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

Activity summary

The SA2 protein also known as stromal antigen 2 is a component of the cohesin complex playing a significant role in chromosomal dynamics. With an approximate molecular weight of 152 kDa SA2 exhibits high expression in the nucleus of proliferating cells particularly during interphase. This cohesin component contributes critically to maintaining sister chromatid cohesion and ensuring proper segregation during cell division serving as a functional partner in the cohesin complex with other components like SMC1 SMC3 and RAD21.

Biological function summary

SA2 plays an important role in regulating gene expression by forming loops that connect different genomic regions. SA2 as a member of the cohesin complex also participates in DNA repair by facilitating accurate recombination enhancing genome stability. This involvement is essential for maintaining chromatin structure which influences diverse cellular processes. Its expression can be an important modulator in the dynamic environment of cellular proliferation and differentiation.

Pathways

SA2 functions integrally within the cohesin-mediated sister chromatid cohesion pathway and the DNA damage response pathway. In these pathways SA2 teams with proteins such as CTCF in insulator function regulation and BRCA1 in DNA repair mechanisms. The cohesin-SA2 interaction with these proteins ensures proper chromosomal architecture and integrity which are essential for the accurate transmission of genetic material across generations of cells.

Associated diseases and disorders

SA2 mutations or dysregulations have been linked to Cornelia de Lange Syndrome (CdLS) and certain cancers. In CdLS SA2 mutations disrupt normal cohesin function affecting developmental processes. In cancer contexts abnormal SA2 function or expression can lead to improper DNA repair contributing to genomic instability and tumorigenesis. It is often studied in concert with other cohesin proteins and regulatory elements like NIPBL which provides insights into cohesin-related pathologies and potential therapeutic targets.
