MDBK cells, short for Madin-Darby Bovine Kidney cells (also known as NBL-1), are an exceptional biological resource derived from the kidneys of apparently healthy adult Bos taurus, specifically male individuals. These cells grow adherently and possess an epithelial-like morphology. One of the remarkable applications of MDBK cells lies in their ability to facilitate in vitro studies on the expression of Eimeria bovis-derived antigens on the host cell surface membrane. Additionally, MDBK cells have been employed in investigations centred around the ubiquitination and degradation of signal transducer and activator of transcription 1 and 2 (STAT1 and STAT2) by the V proteins of paramyxoviruses, such as simian virus five and human parainfluenza virus type 2. With an average doubling time ranging from 24 to 35 hours, MDBK cells exhibit a moderate proliferation rate. The establishment of the MDBK cell line dates back to February 18, 1957, when S.H. Madin and N.B. Darby successfully derived it from the kidney of a healthy adult steer. Since then, these cells have become a cornerstone in biological research, enabling numerous breakthroughs in various scientific fields. The karyotype analysis of MDBK cells reveals a modal chromosome number of 51, indicating a hypodiploid state. Within the cell population, the hypodiploid condition manifests as a stemline chromosome number of 2n = 60, with a 2S component occurring in approximately 5% of the cells. Moreover, 11-14 marker chromosomes are typically present, comprising a combination of metacentric, submetacentric, and acro-telocentric chromosomes. Notably, the x chromosome appears monosomic, while no HSR chromosomes or DM's (double minutes) are observed. MDBK cells exhibit an array of applications in the realm of biological research. Their utility extends to 3D cell culture, enabling scientists to recreate complex tissue-like structures for advanced studies. Furthermore, MDBK cells are invaluable in high-throughput screening, facilitating the rapid and efficient screening of compounds or agents for various purposes. Additionally, these cells play a crucial role in toxicology studies, essential for evaluating the safety and potential adverse effects of substances on living organisms.Regarding viral susceptibility, MDBK cells demonstrate receptiveness to several pathogens, including Vesicular stomatitis Orsay (Indiana) virus, infectious bovine rhinotracheitis virus, bovine rhinotracheitis virus, bovine parvovirus, bovine adenovirus 2 and 3, bovine viral diarrhoea virus 1, and parainfluenza three virus. This susceptibility to a diverse range of viruses makes MDBK cells invaluable for investigating viral pathogenesis and evaluating antiviral strategies.

SKU:BHC11100260

  • Viruses: The line was tested and shown to be free of bovine diarrhoea virus (BVD).
  • Virus susceptibility: The cells are susceptibled to bovine diarrhea virus, vesicular stomatitis (Indiana strain), infectious bovine rhinotracheitis virus, bovine parvovirus, bovine adenovirus I and III, and parainfluenza virus 3.
  • Virus resistance: Poliovirus 2
  • Reverse transcriptase: negative
  • Products: Keratin
  • cultureMedium: EMEM (MEM Eagle), w: 2 mM L-Glutamine, w: 2.2 g/L NaHCO3, w: EBSS (Cytion article number 820100a)
  • supplements: Supplement the medium with 10% FBS and 1% NEAA
  • 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: Every 3 days
  • postThawRecovery: Fast
  • 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.
