    摘要: An apparatus for the storage of a protein (20) comprising a first compartment (30) for storing the protein (20) and a second compartment (40) for storing an alkaline buffer (50), the second compartment (40) being in fluid communication with the first compartment (30) is described. In one preferential embodiment of the invention, the alkaline buffer comprises calcium ions which encourage the gelling of the protein (20). A method for the storage of a protein (20) is also described. The method comprises: a first step of placing the protein in a first storage compartment (30); a second step of exposing the protein (20) to an alkaline buffer (50); and a third step of maintaining the protein (20) in the alkaline atmosphere in the first storage compartment (30).

    摘要: The invention utilizes the sol-gel transition behavior of certain proteins for forming objects. The invention is directed to a method and apparatus for forming an object from a feedstock made of a protein solution, the protein undergoing a sol-gel transition and comprising the following steps: a first step of adjusting the conditions to cause the feedstock to flow to form the object from with the protein substantially in the sol state, a second step of adjusting the conditions of the feedstock either to gel the feedstock or bring it close to the sol-gel transition point. Particularly preferred proteins are spidroin and fibroin, while one of the conditions of the feedstock will be adjusting the pH of the solution e.g., with a carboxylic acid.
