1 xcelligence RTCA DP Instrument Flexible Real-Time Cell Monitoring For life science research only. Not for use in diagnostic procedures.
2 The xcelligence RTCA DP Instrument Flexible Real-Time Cell Monitoring The RTCA DP Instrument expands the throughput and application options of the xcelligence Real-Time Cell Analyzer (RTCA) portfolio. Featuring a dual-plate (DP) format, the instrument measures impedance-based signals in both cellular and cell invasion/migration (CIM) assays without the use of exogenous labels. With outstanding application flexibility, the RTCA DP Instrument supports multiple users performing short-term and long-term experiments. Explore the wide range of applications Cell invasion and migration assays Compound- and cell-mediated cytotoxicity Cell adhesion and cell spreading Cell proliferation and cell differentiation Receptor-mediated signaling Virus-mediated cytopathogenicity Continuous quality control of cells The xcelligence System continuously and non-invasively detects cell responses throughout an experiment, without the use of exogenous labels that can disrupt the natural cell environment. Obtain complete, continuous data profiles from cell responses generated during in vitro experiments (Figure 1). Take advantage of real-time data to identify optimal time points for downstream assays. Combine real-time monitoring of cellular responses with complementary functional endpoint assays, and maximize data quality before, during, and after your experiment. Cytotoxicity Analysis in E-Plates RTCA Control Unit RTCA DP Analyzer Figure 1: Reveal cytotoxic effects through continuous monitoring. HT1080 cells were seeded in an E-Plate at two different densities (5,000 and 10,000 cells) and treated 24 hours later with 12.5 nm Paclitaxel, or DMSO as a control. As shown by the Cell Index profile, which reflects cell adherence, the antimitotic effect of Paclitaxel was observed in HT1080 cells that were proliferating, whereas confluent cells showed no response. Compact. Convenient. Versatile. The RTCA DP Instrument consists of two components: the RTCA Control Unit and the RTCA DP Analyzer with three integrated stations for measuring cell responses in parallel or independently. Choose from three types of impedance-based 16-well plates: E-Plate 16 and E-Plate VIEW 16 for cellular assays CIM-PLATE 16 for cell invasion/migration assays Use all three different plate types in any combination. Easily achieve optimal cell culture conditions by placing the RTCA DP Analyzer and plates into standard CO 2 incubators. 2
3 E-Plates for the RTCA DP Instrument More Flexibility. More Data. More Insight. Obtain detailed information about your cells with the versatile RTCA DP Instrument, which supports up to three plates of any type E-Plate 16, E-Plate VIEW 16, or CIM-Plate 16 in any combination. For example, cell invasion/migration assays and cytotoxicity assays or short- and long-term assays may be run simultaneously. E-Plate 16 and E-Plate VIEW 16: Cellular Assays in a 16-Well Format Quantitatively monitor changes in cell number, cell adhesion, cell viability, and cell morphology. Easily add compounds during an experiment. E-Plate 16 Assess short- and long-term cellular effects. With the E-Plate VIEW 16, observe measured changes using microscopes. E-Plate 16 E-Plate VIEW 16 Normalized Cell Index Control 5 µm 100 µm 300 µm Antimycin A administration Time (Hours) 4 h 22 h Control 500 µm Figure 2: Easily visualize cells while measuring cell response with xcelligence System E-Plate VIEW technology. A modified version of the standard E-Plate 16, the E-Plate VIEW 16 enables image acquisition using microscopes or automated cell-imaging systems. For the modification, four rows of microelectrode sensors were removed in each well to create a window for visualizing cells. Approximately 70% of each well bottom is covered by the microelectrodes, providing cell impedance measurements nearly identical to those obtained with the standard E-Plate 16. Both plate types can be used in parallel. 300 µm Antimycin A Figure 3: Continuously monitor cells and determine optimal time points for assessing cytotoxicity. Cell proliferation and cell death were continuously monitored using the xcelligence RTCA DP Instrument. The optimal time points for visual inspection of HeLa cells were determined and images taken 4 and 22 hours after compound treatment using a Z16 Apo Microscope with light base (Leica Microsystems). 3
4 CIM-Plate 16: Quantitative Cell Invasion/Migration Analysis Monitor cell invasion and migration continuously in real time over the entire time course of an experiment. Eliminate time-consuming manual detection (Figure 4). Perform CIM analysis in a convenient one-well system (Figure 5). CIM-Plate 16 Invasion/Migration Analysis in CIM-Plates Figure 4: Quantitatively measure the rate and onset of invasion while concurrently assessing migration. HT1080 cells (2 x 10 4 ) were seeded in the upper chamber of CIM-Plate wells coated with varying dilutions of Matrigel, or in wells with no coating. Serum was added to the lower chamber of selected wells as a chemoattractant. Invasion was observed and migration monitored continuously over a 70-hour period. All serum-starved samples resulted in base-line Cell Index levels, indicating the absence of invasion/migration, while those wells with chemoattractant induced migration. Lid Cells Upper Chamber Gel Layer (user provided) Microporous Membrane Microelectrodes Adherent Cell Lower Chamber Chemoattractant Figure 5: Analyze invasion/migration in real time with the CIM-Plate 16. The plate features two separable sections for ease of experimental setup. Cells seeded in the upper chamber move through the microporous membrane into the lower chamber that contains a chemoattractant. Cells adhering to the microelectrode sensors lead to an increase in impedance, which is measured in real time by the RTCA DP Instrument. 4
5 E-Plate Insert 16: Co-Culture in Real-Time Continuously monitor indirect cell-cell interactions. Assess short- and long-term cell response without labor-intensive labeling and microscopy. Co-culture different cell types under physiological conditions for a broad range of applications, including: Cancer Research: Assess paracrine stimulation of cancer cell proliferation by fibroblasts. Immunology: Investigate immune cell interactions. Stem Cell Research: Monitor proliferation and differentiation in the presence of stimulation cells. Toxicology: Determine cytotoxicity of agents and assess effects of cytokine release. Figure 6. Real-time monitoring of co-culture-induced proliferation stimulation and its inhibition using the E-Plate Insert. Intercellular interactions play an important role in normal cell development and tumorigenesis. Results show that the proliferation of hormone-responsive tumor cells is likely mediated by hormones and growth factors exchanged between the two cell populations separated by the E-Plate Insert. Elevated T47D cell proliferation on the E-Plate (green trace ) was induced by hormone secretion of H295R cells in the insert, and inhibited by the hormone synthesis inhibitor Prochloraz (blue trace ). Incubation of T47D cells with only the E-Plate Insert did not affect proliferation (red trace ). Lid E-Plate Insert E-Plate 16 5
