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.

Notes

Recommended control: Human wild-type A549 cell line (ab255450). 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

IFI44 also known as Interferon-Induced Protein 44 is a protein encoded by the IFI44 gene. This protein has a molecular mass of approximately 49 kDa. IFI44 expresses in various tissues with elevated levels observed in immune-related cells such as leukocytes. Mechanically IFI44 is known to play a role in the antiviral defense mechanisms of cells often upregulated in response to interferon stimuli. It interacts with cytoskeleton elements to mediate its cellular functions.

Biological function summary

IFI44 participates in cellular defense against viral infections by enhancing the immune response. This protein does not function independently but forms part of interferon-stimulated gene complex working together with other proteins to combat virus replication. By regulating this complex IFI44 influences cell signaling and modulates antiviral pathways contributing to the suppression of viral propagation within host cells.

Pathways

IFI44 functions prominently within the interferon signaling pathway and the innate immune response pathway. It collaborates closely with other interferon-stimulated proteins such as ISG15 and MX1 which are engaged in the virus suppression. This cooperation helps orchestrate a swift immune response to external pathogenic threats by inhibiting viral gene expression and replication processes.

Associated diseases and disorders

IFI44 plays an important role in conditions associated with viral infections such as Hepatitis C and influenza. The protein’s interaction with viral defense proteins like ISG15 is significant in these disorders. Its expression levels often correlate with the severity of the disease serving as a biomarker for the infection state. Understanding IFI44’s precise role in these diseases could lead to novel therapeutic approaches and better management of viral infections.
