The standard for neuronal cell culture
More than 25 years ago, the first commercially available, serum-free supplement for neural cell culture, Gibco B-27 Supplement (50X) was developed and with Gibco Neurobasal Medium has set the standard in neuronal cell culture reagents. Originally designed for culturing primary neurons, the classic B-27 Supplement and nutritive variants have been widely adapted and successfully used in many other applications and cell types, including growth and maintenance of neural stem cells and PSC-derived neurons, 3D cell culture and disease modeling.
The most-referenced neuronal cell culture supplement just got better
To further meet the growing needs of researchers, an optimized formulation of the classic B-27 Supplement was developed in 2018 for improved long-term neuronal survival, functionality and maturation of primary rodent neurons and stem cell-derived neurons. See below section: Superior survival, maturation, and neural network activity and learn more about B-27 Plus Neuronal Culture System.

Make the switch to the next-generation B-27 Supplement
The desire for more reliable and biologically relevant models has increased, so too has the necessity for a next-generation media system that can maintain and mature optimal densities of functional neurons over longer periods of time in vitro.
The next-generation Gibco B-27 Plus Neuronal Culture System, composed of B-27 Plus Supplement and Neurobasal Plus Medium, improves upon the classic culture environment through raw material and manufacturing upgrades and minor formulation modifications. Together, these small changes yield big results in the maintenance and maturation of primary neurons to offer the following improved benefits:
- Increased neuronal survival by more than 50% vs competitors
- Improved neurite outgrowth
- Improved electrophysiological activity and maturation
Advancing 3D neural cell culture
Complex 3D models are becoming a favored system to study embryonic development and disease to more faithfully recapitulate in vivo neural architectures and physiology than traditional 2D cultures. A plethora of applications, spanning a wide range of cell types have benefited from B-27 supplements.
Scientists are discovering that B-27 supplements benefit more than just neural cell types in 2D adherent cultures. See Table 1 Citations for the use of B-27 Supplement in 3D culture.
Figure 2. Neural spheroid maturation. (A) Phase contrast images of neural spheroids at 21 days cultured in “classic” B-27 or B-27 Plus (not shown) supplement to yield spheroids of similar size and shape. (B) Gene expression analysis using TaqMan PCR assay shows increased expression level of genes related to functional synapses and neurotransmitter trafficking with the addition of CultureOne Supplement (Cat. No A3320201).
Figure 3. Neural stem cells (NSCs) produce spheroids in B-27 Supplement. NSCs generated from Gibco Human Episomal iPSC Line (Cat No. A18945), or H9 hESC, were cultured in maturation medium consisting of either B-27 Supplement with Neurobasal Medium (Cat No. 21103049) or in B-27 Plus Neuronal Culture System. Cells seeded in Gibco Nunclon Sphera 96-Well Microplates (Cat No. 174925) across a range of densities formed single neural spheroids within 24 hours.
