Product details

Although we aim to provide customers with a homozygous clone, feasibility will be dependent on the biology of the protein. Should only heterozygous edits be achieved, you will be notified of the outcome and be asked to confirm whether the cell line is acceptable. All clones will be accompanied with DNA sequencing data, and the mutation description.

Recommended control: Human wild-type A549 cell line (ab288558). Please note a wild-type cell line is not automatically included with a knockout cell line order, if required please add recommended wild-type cell line at no additional cost using the code WILDTYPE-TMTK1.

We will provide viable cells that proliferate on revival.

This product is subject to limited use licenses from The Broad Institute and ERS Genomics Limited, and is developed with patented technology. For full details of the limited use licenses and relevant patents please refer to our limited use license and patent pages.

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.
  • Do not allow the cell density to exceed 7x104 cells/cm2.
Culture medium

F-12K + 10% FBS

Cryopreservation medium

Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

The protein 'Hamartin' also known as TSC1 plays a mechanical role in cellular processes primarily as a regulator of cellular growth and proliferation. It interacts with Tuberin (TSC2) to form a complex that inhibits the small GTPase Rheb thereby controlling the mTOR signaling pathway. Hamartin has a molecular mass of approximately 130 kDa. It is expressed in various tissues including the brain heart and kidneys highlighting its significance in multiple physiological processes.
Biological function summary

Hamartin functions as part of the TSC1-TSC2 complex which acts as a tumor suppressor. This complex inhibits the mechanistic target of rapamycin complex 1 (mTORC1) an essential regulator of cell growth proliferation and protein synthesis. Through this regulation Hamartin plays a critical role in maintaining cellular homeostasis and preventing abnormal cell growth that can lead to tumorigenesis.

Pathways

Hamartin is integral to the mTOR signaling pathway an important pathway that regulates cell metabolism growth and survival. This pathway involves the interaction of Hamartin with Tuberin (TSC2) helping to control the activation of mTORC1. Additionally Hamartin is involved in the PI3K/Akt signaling pathway which further influences mTOR activity and cellular responses to growth factors.

Disruptions in Hamartin function are linked to Tuberous Sclerosis Complex (TSC) a genetic disorder characterized by tumor development in multiple organs. Mutations in the TSC1 gene lead to the loss of Hamartin function resulting in uncontrolled cell growth. Additionally research indicates that Hamartin may have a connection to certain epilepsy types given its expression in the brain and its role in neuronal development. In these conditions the interaction of Hamartin with Tuberin is essential for regulating cellular behavior and preventing disease progression.
