AP2B1 KO cell line available to order. KO validated by Western blot. Free of charge wild type control provided. Knockout achieved by using CRISPR/Cas9, Homozygous: 1 bp insertion in exon 3.
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.
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 HEK293T cell line (ab255449). 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.
Cryopreservation cell medium: Cell Freezing Medium-DMSO Serum free media, contains 8.7% DMSO in MEM supplemented with methyl cellulose.
Culture medium: DMEM (High Glucose) + 10% FBS

Subculture guidelines:
• All seeding densities should be based on cell counts gained by established methods.
• A guide seeding density of 2x10E4 cells/cm2 is recommended.
• Cells should be passaged when they have achieved 80-90% confluence.
• Do not allow the cell density to exceed 7x10E4 cells/cm2.
We will provide viable cells that proliferate on revival.

AP2B1 also known as the beta-1 subunit of the adaptor protein complex 2 (AP-2 complex) has a mass of approximately 105 kDa. It plays an important role in clathrin-mediated endocytosis by forming a bridge between clathrin and cargo molecules. The AP-2 complex is essential for selecting and concentrating cargo proteins that are destined for endocytosis. AP2B1 is highly expressed in most tissues with abundant presence in brain tissue suggesting its importance in neural processes.
AP2B1 functions as a component of the AP-2 complex which is essential for the formation of clathrin-coated pits on the plasma membrane. It contributes to the regulation of receptor-mediated endocytosis a process important for nutrient uptake and signaling receptor regulation. The AP-2 complex binds to the cytoplasmic tails of transmembrane proteins mediating their internalization into cells for degradation or recycling. This highlights AP2B1's role in maintaining cellular homeostasis and responding to environmental signals.
Researchers have shown that AP2B1 is actively involved in the endocytic pathway facilitating the internalization of cell surface receptors into vesicles. It is also linked to the sorting of cargo proteins within the endocytosis pathway in tandem with other proteins like calmodulin. The interaction with dynamin regulates the membrane scission events necessary for vesicle release. Both calmodulin and dynamin are important for the successful execution of these pathways where AP2B1 plays a central role.
Disruptions in AP2B1 function link to neurological disorders such as Alzheimer’s disease potentially due to impaired endocytosis and subsequent cellular signaling dysfunctions. Abnormalities in the AP-2 complex including AP2B1 have also been associated with cancers like melanoma where altered receptor endocytosis can lead to uncontrolled cell signaling and proliferation. Both conditions involve pathways where dynamin works closely with AP2B1 hinting at its wider implications in disease progression and therapeutic target potential.
