- Desired functional validation criteria (e.g., specific neurotransmitter expression or electrophysiological requirements).

Case Study
The authors compared embryonic and postnatal hindbrain tissues, and chose E17.5 embryos for higher cell yield. They isolated, mixed, and manually counted cells, then evaluated adherence, neurite outgrowth, and MAP2 staining. Results showed hindbrain neurons attached quickly, formed mature networks by 10 DIV, and maintained in vivo-like morphology. This optimized method stably establishes high‑viability primary hindbrain neuron cultures.

FAQs
Q: How do you ensure the purity of specialized neuronal subtypes like GABAergic or Cholinergic neurons?
A: We utilize a combination of regional micro-dissection and immunocapture using specific surface markers. Every batch is validated via ICC for markers such as Glutamate Decarboxylase 67 or Choline Acetyltransferase to ensure the population meets your purity specifications.
Q: Can your service provide tri-culture systems that include microglia?
A: Yes. We can isolate neurons, astrocytes, and microglia from the same regional source. We use specific markers like TMEM119 to ensure microglial identity and can provide them in specific activation states (M1 or M2) depending on your research needs.
Q: What is the typical lifespan of these primary cells once they arrive at my lab?
A: While primary neurons do not divide, our optimized protocols and media recommendations allow for stable maintenance for 2-4 weeks, depending on the cell type. We provide detailed guidelines on substrate coating to maximize this window.
Q: How do you handle the risk of batch-to-batch variability inherent in primary tissue?
A: We minimize variability through standardized "Cold-Chain" processing and rigorous QC. Each lot is accompanied by a technical datasheet detailing the exact marker expression and viability, allowing you to normalize data across experiments.
Q: Do you offer custom isolation for species other than mouse or rat?
A: Yes. While murine models are standard, we have the capacity for custom isolation from other species upon request. Please inquire to discuss the ethical and technical feasibility of your specific model.
Creative Biolabs provides a suite of primary cell services, including custom isolation, phenotypic characterization, and the development of complex 3D or tri-culture models. We specialize in "hard-to-isolate" regions, providing researchers with the tools needed for high-impact discovery.
