Species Human
The HK EGFP-LaminB1/H2B-mCherry cell line is an Hela Kyoto derived in vitro model designed for real-time visualization of chromatin dynamics and nuclear architecture in living cells. This cell line expresses two fluorescent protein fusions: EGFP (enhanced green fluorescent protein) fused with Lamin B1, and mCherry (a red fluorescent protein) fused with histone H2B. The fusion of EGFP with Lamin B1 allows for the observation of the nuclear envelope and nuclear lamina, structures critical for maintaining the integrity and functionality of the nucleus. Lamin proteins are type V intermediate filament proteins that form a meshwork underlying the inner nuclear membrane, playing key roles in nuclear stability, chromatin organization, and gene regulation. On the other hand, the mCherry-tagged histone H2B enables the visualization of chromatin within the nucleus. Histones are fundamental components of the nucleosome, involved in the organization of DNA into chromatin, making them crucial for DNA replication, repair, and transcription. The mCherry tag on H2B provides a vivid red fluorescence that contrasts with the green fluorescence of EGFP, allowing for simultaneous dual-imaging of the nuclear structure and chromatin in live-cell experiments. This cell line is commonly used in studies focusing on nuclear mechanics, mitosis, and genome stability, providing a dynamic view of cellular processes that are otherwise difficult to observe in real time.

  • Protein expression: EGFP-LaminB1/H2B-mCherry
  • Products: Histone H2B
  • cultureMedium: 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)
  • supplements: Supplement the medium with 10% FBS
  • dissociationReagent: Accutase
  • subculturing: 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.
  • seedingDensity: 1 x 104 cells/cm2
  • fluidRenewal: 2 to 3 times per week
  • postThawRecovery: 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.
  • freezeMedium: As a cryopreservation medium, 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.
