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.
- Cryopreservation medium
- Cell Freezing Medium-DMSO Serum free media, contains 8.7% DMSO in MEM supplemented with methyl cellulose.

Notes
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.

- Activity summary
Asparagine synthetase (ASNS) is an enzyme that catalyzes the conversion of aspartate and glutamine to asparagine and glutamate. This enzyme is also known by the alternate name ASPG. Asparagine synthetase weighs approximately 64 kDa and it is found in many tissues including the liver and pancreas. The presence of ASNS is important for the synthesis of asparagine an amino acid necessary for protein and nucleotide synthesis.
- Biological function summary
ASNS drives the synthesis of asparagine through a mechanism involving the ATP-dependent conversion of substrates. It does not function as part of a larger enzyme complex but operates independently to fulfill its role. In cells asparagine produced serves as a critical building block supporting protein biosynthesis and cell proliferation particularly in rapidly dividing cells such as cancer cells.
- Pathways
Asparagine synthetase plays a central role in the asparagine biosynthetic pathway. This enzyme is key for maintaining cellular amino acid homeostasis and is linked to the mTOR pathway which regulates cell growth and metabolism. Additionally ASNS interacts with proteins like glutaminase which supplies one of its essential substrates glutamine.
- Associated diseases and disorders
ASNS has a significant correlation with acute lymphoblastic leukemia (ALL) where asparagine levels affect cancer cell survival. Targeting ASNS can influence chemotherapeutic strategies given its role in providing asparagine to leukemic cells. Additionally ASNS deficiency can lead to severe neurological conditions further highlighting its importance in human health. Its interaction with glutaminase is particularly relevant as both are involved in pathways targeted in ALL treatments.
