Intervertebral disc is a highly specialized cartilaginous tissue, containing two genetic types of collagen (I and II). Analysis of peptides from a CNBr digest of collagen showed that the proportions of I and II varied gradually and inversely across pig annulus fibrosus, with exclusively type I at the extreme outer edge and exclusively type II in the nucleus pulposus.
椎间盘是一种高度特化的软骨组织,含有两种基因类型的胶原蛋白(I型和II型)。对胶原蛋白的溴化氰消化产物中的肽进行分析表明,I型和II型胶原蛋白的比例在猪纤维环中呈逐渐且相反的变化,在最外侧边缘仅为I型,而在髓核中仅为II型。
