Product Summary for N-2 MAX Media Supplement (100X)

Kit Summary

For culturing neurons, neural progenitors, and stem cells.

Key Benefits

  • Optimized for neural and stem cell cultures
  • Recombinant Human Insulin ensures low experimental variability
  • Consistent, chemically-defined, and serum-free formulation
  • Ideal for NPC derivation, maintenance, and differentiation
  • Enhances performance of stem cell differentiation protocols
 

Why Culture Neurons under Fully Defined Conditions?

Serum-free, defined media are routinely used as an alternative to standard serum-containing media in order to reduce unwanted experimental variability.

Uncontrolled variables commonly associated with serum-supplemented media, such as indeterminate levels of vitamins, hormones, and growth factors are eliminated, and the potential for contamination by infectious agents is reduced when cells are cultured under defined conditions. In addition, serum-free media offers researchers the ability to specifically design the culture media for a particular experimental question.

The N-2 MAX Media Supplement:

  • Contains high quality factors to support reproducible and efficient NPC expansion.
  • Is fully defined to reduce unwanted experimental variability.
  • Has been developed and optimized using neural progenitor cells.

Contents

Supplied as a 100X concentrate in water, this media supplement contains the following high quality factors to support neural cell culture:

 
Component Amount (mg/mL)
Recombinant Human Insulin 2,500 µg/mL
Human Transferrin 10,000 µg/mL
Putrescine 1,611 µg/mL

Neural Progenitor Cells Expanded with N-2 MAX Media Supplement Express Nestin and SOX2.Rat Cortical Stem Cells (Catalog # NSC001) were cultured for 7 days in media supplemented with 1X N-2 MAX Media Supplement (Catalog # AR009) and 20 ng/mL of Recombinant Human FGF basic (Catalog # 233-FB). The cells were stained with a PE-conjugated Mouse Anti-Human Nestin Monoclonal Antibody (Catalog # IC1259P; red histogram), a PE-conjugated Mouse Anti-Human/Mouse SOX2 Monoclonal Antibody (Catalog # IC2018P; green histogram), or a PE-conjugated Mouse IgG2AIsotype Control (Catalog # IC003P; open histogram). Under these conditions, cells were shown to express high levels of Nestin and SOX2, two established markers of neural multipotency.

Background: Neural Stem Cells

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.
