Immortalized Rat Myoblast-like Tertracycline Cell Line (RMT 6211) is derived from rat skeletal muscle and have been immortalized via transfection with the NIT-Tag retrovirus, containing a temperature sensitive mutant of the SV40 large T Antigen. This cell line was developed in order to provide a source of myofibers that could exhibit contractile activity similar to that seen in primary muscle cultures. Follwing differentiation, the RMT 6211 cell line was found to express markers for Pax7, MyoD, Myf-5, MRF4, and Myogenin. As a result, this immortalized cell line is a useful alternative to primary cultures and can be used to study muscle differentiation, as well as molecular and physiological aspects of electrical activity in muscle fibres.

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
Cultures can be grown on poly(2-hydroxyethylmethacrylate) (PHEMA, #P3932; Sigma) coated cell culture vessels to prevent cell attachment.The base medium for this cell line is Neurobasal medium containing 2 mM L-glutamine, 2% B27 supplement (Thermo Fisher Scientific, Waltham, CA, USA), 10 ng/mL of FGF2 (Z101455), 10 ng/mL of EGF (Z100135), 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.To differentiate into neuronal and glial cells:Dissociated cells were seeded, 1-2 x 104 cells per well on poly-L-lysine (PLL)-coated 6 cm dishes. Maintain the cells in differentiation media: F12 medium (Thermo Fisher) supplemented with fetal bovine serum (TM999)* to a final concentration of 5%, 0.5% N2 supplement (Thermo Fisher), 1% B27 supplement,1 muM all-trans retinoic acid (ATRA; Sigma), 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. Centrifuge cells at 125xg for 5-7 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.
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 80% confluent. 1. 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.
