Species Canine
The MDCK-SIAT1 cell line is a modified version of the Madin-Darby Canine Kidney (MDCK) cells, engineered to express higher levels of human 2,6-sialyltransferase (SIAT1). This enzyme is responsible for the addition of sialic acid in an alpha-2,6 linkage to galactose on glycoproteins and glycolipids. The modification was performed to increase the expression of alpha-2,6-linked sialic acids, which are the primary receptors for human influenza viruses. This enhancement is critical as it makes the MDCK-SIAT1 cells more similar to the human airway epithelium, which naturally has a high concentration of these receptors. As a result, these cells offer a more physiologically relevant model for studying human influenza viruses and their interactions with potential antiviral compounds. One of the significant applications of MDCK-SIAT1 cells is in the assessment of influenza virus sensitivity to neuraminidase inhibitors (NAIs), such as oseltamivir. Due to the increased presence of alpha-2,6-linked sialic acids, the MDCK-SIAT1 cells demonstrate improved sensitivity to NAIs compared to unmodified MDCK cells. This makes them an excellent tool for detecting resistance to these inhibitors, especially in low-passage-number clinical isolates of human influenza viruses. The MDCK-SIAT1 cell line allows for more accurate in vitro studies of drug efficacy and viral receptor interactions, providing valuable insights into the development of antiviral therapies and resistance mechanisms.

Protein expression: Transfected with ST6 beta-galactoside alpha-2,6-sialyltransferase 1 (ST6GAL1, SIAT1)

  • 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 and 1mg/ml G418
  • dissociationReagent: Accutase
  • doublingTime: 21 to 31 hours
  • 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: 2 to 4 x 104 cells/cm2
  • fluidRenewal: 2 to 3 times per week
  • 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.
