文献和实验Interactions of Retinol-Binding Protein with Transthyretin and Its Receptor
To study the interaction of retinol-binding protein (RBP) with its plasma carrier, transthyretin (TTR), spectrofluorimetry, and circular dichroism have previously been used. Both these techniques require milligram quantities of the proteins
The retinol carrier retinol-binding protein (RBP) forms in blood a complex with the thyroid hormone carrier transthyretin (TTR). The interactions of retinoid–RBP complexes, as well as of unliganded RBP, with TTR
质,小分子或是金属。当融合有亲和标签的蛋白通过标签-配体作用结合再层析基质上时,通过洗杂步骤,即可去除掉其他的细胞成分。 为了洗脱所需要的蛋白质,通过改变缓冲液的条件,如pH,或通过竞争亲和标签和配体连接的方法来进行。 但怎样的纯化是较为成功的呢?仅达到所需的质量量级,如毫克级(或克级)即可满足吗? 这些并不简单。质在蛋白纯化中同样尤为重要,比如,就蛋白的生物活性和纯度而言,通常会有所要求。 以下我们来讨论并且比较2种技术: His-tag系统和Strep-tag®系统,都使用了亲和层析法来纯化
