The Immortalized Human Dopaminergic Neuronal Precursor Cells, also known as the Lund Human Mesencephalic (LUHMES) cell line, is a subclone of the tetracycline-controlled, v-myc-overexpressing human mesencephalic-derived cell line MESC2.10. This cell line is unique in that it can be differentiated to acquire a dopaminergic neuron-like phenotype under appropriate growth conditions. LUHMES expresses functional dopamine transporter (DAT), vesicular monoamine transporter (VMAT-2), tyrosine hydroxylase (TH) and the neuronal form of ?-III tubulin after differentiation. In addition to retaining dopaminergic neuronal-specific markers, LUHMES also exhibit electrophysiological properties, thus making this cell line a valuable neuronal model for neurodevelopmental studies, disease modelling and neuropharmacology. May take 4 to 5 days for cells to recover in culture.

1. All test parameters provided in the CoA are conducted using abm's standardized culture system and procedures. The stated values may vary under the end-user's culture conditions. Please verify that the product is suitable for your studies by referencing published papers or ordering RNA (0.5 ?g, Cat.# C207, $450.00) or cell lysate (100 ?g, Cat.# C206, $600.00) to perform preliminary experiments, or alternatively use our Gene Expression Assay Service (Cat# C138). All sales are final. 2. We recommend live cell shipments for ease of cell transfer and this option can be requested at the time of ordering. Please note that the end-user will need to evaluate the feasibility of live cell shipment by taking into account the final destination's temperature variation and its geographical location. In addition, we thoroughly test our cell lines for freeze-thaw recovery. If frozen cells were received and not recovered in your lab under the exact, specified conditions (using recommended culture vessel, media, additional supplements, and atmospheric conditions), a live cell replacement is possible at a cost (plus shipping). 3.

Growth Conditions
Grow cells in culture vessels* pre-coated with 50 ?g/ml poly-L-ornithine (PLO) (TM062) and 1 ?g/ml fibronectin (EMD Millipore; Cat. FC010) in H?O for at least 3 hours at 37?.?fter 3-hour incubation, aspirate the coating solution, rinse vessel with sterile H?O, and use the vessel right away.*Do not grow cells in culture vessels with surface areas equal to or less than 12.5 cm? cells do not grow in 6-well, 24-well, 48-well, or 96-well plates.

Notes
1. Visually examine the packaging containers for signs of leakage or breakage. 2. Immediately transfer frozen cells from dry ice packaging to a temperature below -130?, preferably in liquid nitrogen vapor phase storage, until ready for use.To ensure the highest level of viability, thaw the vial and initiate culture as soon as possible upon receipt. If continued storage is desired, the vial should only be stored below -130? or in liquid nitrogen vapor phase. Do not store at -70?, as it will result in loss of viability.

Propagation
Use of PriCoatTMT25 Flasks (G299) or Applied Cell Extracellular Matrix (G422) is required for cell adhesion to the culture vessels. Grow cells inECM-coated culture vessels unless otherwise specified in the Propagation Requirements below.The base medium for this cell line is Prigrow IV medium available at abm, Cat. No. TM004. To make the complete growth medium, add the following components to the base medium: fetal bovine serum (TM999)* to a final concentration of 15%, L-glutamine (G275) to a final concentration of 1% and Penicillin/Streptomycin Solution (G255) to a final concentration of 1%.Change media every 2-3 days.Carbon dioxide (CO2): 5%, Temperature: 37.0°C.* Do not use heat-inactivated FBS for cell culture unless specified otherwise.

Thawing Protocol
1. Thaw cells quickly in a 37? water bath while agitating gently (maximum 2 minutes). The vial cap should be kept above the water level to minimize the risk of contamination. 2. Decontaminate the vial by spraying and wiping the exterior of the vial with 70% ethanol. From this point onwards, all operations should be strictly carried out inside a biological safety cabinet using aseptic conditions. 3. Transfer the cell suspension into a 15ml sterile conical tube containing 5ml of pre-warmed, complete growth media supplemented with 10% FBS. Centrifuge cells at 125xg for 5 minutes. 4. Aspirate the supernatant without disturbing the cell pellet. Re-suspend the cell pellet in the recommended pre-warmed, complete growth media and dispense into a T25 culture flask. 5. Incubate the cells at the recommended conditions. 6. Cells take 4-5 days to recover and attach. Do not change media during this time. Add additional fresh growth media as needed.?.?Perform media changes regularly; do not let media change colour to orange-yellow.
Subculture Protocol
Volumes given below are for a T75 flask; proportionally increase or decrease the volume as required per culture vessel size. Subculture cells once the culture vessel is 50-60% confluent.?. Aspirate the culture media, and add 2-3ml of pre-warmed 0.25% Trypsin-EDTA to the culture vessel. 2. Observe the cells under a microscope to confirm detachment (typically within 2-10 minutes). Cells that are difficult to detach can be put in 37?, for several minutes to facilitate detachment. 3. Neutralize Trypsin-EDTA by adding an equal volume of the complete growth media into the culture vessel. 4. Transfer the culture suspension into a sterile centrifuge tube, and centrifuge at 125xg for 5 minutes. The actual centrifuge duration and speed may vary depending on the cell type. 5. Aspirate the supernatant, and re-suspend the pellet with pre-warmed fresh complete growth media. Add appropriate aliquots of the cell suspension to new culture vessels, as desired. 6. Incubate the cells at the recommended conditions.
