Pulse makes your analytical studies of stem cell-derived cardiomyocytes easy.

Cell and workflow friendly

Use your standard multi-well plates. No dyes, no electrodes. Nothing touches your cells except the compounds you’d like to test.

High-density or single-cell

Plate your cells however you’d like, and Pulse will automatically generate measurements for each distinct beating cell or group of cells.

Configurable and automated

Run the assay once, or tell Pulse to assay every 30 minutes for the next 8 hours. Load your plate, press start, and your results will be waiting for you.

Non-invasive phase contrast microscopy

The Pulse system uses standard phase contrast microscopy with LED illumination to capture high frame rate movies of cardiomyocyte beating. Pulse also comes with a high-quality stage top incubator to maintain a stable environment during imaging.

Image and time-series analysis

As its core technology, Pulse’s patented algorithm analyzes the contraction and relaxation motion patterns of cardiomyocytes to generate a beating profile, from which measurements such as beating frequency, irregularity, and duration are derived. Measurements are automatically derived for each distinct beating region, enabling automated analytical studies of high density and single-cell cardiomyocytes.

Cloud computing and website user interface

Pulse data is automatically uploaded to the cloud. Simply log into the secure Pulse dashboard from any computer or mobile device to view and download your data, movies, and analytical results.

Application

Pulse provides a new technology platform for cardiovascular drug development and cardiotoxicity testing.
