An antibody. These little things keep us safe.I found the open data base for Protein structures over at http://www.pdb.org/pdb/home/home.do I chose to colour by protein chain as it gave the cleanest result, whilst still conveying some information. I chose to convert some of them and put them on my anthromod shop. The immunoglobulin above is available at http://shpws.me/vO3S I hope to get back to the robot and prosthetic arms soon. But alas have had to get a proper grown up job in the mean time :-(
