查询词典 amino acid

Anti-histidine-tag antibody is usually used for identification of expression of the recombinant protein expressed using pRSET-A. A pair of primers that contained flanking hydropathic amino acid codons were synthesized, to amply the sequence coding for 10~34 aa in the precursor sequence.

质粒pRSET-A是一个常用的高效原核表达载体，编码一N端含组氨酸标签（6×His）的34aa前导肽序列，以方便利用抗组氨酸标签抗体鉴定或纯化所表达的重组蛋白。

A pair of primers that contained flanking hydropathic amino acid codons were synthesized, to amply the sequence coding for 10~34 aa in the precursor sequence. The amplified fragment was inserted into pRSET-A to generate the first double repeat of the precursor gene. By utilizing a pair of isocaudamer BamH I and Bgl II sites, and another downstream Hind III site of plasmid pRSET-A, following a series of simple double digestions and ligation of the resulted products, a series of repeat (3, 4 and 6) precursor peptide fragment genes were derived.

本实验设计一对两侧含编码疏水性氨基酸密码子的引物，经过扩增前导序列10~34aa基因序列，并重新克隆入质粒pRSET-A构建串联二聚体后，再利用质粒pRSET-A的BamH I / Bgl II同尾酶克隆位点，经一系列简单的酶切和连接，快速构建这一前导肽中不含组氨酸标签序列的串联多聚体基因，并成功表达其六聚体重组蛋白。
