Is your current in vitro assay truly predictive of in vivo outcomes?

In addition to being robust and simple, the ideal immune cell killing assay closely mimics activity in vivo. To gain a more complete view of cancer cell killing, the xCELLigence® Real Time Cell Analysis (RTCA) technology captures dynamic cell behavior that can be missed by labor-intensive endpoint methods.

How is xCELLigence RTCA used for killing assays?

The xCELLigence® Real-Time Cell Analysis (RTCA) instrument monitors cell killing in real time. Simply add target and immune effector cells to the patented microtiter plates (E-Plates®), load the instrument, and start reading.

The biosensors embedded in the bottom of each well allow for the automated kinetic measurement of changes in cell number, cell size, and cell-substrate attachment quality.

Target cell death can be measured continuously and automatically, from hours to days, without the use of labels.

Reap the benefits of game-changing predictivity with xCELLigence® Real-Time Cell Analysis (RTCA) instruments:

      • Label-Free: No 51Cr, no luciferase, no dyes…NO PROBLEM
      • Astonishingly Simple Workflow: Plate target cells, add effector cells, and start reading
        • Read an entire 96-well plate in 15 seconds
        • Run up to 6 plates independently, with no scheduling conflicts
        • Monitor target cell killing continuously from seconds to days
      • Exquisite Sensitivity: Monitor target cell killing at low, physiologically relevant effector:target ratios
      • Diverse Effector Cells and Molecules: TIL, NK, CART, TCR, checkpoint inhibitors, BiTEs, etc.
      • Quantitative, Real-Time Kinetics: Highly accurate and highly reproducible 
Simple and High Throughput Workflow

The xCELLigence® Real-Time Cell Analysis (RTCA) instruments utilize patented microtiter plates (E-Plates®) which contain gold biosensors embedded in the bottom of each well. These biosensors continuously and non-invasively monitor changes in cell number, cell size, and cell-substrate attachment quality.
