說明	HEK 293T, a highly transfectable derivative of the parental HEK 293 cell, stands out as a versatile and powerful tool in the field of biotechnology for the production of recombinant proteins and various types of vaccines. HEK-293T cells were generated by transfecting embryonic kidney 293 cells with a plasmid encoding the SV40 large T antigen. The original HEK293 cell line was developed from the epithelial cells of human embryonic kidney tissue, with its transformation occurring in what was notably the 293rd experiment conducted by the researchers. In the realm of vaccine development, the 293T embryonic kidney cells are pivotal for viral vector production, including adenovirus vectors. HEK293T cells, under specific culture conditions, are transfected with vectors carrying adenoviral and retroviral elements, including the SV40 origin of replication, leading to the production of virus-like particles (VLPs). The VLPs, devoid of viral genetic material, are key in forming the basis of subunit and VLP-based vaccines. The recombinant protein production in 293T cells is facilitated by various transfection methods, with an emphasis on the generation of AP fusion proteins and other protein types that form the antigenic component of vaccines. The 293T cell line's genome engineering capabilities allow for the customization of expression constructs, further boosting the production of viral vectors. This, coupled with the ability to produce proteins in suspension culture or adherent conditions, makes the 293T cell line a full-stack solution for modern vaccine development.

受體的表達	Vitronectin
蛋白質表達	CEA negative, p53 positive
致瘤性	In nude mice

培養基	EMEM (MEM Eagle), w: 2 mM L-Glutamine, w: 2.2 g/L NaHCO3, w: EBSS (Cytion article number 820100a)
營養補充品	Supplement the medium with 10% FBS and 1% NEAA
解離試劑	Accutase
倍增時間	30 hours
傳代培養	Remove the old medium from the adherent cells and wash them with PBS that lacks calcium and magnesium. For T25 flasks, use 3-5 ml of PBS, and for T75 flasks, use 5-10 ml. Then, cover the cells completely with Accutase, using 1-2 ml for T25 flasks and 2.5 ml for T75 flasks. Let the cells incubate at room temperature for 8-10 minutes to detach them. After incubation, gently mix the cells with 10 ml of medium to resuspend them, then centrifuge at 300xg for 3 minutes. Discard the supernatant, resuspend the cells in fresh medium, and transfer them into new flasks that already contain fresh medium.
播種密度	1 x 10⁴ cells/cm² will yield in a confluent layer in about 4 days
流體更新	2 times per week
解凍後的恢復	After thawing, plate the cells at 5 x 10⁴ cells/cm² and allow the cells to recover from the freezing process and to adhere for at least 24 hours.
冷凍培養基	As a cryopreservation medium, we use complete growth medium (including FBS) + 10% DMSO for adequate post-thaw viability, or CM-1 (Cytion catalog number 800100), which includes optimized osmoprotectants and metabolic stabilizers to enhance recovery and reduce cryo-induced stress.
細胞解凍與培養	Confirm that the vial remains deeply frozen upon delivery, as cells are shipped on dry ice to maintain optimal temperatures during transit. Upon receipt, either store the cryovial immediately at temperatures below -150°C to ensure the preservation of cellular integrity, or proceed to step 3 if immediate culturing is required. For immediate culturing, swiftly thaw the vial by immersing it in a 37°C water bath with clean water and an antimicrobial agent, agitating gently for 40-60 seconds until a small ice clump remains. Perform all subsequent steps under sterile conditions in a flow hood, disinfecting the cryovial with 70% ethanol before opening. Carefully open the disinfected vial and transfer the cell suspension into a 15 ml centrifuge tube containing 8 ml of room-temperature culture medium, mixing gently. Centrifuge the mixture at 300 x g for 3 minutes to separate the cells and carefully discard the supernatant containing residual freezing medium. Gently resuspend the cell pellet in 10 ml of fresh culture medium. For adherent cells, divide the suspension between two T25 culture flasks; for suspension cultures, transfer all the medium into one T25 flask to promote effective cell interaction and growth. Adhere to established subculture protocols for continued growth and maintenance of the cell line, ensuring reliable experimental outcomes.
培養環境	37°C, 5% CO₂, humidified atmosphere.
運送條款	Cryopreserved cell lines are shipped on dry ice in validated, insulated packaging with sufficient refrigerant to maintain approximately −78 °C throughout transit. On receipt, inspect the container immediately and transfer vials without delay to appropriate storage.
儲存條件	For long-term preservation, place vials in vapor-phase liquid nitrogen at about −150 to −196 °C. Storage at −80 °C is acceptable only as a short interim step before transfer to liquid nitrogen.

不孕症	Mycoplasma contamination is excluded using both PCR-based assays and luminescence-based mycoplasma detection methods. To ensure there is no bacterial, fungal, or yeast contamination, cell cultures are subjected to daily visual inspections.
