Summary for N21-MAX Vitamin A Free Media Supplement (50X)
Kit Summary
For controlled neural stem and progenitor cell expansion.
Key Benefits
- Optimized for neural stem cell expansion

- Rigorous quality control testing ensures consistency across experiments
- Eliminates the need for an astrocyte feeder layer
- Is nutrient-rich, serum-free, and fully defined
Why Culture Neurons in Serum-Free N21-MAX Media Supplement?
The N21-MAX Vitamin A Media Supplement is a serum-free and fully-defined media formulation that is optimized for the consistent health and superior growth of neural stem/progenitor cells. The N21-MAX Vitamin A Free Supplement limits NSC differentiation by reducing unwanted retinoic acid production in cell culture medium. It can also be used to mature and maintain healthy primary neurons in culture.
N21-MAX media supplements were designed to eliminate uncontrolled variables, such as those found in both serum-containing media and in some commercial serum-free neuronal supplements. Use of undefined media supplements can confound neuronal growth and maturation. N21-MAX media supplements contain a cocktail of factors optimized for neural stem cell expansion, neuronal survival, and synaptic maturation. Each lot of N21-MAX Media Supplement is tested on primary hippocampal neurons to ensure consistent performance for the user.
The N21-MAX Vitamin A Free Media Supplement:
- Is fully defined and quality tested to reduce unwanted experimental variation.
- Contains factors qualified to the expansion of NSCs in vitro.
- Limits retinoic acid production to reduce unwanted NSC differentiation.
- Does not require an astrocyte feeder layer.

Precautions
This product contains human transferrin. This transferrin was purified from donor plasma and tested at the donor level using an FDA licensed method and found to be non-reactive for anti-HIV-1/2 and Hepatitis B surface antigen.
Neural stem cells provide an excellent model for research focused on neural development and neurological disorders. R&D Systems offers ready-to-use primary cortical stem cells isolated from E14.5 Sprague-Dawley rats. In addition, primary mouse cortical stem cells isolated from E14.5 CD-1 mice are available. Every lot of R&D Systems Cortical Stem Cells is validated for a high level of Nestin expression and the capacity for multi-lineage differentiation into astrocytes, neurons, and oligodendrocytes. Our cortical stem cells are tested to ensure highest quality and lot to lot consistency. Both rat and mouse Cortical Stem Cells can be optimally expanded as monolayers or neurospheres.
To complement the use of primary neural stem cells, we offer a range of supportive products, including culture media which is specifically optimized for use with neural stem cells. We offer kits to promote the in vitro proliferation of neural precursors, and kits to differentiate neural stem cells into dopaminergic neurons or oligodendrocytes. In addition, kits are available which contain panels of antibodies designed to monitor the differentiation and identification of neural precursors, astrocytes, neurons, and oligodendrocytes.
