The hN2™ Neural Discovery Kit is ideal for pilot experiments and assay optimization. The kit contains the differentiated neural cells and optimized medium plus neural supplement for maintaining the cells in culture.
hN2™ Differentiated Human Neuronal Cells are derived from the WA09 human embryonic stem cells by ArunA Biomedical using a proprietary process under defined feeder & serum free conditions. After differentiation, the cells exhibit a characteristic neuronal morphology and are highly post-mitotic. The cells are >90% β-III tubulin positive, >60% MAP2 positive, <5% Oct-4 positive and express high levels of glutamatergic and GABA-ergic phenotypes. These differentiated neural cells are cryopreserved for ready, convenient use, therefore eliminating lengthy differentiation procedures by the end user.
hN2™ Differentiated Human Neuronal Cells can be cultured in an adherent 96-well format with ArunA’s proprietary culture medium and neural supplement and can be maintained in culture for >2 weeks during which time we have shown them to demonstrate extensive neurite outgrowth and synapse formation.

Cell Type: neural cells
DNA fingerprint: Results are consistent with the presence of a single cell line with no evidence of culture cross contamination. The loci match the DNA fingerprint pattern for the H9 (NIH designation, WA09) hESC line as published in http://stemcells.nih.gov/research/nihresearch/scunit/.
Pathogen testing: This lot was derived from the H9 hESC line that has been tested for Hepatitis B, Hepatitis C, HIV-1, HIV-2, HTLV-I/II, HSV1, HSV2, EBV, and CMV. The H9 cell line has been tested and shown to be negative (performed by GIVF Laboratories). Cells are tested for sterility and mycoplasma contamination.

Neural Progenitor Proliferation
Using hNP1™ Human Neural Progenitors Cells, Molecular Devices' ImageXpress platform can be used to quanitatively measure stimulators and inhibitors of neural progenitor proliferation through high content imaging (HCI). For data generated using this assay, please click here (PDF).

1. Are ArunA’s human cell lines derived from neural blastomas or cancerous cells?
The hN2™ Differentiated Human Neuronal Cells are derived from human embryonic stem cells that are karyotypically stable.
2. Do you have information about the transfection efficiency?
We have not tested transfection or transduction with the hN2™ Differentiated Human Neuronal Cells.
3. Are adult differentiated neurons electrophysiologically active?
Yes, our hN2™ Differentiated Human Neuronal Cells express a variety of ion channels and show some level of electrical activity. A summary of ion channel gene expression and electrophysiological data for the hN2™ Differentiated Human Neuronal Cells is available upon request. Moreover, the hN2™ Differentiated Human Neuronal Cells form an adherent monolayer, making cell-based applications such as calcium imaging, electrophysiology and high content imaging much more straightforward than with neurospheres.
4. What are the phenotypes of your differentiated neural cells?
Our ready-to-use hN2™ Differentiated Human Neuronal Cells are derived using a proprietary differentiation process. Validation standards include: expression of beta-III tubulin (>90% positive) and MAP2 (>60% positive); the cells are mostly post-mitotic. Although we do not routinely test for specific neuronal types, we have found that our process produces ~60% glutamatergic and ~40% GABA-ergic cells with <10% for other cell types (e.g, dopaminergic, serotonergic, cholinergic, astrocytic, etc.).
5. There is a lot of cell death/floating cells in my culture. Is this normal?
6. How long can you keep the differentiated neural cells in culture?
hN2™ Differentiated Human Neuronal Cells may be maintained for up to two weeks in culture. However, some researchers have reported maintaining hN2™ Differentiated Human Neuronal Cells for up to 4-5 weeks in culture.
7. Do the hN2™ Differentiated Human Neuronal Cells, when cultured, only express neuronal cell types?
In our hN2™ Differentiated Human Neuronal Cell cultures, we have observed a variety of neuronal phenotypes, especially after further exposure to additional growth factors used for selective enrichment. Cell types include cholinergic, GABAergic and dopaminergic neurons. Although the majority of the hN2™ Differentiated Human Neuronal Cell culture is comprised of neuronal cell types, astrocytes and oligodendrocytes have also been observed. It's estimated that approximately 10% or less of the cells are glial.
