RBL18
ACC 913
Cell line:
RBL18
DSMZ no.:
ACC 913
Species:
human (Homo sapiens)
Cell type:
retinoblastoma
Origin:
established before 1989 from a unilateral retinoblastoma isolated from the primary tumor of the eye of a 15-month-old boy after pretreatment; the RB1 gene is inactivated by mutation (M484Vfs*8), loss of heterozygosity and subsequent duplication of the mutant allele
Biosafety level:
1
Permissions and restrictions:
DSMZ Cell Culture Data:
Morphology:
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:
cells are difficult to culture; aggregates are sensitive to destruction by pipetting; use pipettes with wide opening (serological, wide-bore or cut); cultivate in 6-well plates; seed out all cells into 1 well in 4 ml medium; perform partial medium changes every 3 to 5 days; when aggregates reach a size of 1 to 1.5 mm, split 1:2 to 1:3 once a week by 2-3 times pipetting; protocol
Incubation:
at 37 °C with 10% CO2
Doubling time:
about 9 days
Harvest:
aggregates in one well of a split-ready 6-well plate may contain 4 to 8 x 106 viable 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 (exon 16 M484Vfs*8; chr13:48380193_48380194delAT (hg38)) was verified by Sanger sequencing of all exons and flanking regions; loss of heterozygosity was determined by microstallite analysis for chromosome 13 and copy number of 2 for chromosome 13 was confirmed by methylation-sensitive MLPA
