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.

Supplementary information

SDF4 also known as Stromal Cell Derived Factor 4 or Cab45 is a calcium-binding protein with a molecular mass of approximately 45 kDa. It is expressed in the Golgi apparatus of cells in various tissues including pancreas liver and brain. SDF4 plays a mechanical role in sorting and trafficking of proteins through the secretory pathway specifically during the transport of secretory cargo in the Golgi.
Biological function summary

This protein participates in the regulation of calcium-dependent vesicle transport. It does not function as part of a large protein complex but interacts with different proteins in the Golgi for sorting activities. SDF4's ability to bind calcium allows it to modulate interactions necessary for vesicle movement and cargo recognition affecting how proteins exit the Golgi and are distributed to other areas of the cell.

Pathways

Studies show SDF4 is involved in the cellular secretory pathway and calcium signaling pathway. Within these pathways SDF4 interacts with proteins like co-chaperone SIL1 to ensure proper protein folding and trafficking. SDF4 also contributes to vesicle budding processes that are essential for maintaining proper cellular function and homeostasis.

Dysfunction of SDF4 links to disorders such as diabetes and neurodegenerative diseases. Abnormal SDF4 expression impacts proteins like insulin in the pancreatic pathway contributing to diabetes through misfolding or improper secretion of insulin. In neurodegenerative conditions SDF4's disrupted association with proteins involved in calcium homeostasis affects synaptic function and neuron health implicating it in diseases like Alzheimer's.
