Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country. |
| Age： | adult |
| Gender： | male |
| Applications： | This cell line is suitable as a transfection host |
| Storage Conditions： | liquid nitrogen vapor phase |
| Karyotype： | Chromosome Frequency Distribution 50 Cells: 2n = 60. The stemline chromosome number is hypodiploid with 2S component occurring at 5%., There were a total of 11-14 marker chromosomes (4-5 metacentric, 3-4 submetacentric and 4-5 acro-telocentric) common to most hypodiploid metaphases. The X was monosomic. Neither HSR chromosomes nor DMs were seen. |
| Derivation： | The MDBK cell line was derived from a kidney of an apparently normal adult steer, February 18, 1957, by S.H. Madin and N.B. Darby. The cells were originally obtained in July, 1967 at passage 96 from the ATCC as a frozen ampule (F-145).xad |
| Clinical Data： | male |
| Genes Expressed： | keratin |
| Virus Susceptibility： | Vesicular stomatitis, Orsay (Indiana)
Infectious bovine rhinotracheitis Bovine parvovirus Bovine adenovirus 2 Bovine adenovirus 3 Bovine viral diarrhea virus 1 , Bovine viral diarrhea virus 1 Parainfluenza 3 |
| Virus Resistance： | poliovirus 2 |
| Comments： | A specific lot of CCL-22, MDBK (NBL-1) bovine kidney cells was found to be positive for bovine viral diarrhea virus (BVDV), following an investigation by ATCC (Dec. 2015). Testing for BVDV was performed in compliance with the Code of Federal Regulations, Title 9, Section 113.52 (E &F) using virus-specific fluorescent antibody (FA) technique as well as non-specific tests for hemadsorption and cytopathic effects (CPE). Samples were found to be positive for BVDV by FA. Hemadsorption and CPE were not observed in the sample inoculated cultures. xa0As a result, xa0the BSL status for CCL-22 was changed to “2”. xa0 Subsequent lots of CCL-22, MDBK (NBL-1) bovine kidney cells are tested for BVDV and the results will be indicated on the Certificate of Analysis for the lot. The cells are positive for keratin by immunofluorescence |
| Complete Growth Medium： | The base medium for this cell line is ATCC-formulated Eagles Minimum Essential Medium, Catalog No. 30-2003. To make the complete growth medium, add the following components to the base medium: horse serum to a final concentration of 10%.
|
| Subculturing： | Rinse the cell sheet twice with fresh 0.25% trypsin, 0.03% EDTA solution, and remove the trypsin solution. Allow the flask to stand at room temperature for 10 to 15 minutes, add fresh medium, aspirate and dispense into new flasks. Subcultivation Ratio: A subcultivation ratio of 1:2 to 1:4 is recommended Medium Renewal: Twice per week
|
