Add the following small molecules to small volumes immediatly before media addition, to a final concentration of 10 ng/mL:
BDNF, from 1,000x stock (10,000 ng/mL)
CNTF, from 1,000x stock (10,000 ng/mL)
GDNF, from 1,000x stock (10,000 ng/mL)
FGF, from 10,000x stock (100,000 ng/mL)
RepSox, if RR, from 1000x stock (7.5mM)
Note
200mM glutamine is the same as Glutamax
We do not usually use FBS or Pen/Strep

Sorting/Collection media
Used for cell sorting. Use DMEM/F12 for flow sorting and DMEM/F12 + 10% FBS for collection to help make cells happier. It is possible to use whatever though because you will have to spin-down and resuspend in the correct media (i.e. N3) anyways. You will want to include Pen/Strep as it will greatly reduce the amount of contamination.

Motor neuron dissociation media
Used for dissociating iMNs or primary motor neurons (embMN) harvested from spinal cords for plating/sorting. Add 50 µL/96-well, let sit in 37°C for ~15 min. Lightly tap plae to see if cells are dissociating.

HEPES-buffered DMEM
For use during lentivirus or retrovirus production in HEK293T cells. We use HEPES Sigma-Aldrich (H3375).

Note
When NBW did this on 7/10/23, I did 41.46 g HEPES + 150 mL water. The HEPES takes up a lot of volume so I would dissolve in 100 mL ELGA-filtered water, then check volume and increase to 150 mL.
At the beginning, pH = 5.45 and I had to add 8.9 mL 4N NaOH to get to pH = 7.00.
