This original and genuine B-27 Supplement is a cGMP-manufactured, serum-free solution designed to ensure the consistent, reliable, and high-quality growth of embryonic, post-natal, and adult hippocampal neurons, as well as other CNS neurons. With a proven track record, B-27 Supplement supports both low- and high-density cultures, ensuring viability in serum-free media. Each batch undergoes rigorous performance testing to confirm its ability to successfully culture hippocampal neurons, providing you with the confidence and dependability you need for your research.

  • Dependable consistency—every lot is performance-tested for reliable results
  • High quality—cGMP manufacturing provides the highest standards of quality
  • Versatile usage—ideal for use with serum-free media such as Neurobasal Medium or Neurobasal-A Medium, without the need for an astrocyte feeder layer. Supports the growth and viability of neurons, as well as many other cell types differentiated from PSCs.
  • Proven performance—a proprietary formulation; the first and most cited neuronal cell culture supplement, trusted by researchers worldwide

Choose B-27 Supplement for the authentic solution that sets the standard for neuronal cell culture.

Frequently asked questions (FAQs)

Can B-27 supplement be filtered?

Yes, the protein content in this product is high enough so filtering through a low protein binding filter as a 50X or 1X in solution should not be a problem.

Can Neurobasal Medium alone or Neurobasal Medium supplemented with B-27 supplement be frozen to extend product shelf life?

No, it is not recommended to freeze media due to the potential of precipitates forming upon thaw. Inorganic salts and amino acids in the formulation may come out of solution when exposed to temperature fluctuations. These precipitates will not go back into solution easily once formed.

What supplements should I use with Neurobasal or Neurobasal-A medium?

Neurobasal and Neurobasal-A media (for postnatal and adult neurons) allow for long-term maintenance of neuronal cells without the need for an astrocyte feeder layer. These media should be supplemented with either serum or a serum-free supplement, plus 0.5mM L-glutamine. B-27 supplement is a serum-free supplement that comes as a 50X concentrate in a 10ml volume. This is enough supplement for 500ml of media. Fetal, postnatal, and adult neural cultures can be grown in the appropriate Neurobasal medium supplemented with B-27 supplement .

We also have two other supplements. One is called G-5 and is for growth and expression of glial cells (normal and tumor) of astrocytic phenotype. This comes in a 1ml size, at a 100X concentration. The other supplement is called N-2 and is for growth and expression of post-mitotic neurons and tumor cells of neuronal phenotype. This comes in a 5ml size, at a 100X concentration.

For more information on Neurobasal media, search "Neurobasal" from our website home page.

Which media system should I use for primary culture of P0- or P1-derived mixed hippocampal cells?

We recommend using Neurobasal Plus Medium with B-27 Plus Supplement for long-term culture of mixed hippocampal cells. For short-term culture of a pure population of hippocampal neurons, we would recommend using Neurobasal-A Medium with B-27 Supplement.

Do you offer B-27 supplements with and without insulin?

Yes, we do offer B-27 Supplement, minus insulin (Cat. Nos. A1895601 and A1895602). All our other B-27 supplements do contain insulin.
