Cell line: | RBL15 |
DSMZ no.: | ACC 943 |
Species: | human (Homo sapiens) |
Cell type: | retinoblastoma |
Origin: | established in 1986 from a primary bilateral retinoblastoma of a 11-month old girl after enucleation |
Reference(s): | 40359, 40298, 40297, 40300 |
Biosafety level: | 1 |
Permissions and restrictions: | A |
| DSMZ Cell Culture Data: |
Morphology: | cells grow in spheroids in suspension; after thawing as single cells and later in aggregates of several mm with nodular structures; image; image |
Medium: | 85% DMEM (with 4.5 g/l glucose) + 15% h.i. FBS + 10 µg/ml human insulin + 2 mM L-glutamine + 1 mM sodium pyruvate + 50 µM mercaptoethanol |
Subculture: | seed out all cells into one well of a 6-well plate with about 4 ml medium; in the first 1-3 weeks do not split but replace 50% of the medium once or twice a week; then split 1:2 to 1:3 once a week; aggregates are sensitive to destruction by pipetting; use pipettes with wide opening (serological, wide-bore or cut) protocol |
Incubation: | at 37 °C with 10% CO2 |
Doubling time: | about 5-7 days |
Harvest: | aggregates in one well of a split-ready 6-well plate may contain up to 6 x 106 cells |
Storage: | frozen with 70% medium, 20% FBS, 10% DMSO |
| DSMZ Scientific Data: |
Mycoplasma: | negative in PCR assay |
Authenticity: | STR analysis according to the global standard ANSI/ATCC ASN-0002.1-2021 (2021) resulted in an authentic STR profile of the reference STR database. |
Molec. Genetics: | Methylation status of the RB1 promoter (CpG106) and differentially methylated region CpG85 (RB1 intron 2) was determined by methylation-senstive PCR (CpG106: 0%, CpG85: 100%); RB1 mutation status (allele 1: exon 10 R320*; chr13:48367512C>T(hg38); allele 2: exon 23 L797* Chr13:48465269T>G (hg38)) was verified by Sanger sequencing of all exons and flanking regions; heterozygosity was determined by microstallite analysis for chromosome 13 and copy number of 2 for chromosome 13 was confirmed by methylation-sensitive MLPA |
