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.

Activity summary

Claudin 1 also known as CLDN1 is a protein that plays a fundamental role in the formation of tight junctions in the epithelial cells. This claudin protein has a molecular weight of approximately 22 kDa. You can find it expressed in various tissues including the skin liver kidney and lungs. Claudin 1 belongs to the claudin family which consists of transmembrane proteins involved in sealing the space between adjacent cells therefore ensuring tissue integrity.

Biological function summary

This claudin protein contributes to establishing and maintaining the barrier function that controls paracellular transport which is the movement of substances between cells. Claudin 1 participates as a critical component of the tight junction complex and it interacts with other proteins such as occludin and zonula occludens. These interactions contribute to the regulation and maintenance of cell polarity and signaling.

Pathways

Claudin 1 is involved in the epithelial cell signaling pathways that influence cellular proliferation and differentiation. One significant pathway is the Wnt signaling pathway where claudin 1 cooperates with other claudins and proteins like β-catenin to regulate gene transcription. Additionally it is implicated in the MAPK pathway which involves signaling cascades that affect cell growth division and response to external stress.

Associated diseases and disorders

Claudin 1 shows a strong association with cancers particularly hepatocellular carcinoma and melanoma. In these conditions changes in claudin 1 expression levels can affect tumor progression and metastasis. It also associates with other proteins like E-cadherin impacting cell adhesion and epithelial-mesenchymal transition in cancerous cells. Moreover abnormalities in claudin 1 expression relate to skin disorders such as ichthyosis which is marked by a dysfunction in the skin barrier.
