Breakthrough qPAINT Technology Provides Super-Vision to Microscopes

Knowing the exact number of molecules located at specific junctures in cells can be a critical measure of health as well as disease. For example, abnormally high numbers of growth factor receptors on cells can be an indication of cancerous and precancerous states; specific proteins located at the junction where neurons connect in the brain may affect brain function as they accumulate or disperse.
