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

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 HEK293T cell line (ab255449). 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.

• Do not allow the cell density to exceed 7x10E4 cells/cm2.
We will provide viable cells that proliferate on revival.

Supplementary info

- Activity summary
Ephrin A3 also known as Ephrin-A3 or EFNA3 is a member of the ephrin family that interacts with Eph receptors which are a group of tyrosine kinase receptors. Ephrin A3 has a mass of approximately 24 kDa. It is expressed in various tissues including the brain where it plays a significant role in neural development. The expression pattern of Ephrin A3 suggests its involvement in a wide range of physiological processes.
- Biological function summary
Ephrin A3 acts as an important regulator in cell communication and spatial organization within the brain's neuronal network. It forms a complex with Eph receptors on adjacent cells leading to bidirectional signaling necessary for processes like axon guidance and synaptic plasticity. Ephrin A3's ability to guide axons is important for neural pathfinding during development. It also participates in the clustering of neurons required for the formation of precise neural circuits.
- Pathways
Ephrin A3 is a significant player in the Eph/ephrin signaling pathway which influences the dynamics of cell adhesion shape and movement. It is closely related to EphA3 and EphA4 receptors through these pathways. The signaling influences the cytoskeleton affecting cell migration and tissue boundary formation. Additionally Ephrin A3 interacts within the Rho family of GTPase signaling pathways that regulate cytoskeletal rearrangements impacting cellular morphology and motility.
- Associated diseases and disorders
Ephrin A3 is implicated in conditions like cancer and neurological disorders. Aberrant expression or signaling of Ephrin A3 contributes to tumor progression and metastasis potentially through its role in modifying cell adhesion and migration. Through its involvement in the neural network it may also relate to neurodegenerative diseases. The interaction with proteins like EphA2 in cancer highlights its potential as a therapeutic target. Understanding these interactions opens pathways for strategies to modulate its function in disease contexts.
