COLLAGENASE TYPE V-S

Immunoassays for Collagenase-Mediated Cleavage of Type I and II Collagens

This chapter describes the production and characterization of antibodies raised against neoepitopes in collagenase-cleaved collagen. It also details the development, validation, and use of immunoassays using such antibodies to measure

Production and Crystallization of Bacterial Type V Secretion Proteins

and the production of diffracting crystals. Since the type V secretion pathway involves unusually large substrate proteins (passenger domains or TpsA) and membrane proteins (β-barrel domains or TpsB), crystallography of type V secretion proteins deals with additional

外木型 ectoxylar type

　　 指内部为韧皮部，其外侧排列着木质部的维管束或中柱的类型。为外韧型的对应词，这只不过是现象，而所谓外韧型却完全是另一系统的类型。在并立维管束中，位于内侧的木质部其切面扩展为 V型，把外侧的韧皮部夹在其中，直至包围在外侧。与外韧型比较，它是次生的。普遍存在于单子叶植物百合目的根茎中（例如君影草根茎的中柱）。
