Dear Letizia and Bill,
we had also severe problems with the neurons from rat embryos.
This changed a lot, when we were testing Neurobasal A medium from
Invitrogen (please remember, I do not intend to do a PR show here,
it's only help!!!).
We tried many things, like low oxygen, low osmolarity, sandwich
coverslip culture, astrocyte feeding layer (which seems to be really
great, but we have problems with the layer...), different media from
many companies and suffered through all this, sometimes great
cultures, sometimes only dead cells in the well / dish.
After all we started using this literature-source as background:
Acute Effects of Ethanol on Kainate Receptors with Different Subunit
Compositions, Valenzuela, Cardoso2, JPET March 1, 1999 vol. 288
no. 3 1199-1206
http://jpet.aspetjournals.org/content/288/3/1199.abstract
This has nothing to do with our research, but is providing very good
and stable culture results.
I can provide you our actual protocol, if you want, but this should be
done out of the list.
But remember, that the pattern of morphology/ type of the neurons in
this culture is quite different from embryonal cultures.
Best regards
Thomas
