Descrição	The HK Mad2-LAP/H2B-mCherry cell line is a genetically engineered cell model extensively utilized for studying chromosome segregation and the spindle assembly checkpoint during mitosis. These cells are derived from HeLa Kyoto cells, a robust human cell line originally taken from a cervical carcinoma. The HK Mad2-LAP (LAP-tagged Mad2) aspect of the cell line facilitates the visualization and functional analysis of the Mad2 protein, a critical component of the spindle assembly checkpoint that prevents anaphase onset until all chromosomes are properly aligned at the metaphase plate. Incorporation of H2B-mCherry, where histone H2B is tagged with the mCherry fluorescent protein, allows for real-time imaging of chromatin dynamics during cell division. This feature makes the HK Mad2-LAP/H2B-mCherry cell line an excellent tool for high-resolution live-cell imaging techniques to observe chromosomal movements and mitotic progression in human cells under various experimental conditions. The use of fluorescent tags aids in precise tracking and quantification, thereby providing valuable insights into the molecular mechanisms governing cell cycle regulation and chromosomal stability.

Expressão de proteínas	Mad2-LAP/H2B-mCherry

Meio de cultura	DMEM, w: 4.5 g/L Glucose, w: 4 mM L-Glutamine, w: 3.7 g/L NaHCO3, w: 1.0 mM Sodium pyruvate (Cytion article number 820300a)
Suplementos	Supplement the medium with 10% FBS
Reagente de dissociação	Accutase
Subcultura	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.
Densidade de semeadura	1 x 10⁴ cells/cm²
Renovação de fluidos	2 to 3 times per week
Recuperação pós-degelo	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.
Meio de congelamento	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.
Descongelamento e cultura de células	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.
Atmosfera de incubação	37°C, 5% CO₂, humidified atmosphere.
Condições de envio	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.
Condições de armazenamento	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.

Esterilidade	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.
