做为一般性的参考方案，我们推荐您使用Gibco B-27添加剂来培养神经干细胞，海马及其他类型的CNS神经元。
-对于来自PNS和CNS中的神经母细胞瘤或有丝分裂后的神经元，可添加Gibco N-2添加剂。
-对于原代胶质细胞（星形胶质细胞）或具有星形胶质细胞表型的肿瘤细胞系（星形胶质细胞和胶质细胞瘤），或少突胶质细胞，可使用Gibco G-5添加剂。
Neurobasal培养基专门针对胚胎神经元和出生前神经元的培养体系进行了优化。Neurobasal-A培养基专为培养出生后神经元与成年脑神经元进行了优化。这两类培养基仅在渗透压上有所区别。
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.

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.

Instructions for growing adult neurons can be found in the Neurobasal-A Medium product insert. You can also refer to the following publication for growing adult neurons:
• Isolation and Culture of Adult Rat Hippocampal Neurons by Brewer, G.J., J. Neuroscience Methods 71 (1997), 145-158.
We do not know at what age postnatal neurons require FGF and a higher osmolality medium, or how this could vary based on the species from which the neural tissue is isolated. Without this knowledge, we generally recommend switching to the Neurobasal-A Medium for isolates from animals above 1 week of age. You will need to determine if the Neurobasal-A Medium is optimal for neurons you have from one day old rats.
Further, the addition of bFGF can increase the viability of neurons of any age. Therefore, caution needs to be made in impure neuronal cell culture as bFGF can increase the proliferation of non-neuronal cells. We recommend a pilot experiment to test the impure culture in the presence and absence of bFGF.

We recommend adding B27 and b-FGF to Neurobasal-A Medium to grow adult neurons.

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.

As a general guideline, we recommend using Gibco B-27 Plus Supplement to culture neural stem cells, hippocampal, and other CNS neurons.
- For neuroblastomas, or post-mitotic neurons from both PNS and CNS, Gibco N-2 Supplement can be used.
- For primary glial cells (astrocytes) or tumor cell lines of astrocytic phenotype (astrocytes and gliomas), or oligodendrocytes, Gibco G-5 Supplement can be used.
Neurobasal Medium is optimized for prenatal and fetal neurons. Neurobasal-A Medium is optimized for growing postnatal and adult brain neurons. These two media differ only in osmolality.
