LMB 365 – Day 145

On day 145 of #LMB365, a detailed close-up of the 1960s vertical wire model of haemoglobin. This ‘working’ model was made for Max Perutz and its vertical wires and graph-paper-like baseboard allowed precise coordinate measurements to be made for comparison with the electron density map from X-ray crystallography. This means that it was not just a model for display but an important research tool.
