The fluorescent proteins (yellow and cyan) are derived from jellyfish, while the rubber band part (black) has utilized spider web protein. The target protein-binding antibodies (dark brown) are derived from alpacas. The image to the right is a comparison of super-resolution microscopy and conventional microscopy imaging of the cell nucleus.
