User Guide
Quick-Neuron™ Sensory - Maintenance Medium
Catalog Number: SS-MMIntroduction
Quick-Neuron™ Sensory - Maintenance Medium may be used for the long-term maintenance of human pluripotent stem
cell-derived sensory neurons following differentiation as outlined in the Quick-Neuron™ Sensory - mRNA Kit and Human
iPSC-derived Neurons user guides. Quick-Neuron™ Sensory differentiated cell cultures display typical neurite outgrowthand express a variety of neuronal markers, such as tubulin beta 3 class III (TUBB3) and variety of sensory neuron markerssuch as peripherin (PRPH), islet-1 (ISL1), and brain-specific homeobox/POU domain protein 3A (BRN3A/POU4F1). When
handled and maintained according to the instructions in this user guide, sensory neurons are viable long-term and aresuitable for a variety of characterization and neurotoxicity assays.
Scale:The Quick-Neuron™ Sensory - Maintenance Medium provides sufficient medium for 4 wells of a24-well plate, 1 well of a 6-well plate, or 16 wells of a 96-well plate for up to 2 weeks.

3. Incubate the cultures at 37°C, 5% CO2 for 2 days.
4. Repeat Steps 2-3 every 2-3 days such as on Monday, Wednesday, and Friday for 1 week.

Second Week
1.

Warm Medium N(S1) at room temperature for 20-30 minutes until it no longer feels cold.
Note: If there is an outgrowth of non-neuronal flat cells in the culture (as seen marked by arrows in the sampleimage below) users should continue using Medium N(S1P) in the second week, following the instructions toprepare Medium N(S1P) provided in the “First Week” .

2. Pipet out most of the old medium, but not completely (i.e., just enough to cover the surface of the well), from eachwell and very slowly along the wall of the well, add Medium N(S1) according to the following table.
