Fluorescence Microscopy

Using fluorescence microscopy, scientists tracked the uptake of BetaRight WGP (bright green) by immune cells called macrophages (left). The macrophages break down the BetaRight WGP into smaller fragments that bind to the surface of white blood cells called neutrophils (right), activating these key immune cells to protect the body against a wide range of challenges.
