ProLiFiler™ Cancer Cell Panel Screening

The ProLiFiler™ service is suitable for testing the therapeutic efficacy of test compounds on a panel of 160 human cancer cell lines using CellTiter-Glo readout.

Our cell line panel screening service can answer numerous research questions:

Which tumor cell lines are sensitive to your drug?
Which cancer types are susceptible to treatment?
What is the genomic signature of your drug for the prediction of anticancer drug response?
Which cancer drugs act similar to your drug for confirmation of the mode of action?

Cell line panel screening provides efficacy data for 160 tumor cell lines from across 15 tumor types. The screening is performed with established cell lines to guarantee robust and reproducible results. Identify the most responsive tumor cell lines for subsequent studies on cellular models or animal studies, all of which can be performed with Reaction Biology.

Advantages of Reaction Biology’s ProLiFiler™:

Performed on a regular basis
Huge cost-savings
Fast turnaround time: get your results in 5 to 6 weeks
Semi-automated processing for highly reproducible data
Single drug or combination drug testing
Option for in-depth bioinformatics analysis

Cell Panel Screening Details

Assay Description

assay principle of the cellular proliferation assay performed with celltiter-glo

Cells were seeded in cell culture-treated 384 multi-well plates in the respective medium (A). After overnight incubation at 37 °C, compounds are dispensed by a Nanodrop Tecan D300e machine (B). Cells are treated for 72 h at 37°C at 5 % CO2 (C). Finally, cell plates are equilibrated to room temperature and the viability of cells is determined with CellTiter-Glo luminescent reagent based on the amount of ATP present (D).

Reproducibility

The semi-automated screening process produces highly reproducible data. In every run, a reference compound serves as the control reference compound. Shown here are the mean data and standard error of results from 4 independent ProLiFilerTM runs.

Assay Setup

Setup: IC₅₀ determination or single concentration testing with CellTiter-Glo readout. Drug combination testing is also an option, see an example study here.

Controls: DMSO-only treatment serves as high control. Staurosporine treatment (at 1×10^-5M) serves as the low control. In every project, the IC₅₀ value determination of a reference compound is included.

Report: A detailed report including assay conditions, methodology, and comprehensive evaluation of data as well as raw data for each analysis will be provided.

Testing of subsets: For testing a subset of cell lines, or single concentration screening of multiple compounds, please see our Cell Proliferation Assay service with the free choice setup here.

Screening facility: The ProLiFiler^TM cell line panel screening is performed in Freiburg, Germany.

Turnaround time: 5 to 6 weeks

Compound requirements: In brief: 100 µl of the stock solution with 1000x the highest testing concentration or the equivalent as solid material.

Please see our FAQ page to access our cell-based assay condition form (German facility) for further details on compound preparation and shipping.

Screening schedule

Please find the screening schedule here. Results are available after 5 to 6 weeks.

Case Study - efficacy in tumor cell lines

met kinase inhibitor on large cell line panel screen

Identification of cell lines sensitive to a MET kinase inhibitor. The MET inhibitor was tested for anti-proliferative and cytotoxic capacity with the ProLiFiler^TM cell line panel. Three cell lines were most receptive to treatment including MKN-45, LOVO, and Karpas 299.

Case Study - Tumor Origins

Identification of the tumor origin most sensitive to a MET kinase inhibitor. IC₅₀ values of the inhibitor potency on a panel of tumor cell lines were sorted based on the tumor entity. Colon tumors (red) were most susceptible to treatment.

Bioinformatic Analysis

Our bioinformatics analysis tools are available to identify the mechanism of action of your test compound and to detect suitable biomarkers for the stratification of responders vs. non-responders.
