Oxaliplatin-Resistant Neuroblastoma Cell Lines

Check if the same lab product or an alternative is used in the 5 most similar protocols
The non-MYCN-amplified neuroblastoma cell line SK-N-AS was obtained from ATCC (Manassas, VA, US). The oxaliplatin-resistant SK-N-AS sub-line SK-N-ASrOXALI4000 adapted to growth in the presence of oxaliplatin 4000 ng/mL was derived from the resistant cancer cell line (RCCL) collection (www.kent.ac.uk/stms/cmp/RCCL/RCCLabout.html) and had been established by previously described methods [22 (link)]. In addition, we used an SK-N-ASrOXALI4000 sub-line that had been cultivated for at least 10 passages in the absence of oxaliplatin (SK-N-ASrOXALI4000(-)) as a control. The MYCN-amplified UKF-NB-3 neuroblastoma cell line was established from bone marrow metastases of a stage IV neuroblastoma patient [23 (link)].
All cells were propagated in IMDM supplemented with 10% FBS, 100 IU/ml penicillin and 100 μg/ml streptomycin at 37°C. Cells were routinely tested for mycoplasma contamination. Authentication was performed by short tandem repeat (STR) profiling. DNA was isolated using the QIAamp DNA Blood Mini Kit (Qiagen, Hilden, Germany), and the STR analysis was performed using the PowerPlex 16 System (Promega, Mannheim, Germany) according to the manufacturers' protocols.

SCLC cell lines GLC-2 [17] (link) and -36 [18] (link) were provided by Prof. Dr. L.F.M.H. de Leij (University of Groningen, The Netherlands) and SCLC-24H [19] (link) by Dr. H. Lahm (Thoraxklinik Heidelberg, Germany). SCLC cell line H146 was purchased from American Type Culture Collection (Rockville, USA) and SCLC cell line H1184 from DSMZ (Braunschweig, Germany). Cell lines were maintained in DMEM, 10% fetal calf serum (FCS) or in DMEM/Ham'sF12, 20% FCS (cell line H1184). For DNA profiling, 15 different short tandem repeat (STR) systems and the gender specific amelogenin locus were amplified from 1 to 5 ng genomic DNA in a multiplex-PCR using the PowerPlex® 16 System (Promega, Madison, WI, USA), dedicated to forensic DNA profiling, according to manufacturer's instructions. PCR products were quality controlled utilizing a micro fluidic ‘DNA 7500’ array on a 2100 Bioanalyzer (Agilent, Böblingen, Germany). If quality control was passed, allele detection and identification was performed by capillary electrophoresis performed on a 310 Genetic Analyzer (Applied Biosystems, Darmstadt, Germany). Data processing and analysis was done using the GeneMapper software (v3.2) (Applied Biosystems). The DNA profiles of the cell lines are shown in Table 1.

Cell lines used for Western blotting were obtained from the American Type Culture Collection (ATCC), National Cancer Institute Division of Cancer Treatment and Diagnosis Tumor Repository (Bethesda, MD); or Japan Health Sciences Foundation (Tokyo, Japan) and were authenticated. For authentication, short tandem repeat (STR) profiles were determined for each line using the Promega PowerPlex 16 System. This was performed once and compared with external STR profiles of cell lines (when available) to determine cell line ancestry. Sixteen loci (fifteen STR loci and Amelogenin for gender identification) were analyzed, including D3S1358, TH01, D21S11, D18S51, Penta E, D5S818, D13S317, D7S820, D16S539, CSF1PO, Penta D, AMEL, vWA, D8S1179, and TPOX.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
