Zika virus Detection with EASE (IMAGE) University of Washington Caption Microscopy images taken of Zika-infected primate placenta samples that were stained to detect Zika using a common laboratory assay, immunohistochemistry. The left image shows a sample treated with the EASE protocol, with red/orange colored signals of Zika infection clearly visible (white arrows). The right image shows a sample treated with a standard protocol, and Zika virus -- though present -- is not detected. Cell nuclei are stained in blue. The white dotted line indicates tissue barriers within the placenta. Scale bar is 100 micrometers.
