Replicating Nature. Redefining the Benchtop.
The future of medicine is only as stable as the environment you build for it.
In the elite regenerative medicine and stem cell labs of Hong Kong research comunity, standard coatings are no longer enough. Alpha Labs Limited is proud to be your Hong Kong gateway to BioLamina—the world leader in chemically defined, animal-origin-free matrices that actually mimic the human body.
By utilizing the power of Biolaminin®—the primary isoform of the human basement membrane—BioLamina allows you to grow primary cells and pluripotent stem cells without the "biological noise" of undefined coatings. Whether you are scaling up for Cell & Gene Therapy (CGT) or conducting high-fidelity disease modeling, we provide the specialized laminins required to ensure phenotypic stability, improved cell survival, and truly reproducible results

The Power of Biolaminin® Technology
1. Defined & Animal-Free Culture
- Biolaminin® 521 LN: The premier substrate for the robust expansion of human ES and iPS cells. It allows for single-cell seeding without the need for ROCK inhibitors, ensuring high survival rates and genetic stability.
- Xeno-Free & GMP Grades: Essential for researchers moving from basic discovery to clinical-grade regenerative medicine, providing a seamless regulatory path.
2. Tissue-Specific DifferentiationLaminins are the most important proteins in the basement membrane. Different organs require different laminin isoforms:
- Biolaminin® 111: Specifically designed for hepatocytes and intestinal cell research.
- Biolaminin® 211: The ideal choice for culturing cardiomyocytes and skeletal muscle cells.
- Biolaminin® 411 & 511: Optimized for vascular and endothelial cell research.
3. Overcoming "Feeder-Cell" Limitations
- Replace unpredictable substrates like Matrigel® with a chemically defined, recombinant protein. BioLamina eliminates the "batch-to-batch" variation that often ruins long-term stem cell experiments.
4. Biosilk™: The Recombinant 3D Scaffold
- Mimicking the ECM: Biosilk is a unique, recombinant spider-silk protein that self-assembles into a microfiber network. It provides a stable 3D framework that supports cell attachment and mechanical stability without the risk of immunogenicity.
- No Necrotic Cores: Unlike thick gel droplets, the Biosilk microfiber network allows for superior oxygen and nutrient diffusion, enabling the growth of larger, healthier organoids without center cell death.
- Ready-to-Use 3D Niche: Biosilk can be "functionalized" with specific laminin isoforms. Biosilk 521 is pre-integrated with Biolaminin 521, creating a perfect 3D environment specifically for pluripotent stem cells (PSCs).
- Tissue-Specific Engineering: Researchers can customize their 3D environment by adding different laminins (e.g., Biolaminin 111 for liver organoids or 211 for muscle) to the Biosilk scaffold to drive lineage-specific differentiation.
- Neural & Brain Models: The combination of Biosilk and Biolaminin 521/111 has been successfully used to create "brain-like" 3D neural tissues that show spontaneous functional activity and uniform neuroepithelial patterning.
- Disease Modeling & Drug Discovery: Because the system is chemically defined, it eliminates the "batch-to-batch" noise of animal-derived gels, providing the clean data needed for high-throughput drug toxicity testing.

F&Q
- Q: Is Biolaminin® 521 compatible with E8 or mTeSR™1 media?
- A: Yes. Biolaminin® 521 is chemically defined and works seamlessly with all major commercial PSC media, often improving the attachment and expansion rates compared to standard coatings.
- Q: Can I use the same coating concentration for all cell types?
- A: No. While a standard concentration of 0.5 ug/cm2 is common, specific cells like hepatocytes or cardiomyocytes may require optimization between 0.1 ug/cm2 and 2 ug/cm2.
- Q: Does the "LN" in your product names refer to the full-length protein?
- A: Yes. Biolaminin® products are intact, full-length human recombinant proteins, which provide the authentic biological signals that truncated fragments or animal-derived mixtures lack.
