1x10⁶ cells / 1.0 ml
| Cat. No. | T0532 |
| Name | Immortalized Human Trophoblast Cells - hTERT (Sw.71) |
| Description |
The Immortalized Human Trophoblast Cells - hTERT (Sw.71) were derived from 7-week first trimester placenta isolated from normal pregnancy and were virally infected with hTERT. The immortalized cells retained the same morphology as their primary counterparts. It has the abilities to spontaneously fuse as occasional multi-nucleated cells clusters may form, and can secrete cytokines (IL-1β, IL-6, IL-8, Monocyte Chemotactic Protein-1 (MCP-1), GRO (CXCR2), GRO-α (CXCL1), Intercellular Adhesion Molecule-1 (ICAM-1), Osteoprotegerin (OPG), Tissue Inhibitor of Metalloproteinase-1 (TIMP-1), TIMP-2 and VEGF). Cytokeratin 7 and vimentin markers are expressed. The population of cells is determined to be free of immune cells due to the absence of CD45 and CD68, and free of fibroblast cells due to the lack of fibroblast specific antigen. The Sw.71 cells are a valuable tool for trophoblast research. |

| Intended 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. |
| BioSafety | II |
| Certificate of Analysis | For batch-specific test results, refer to the applicable certificate of analysis that can be found at www.abmgood.com. |
| Growth Conditions |
PriCoat™ T25 Flasks (G299) or Applied Cell Extracellular Matrix (G422) are recommended for optimal cell culture. PriGrow IV (TM004) + 10% FBS + 1 mM Sodium Pyruvate (TM057) + 2 mM L-glutamine (G275) + 10 mM HEPES (TM058) + 1X Non-Essential Amino Acids (TM068) + 1% Penicillin/Streptomycin Solution (G255), 37.0°C, 5% CO₂. |
| Unpacking and Storage Instructions |
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°C, 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°C or in liquid nitrogen vapor phase. Do not store at -70°C, as it will result in loss of viability. |
| Thawing Protocol |
1. Thaw cells quickly in a 37°C 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°C, 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. |
