應用

伯胺的硫醇化试剂;在温和条件下可使硫醇去保护。通常在 pH 为 7.5 时引发耦合反应,通过酰胺键生成含伯胺的分子。在中性 pH 时可与 0.05M 羟胺发生去保护反应。用于制备酶免疫交联剂和半抗原载体分子偶联物。

其他說明

注意,与其他硫醇化试剂相比,对伯胺的酯偶合作用非常有效。此外,这种试剂可以中和伯胺的正电荷。

Methods are described for the preparation of anionic and cationic liposomes and proteoliposomes with covalently linked lectins or antibodies by the extrusion technique (vesicles by extrusion, VETs). The liposomes are prepared from the phospholipid dipalmitoylphosphatidylcholine (DPPC), together with the anionic
