Affimers – small probes for big imaging experiments

Posted by Laura Hankins, on 9 August 2022

Antibodies have been used to label proteins of interest since the 1970s. However, their large size (around 15 nm long for IgG) makes the penetration of dense structures within the cell a challenge and places the fluorophore away from the target protein. This latter issue, known as a ‘linkage error’, particularly impacts accuracy and precision
