Handling procedures
- Initial handling guidelines
Upon arrival, the vial should be stored in liquid nitrogen vapor phase and not at -80°C. Storage at -80°C may result in loss of viability.
1. Thaw the vial in 37°C water bath for approximately 1-2 minutes.
2. Transfer the cell suspension (0.8 mL) to a 15 mL/50 mL conical sterile polypropylene centrifuge tube containing 8.4 mL pre-warmed culture medium, wash vial with an additional 0.8 mL culture medium (total volume 10 mL) to collect remaining cells, and centrifuge at 201 x g (rcf) for 5 minutes at room temperature. 10 mL represents minimum recommended dilution. 20 mL represents maximum recommended dilution.
3. Resuspend the cell pellet in 5 mL pre-warmed culture medium and count using a haemocytometer or alternative cell counting method seed all remaining cells into a T25.
4. Incubate the culture at 37°C incubator with 5% CO2. Check the culture one day after revival and continue to check until 80% confluent. Media change can be given if needed.
5. Once confluent passage into an appropriate flask at a density of 2x104 cells/cm2. Seeding density is given as a guide only and should be scaled to align with individual lab schedules. Cultures should be monitored daily.- Subculture guidelines
- All seeding densities should be based on cell counts gained by established methods.
- A guide seeding density of 2x104 cells/cm2 is recommended.
- Cells should be passaged when they have achieved 80-90% confluence.
- Culture medium
- DMEM (High Glucose) + 10% FBS
- Cryopreservation medium
- Cell Freezing Medium-DMSO Serum free media, contains 8.7% DMSO in MEM supplemented with methyl cellulose.
Storage
- Shipped at conditions
- Dry Ice

Supplementary info
- This supplementary information is collated from multiple sources and compiled automatically.
- Activity summary
Transducin-Like Enhancer of Split 1 also known as TLE1 is a transcriptional corepressor well-known for its involvement in Notch and Wnt signaling pathways. TLE1 has a molecular mass of approximately 77 kDa. This protein is expressed in various tissues including the brain heart and lung highlighting its involvement in multiple biological systems. Researchers recognize its importance in modulating gene expression through interactions with different transcription factors.
- Biological function summary
The TLE1 protein plays a role in embryonic development by regulating the transcription of genes critical for cell differentiation. TLE1 forms part of a complex with other proteins to exert its corepressive function effectively. Through these interactions TLE1 is involved in differentiation processes in cells such as MCF-7 a breast cancer cell line influencing cellular behavior and function.
- Pathways
TLE1 influences the Notch and Wnt signaling pathways essential for cell fate determination and proliferation. Its interaction with key proteins like β-catenin and Notch receptor proteins connects it to these pathways modulating the transcription of target genes. TLE1's role in these pathways is important for maintaining balanced cellular processes and preventing abnormal cell growth.
- Associated diseases and disorders
TLE1 is linked to various forms of cancer including synovial sarcoma and breast cancer. Its overexpression has been observed in these cancers often in conjunction with other proteins like BCL2 supporting cell survival and resisting apoptosis. TLE1's involvement in these diseases makes it a target for therapeutic strategies aimed at modulating its activity to inhibit tumor progression.

Anti-TLE 1 antibody [EPR9386(2)] ab183742 Anti-TLE 1 antibody [EPR9386(2)] was shown to specifically react with TLE 1 in wild-type HEK293T cells. Loss of signal was observed when knockout cell line ab265059 (knockout cell lysate Human TLE1 knockout HEK-293T cell lysate ab257240) was used. Wild-type and TLE 1 knockout samples were subjected to SDS-PAGE. Anti-TLE 1 antibody [EPR9386(2)] ab183742 and Anti-GAPDH antibody [6C5] - Loading Control (Anti-GAPDH antibody [6C5] - Loading Control ab8245) were incubated overnight at 4°C at 1 in 1000 dilution and 1 in 20000 dilution respectively.
