Methods for treating a bioprosthetic tissue are described herein. The methods comprise contacting the bioprosthetic tissue with at least one nucleophile and/or at least one electrophile in the presence of a catalytic system comprising at least one or a combination of a fluoride-based salt, a cesium-based salt, a potassium-based salt, a rubidium-based salt, or a carbonate-based salt. The methods may be used to alter functional groups on biological tissue which represent actual and potential calcium binding sites and also processes for cross-linking bioprosthetic tissue. Both processes may be used in conjunction with known fixative techniques, such as glutaraldehyde fixation, or may be used to replace known fixative techniques.
本文描述了处理
生物假体组织的方法。这些方法包括在催化系统(包括
氟化盐、
铯盐、
钾盐、
铷盐或
碳酸盐中的至少一种或其组合)存在的情况下,使
生物假体组织与至少一种亲核物和/或至少一种亲电子物接触。这些方法可用于改变
生物组织上代表实际和潜在
钙结合位点的官能团,也可用于
生物假体组织的交联过程。这两种工艺可与
戊二醛固定等已知固定技术结合使用,也可用于取代已知固定技术。
