Methods for dissolving a biopolymer in an ionic liquid are also disclosed. A recovery solvent is used to reduce the solubility of the biopolymer in the ionic liquid and conventional separation ... 10/19/06 - 20060235205 - Process for preparing porous collagen matrix from connective tissue The subject invention provides a process for preparing a porous collagen matrix from connective tissue, said process comprising: a porous structure forming step to treat said connective tissue with poring agent in situ; and a washing step to remove the impurity from said porous connective tissue thereby obtaining a porous ... 07/06/06 - 20060149040 - Collagen and method for producing same The present invention relates to a method for producing collagen from an animal skin. In particular, the present invention a method for producing collagen from an animal skin comprising the step of applying to said skin an organic acid buffer for sufficient time to enable the extraction of collagen. ... 12/01/05 - 20050267292 - Extraction of collagen from calcified tissues A method is disclosed for extracting collagen from calcified tissue without a prior decalcification step. The method may be used with calcified tissues such as fish skin with scales, alligator skeletons, and crustacean exoskeletons. It does not require the use of EDTA. When fish skin is used that contains substantial ... 09/01/05 - 20050192428 - Mutated recombinant collagens The invention provides recombinant procollagen chains having a natural collagen chain separated from one or two propeptide by one or two non-natural site-specific proteolytic agent (e.g., protease) recognition sites. A wide variety of propeptides and site-specific proteolytic agent recognition sites may be used: the selection of particular site-specific proteolytic agent/recognition ... ### FreshPatents.com Support |
