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.

Biological function summary
The protein NRG4 plays a significant role in regulating energy metabolism and maintaining homeostasis. It is not part of a complex but as a ligand it interacts directly with its receptor ErbB4. NRG4 activity helps regulate liver lipid metabolism preventing excessive lipid accumulation. Furthermore NRG4 involvement extends to pancreatic function where it aids in preserving insulin sensitivity with implications for glucose homeostasis.
Pathways
The protein NRG4 acts within the ErbB signaling pathway which is critical for cellular growth and differentiation. In this pathway NRG4 enhances the proliferation and differentiation of cells by activating the ErbB4 receptor. NRG4 also interfaces with the PI3K/AKT pathway playing a role in metabolic processes and cellular survival. The interaction with ErbB4 signifies its relation to other neuregulin proteins like NRG1 which also engage this receptor family showcasing their coordinated impact on metabolic regulation.
