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

Notes

Although we aim to provide customers with a homozygous clone, feasibility will be dependent on the biology of the protein. Should only heterozygous edits be achieved, you will be notified of the outcome and be asked to confirm whether the cell line is acceptable. All clones will be accompanied with DNA sequencing data, and the mutation description.

Recommended control: Human wild-type A549 cell line (ab288558). 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

The proteasome LMP2 also known as proteasome subunit beta type-1 or PSMB9 is a component important in the functioning of the 20S proteasome complex. This molecular entity with a mass of approximately 23 kDa is predominantly expressed in immune cells including lymphocytes. LMP2 incorporates into the immunoproteasome a specialized variant of the proteasome that participates prominently in the processing of class I MHC peptides enhancing the immune response.

Biological function summary

LMP2 is integral to protein catabolism and regulation of the cellular protein homeostasis. As part of the larger proteasome complex the LMP2 protein functions in degradative pathways that recycle amino acids from ubiquitin-tagged proteins. This proteasome takes part in antigen processing helping convert proteins into peptides that are presented on the surface of cells for immune system recognition.

Pathways

LMP2 is significantly involved in the ubiquitin-proteasome pathway and immune system processes. It interacts with other immunoproteasome subunits like LMP7 and MECL-1 which work together to enhance the proteolytic capacity for antigen presentation. The presence of LMP2 in these pathways demonstrates its role in adaptive immunity contributing to the clearance of misfolded or damaged proteins and therefore maintaining cell health.

Associated diseases and disorders

LMP2 associates with immune-related conditions and some cancer types. Dysregulation of LMP2 expression or function can impact antigen presentation potentially leading to autoimmune disorders due to inappropriate immune activation. Moreover alterations in LMP2 expression have been observed in certain cancers such as melanoma where it affects proteasome activity and influences tumor progression. In these contexts interactions with proteins like TAP1 and TAP2 which aid in peptide transport mark its relevance in disease pathogenesis.
