摘要:介绍了一种dl-色氨酸的生化光学分辨方法,其中dl-色氨酸酰胺与能够产生酰胺酶的微生物的培养产物或其处理产物相互作用.在混合的dl-色氨酸酰胺中,L-色氨酸酰胺被不对称水解,形成光学活性的l-色氨酸,收率高,几乎所有的d-色氨酸酰胺都没有被水解.在分离l-色氨酸后,剩下的d-色氨酸酰胺很容易被水解,形成光学活性的d-色氨酸,收率高.

摘要:It is provided the synthesis of an aptamer-like encoded oligomer (ALEnOmer), method of producing same and method of preparing a library of ALEnOmes. More particularly, the method of preparing ALEnOmer comprises coupling at least one phosphoramidite monomer with an orthogonal protecting group, and the ALEnOmer produces comprises a DNA coding strand covalently attached to an oligomer through a branching unit, wherein the oligomer has a degree of polymerization at least 5 and is an aptamer.
