This novel, immortalized ecrine sweat gland myoepithelial cell line (iEM) serves as a model for research on sweat glands and sweating. These cells were developed from primary cells transduced with lentiviral vectors containing hTERT and SV40T. Cells display spheroid formation with increased population doubling compard to non-transduced cells. iEM's express myoepithelial cell-specific proteins (a-SMA, B1 or K14) and can differentiate into luminal cells. Immortalized Sweat Gland Myoepithelial Cells provide a useful?n vitro?odel for recapitulating eccrine sweat gland functions and for screening substances that can modulate sweating by acting on sweat glands. These cells are applicable for studies in hyperhidrosis, adiaphoresis, and sweat gland diseases. Please note: cells are exected to grow to 65 population doublings (PDs), however, the exact PD limit can vary by lot.

Disclaimer
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. All of abm's cell biology products are for research use ONLY and NOT for therapeutic/diagnostic applications. abm is not liable for any repercussions arising from the use of its cell biology product(s) in therapeutic/diagnostic application(s).

Tissue
Sweat Gland
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.

Product Use
This product is intended for laboratory research use only. It is not intended for any animal or human therapeutic use, any human or animal consumption, or any diagnostic use.
Storage
Vapor phase of liquid nitrogen, or below -130?.
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 300xg 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.
Subculture Protocol
1. Simply add fresh complete media directly to the culture. Do not allow cell density to exceed 1x10? cells/ml. 2. Alternatively, replace complete growth media by centrifugation and re-suspend the cell pellet in fresh complete media, and add appropriate aliquots of the cell suspension to new culture vessels, as desired. 3. Incubate the cells at the recommended conditions.
