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

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

Supplementary information

LGALS9C also known as Galectin-9c belongs to the galectin family which mediates cell-cell interactions cell-matrix adhesion and apoptotic pathways. This protein has a molecular mass of approximately 36 kDa. You can find it expressed in various tissues with notable presence in immune cells suggesting a role in immune system regulation. Researchers often associate other names such as Gal-9S and Galectin-9c Isoform with this protein indicating its various isoforms adapt functions in different cells.
Biological function summary

LGALS9C influences immune response modulation highlighting its presence in immune cell function. It interacts with biologically significant partners often forming a complex with receptors like Tim-3 on T cells. This interaction can either promote cell death in certain contexts or drive anti-inflammatory responses. The involvement of LGALS9C in regulating the survival and function of these cells underlines its importance in maintaining homeostasis within the immune system.

Pathways

LGALS9C plays significant roles within immune signaling pathways including the Tim-3/Galectin-9 pathway. It also intersects with the apoptosis regulatory pathway influencing cellular outcomes during immune responses. LGALS9C interacts with proteins such as Tim-3 and PD-1 which share pathways that regulate immune responses and tolerance. The modulation of immune checkpoints places LGALS9C within a network of pathways that could influence therapy in chronic inflammation and cancer.

LGALS9C shows relevance to autoimmune diseases and cancer. It has been observed to dysregulate inflammatory responses contributing to conditions like systemic lupus erythematosus (SLE). During cancer progression LGALS9C can affect tumor microenvironment by interacting with proteins such as Tim-3 and influencing immune evasion mechanisms. These connections make LGALS9C a target of interest for therapeutic interventions aiming to modulate immune responses in disease treatment.
