Western blot - Human TAP2 knockout HeLa cell line (AB265426)
False colour image of Western blot : Anti-TAP2 antibody staining at 1/500 dilution, shown in green; Mouse anti-GAPDH antibody [6C5] (ab8245) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab180611 was shown to bind specifically to TAP2. A band was observed at 75 kDa in wild-type HeLa cell lysates with no signal observed at this size in Tap2 knockout cell line ab265426 (knockout cell lysate ab258712). To generate this image, wild-type and Tap2 knockout HeLa cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (ab216776) at 1/20000 dilution.

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.

Biological function summary
The TAP2 protein operates as an important component of the immune system by facilitating the processing and presentation of antigens. It partners with TAP1 and forms a heterodimer complex essential for the transportation of peptides that are 8-16 amino acids long. This action is fundamental for the proper presentation of antigens on major histocompatibility complex (MHC) class I molecules which are pivotal in the recognition of infected or abnormal cells by cytotoxic T lymphocytes.
Pathways
The TAP2 protein plays a significant role in the antigen processing and presentation pathways. It directly impacts the MHC class I pathway by aiding in the selection and transport of peptides that bind to MHC class I molecules. TAP2 functions alongside related proteins such as TAP1 and tapasin which help facilitate the loading of these peptides onto MHC class I molecules in the endoplasmic reticulum preparing them for cell surface presentation.
