About this Product
Cisplatin binding DNA (Protein Data Bank structure: 1a84): a stick frame model at a scale of 5 mm per Ångstrom), suitable for a (small) classroom demonstration, as it is over 20 cm long. This model is relatively cheap because the covalent bonds are modelled at only 2 mm thick, and the hydrogen bonds just 1.25 mm thick; as a result it is rather flexible.
Shapeways have recently (October 2014) decided to raise the price of this item from 25 dollars to 125 dollars. Crazy but noting I can do about it...
