用于从细胞裂解液和组织中小规模分离mRNA的亲和基质。此分离是通过 Oligo d(T)25与大部分真核生物mRNA中携带的ploy(A)形成共价杂交耦联实现的。既可用于细胞裂解后mRNA的直接分离，也可用于从总RNA中进行第二轮纯化。磁珠分离技术还能放大体系并将分离后的mRNA终体积进行调整，从而得到较小体积的完整RNA 洗脱液，不需要再从洗脱液中沉淀 poly(A)+ 转录物。磁珠能再生3次，实验者可选择将分离到的mRNA洗脱或直接以结合mRNA上的d(T)25 DNA为引物来进行cDNA 链合成。1 mg Oligo d(T)25能结合10 μg poly(A)+ RNA。

用于从细胞或组织中分离完整的poly(A)+RNA，不需酚和其它有机溶剂。将Oligo d(T)25与1 μm顺磁性磁珠耦联后，以此为固相支持物直接结合poly(A)+ RNA。可进行多个样本的分离，自动化高通量分离。磁性分离技术可得到较小体积的完整RNA洗脱液，不需要再从洗脱液中沉淀 poly(A)+ 转录物。因此在 1 小时内就能分离得到体现原始样品中mRNA分布特性的完整poly(A)+ RNA。Oligo d(T)25 磁珠可再生3次，实验者可选择将分离到的 mRNA 洗脱下来或直接以结合于mRNA上的dT DNA 为引物来进行cDNA 链合成。
