客户应用案例
案例1:基因特异性siRNA
将siASGR1和siCtrl转染到人肝癌细胞系Huh7,结果发现转染siASGR1显著降低了ASGR1的相对mRNA水平。并且导致经典LXR靶基因(包括ABCG5,ABCG8和ABCA1)的表达升高。

案例2:lncRNA特异性siRNA 将两个独立的靶向LINC00680的siRNAs转染KYSE510细胞,结果显示转染si LINC00680显著降低了LINC00680的相对表达,且LINC00680的敲低对细胞增殖的影响最为显著。

案例3:circRNA特异性siRNA 将特异性靶向circEXOC6B的siRNAs转染CRC细胞(SW620、HCT116),结果发现转染si1-circEXOC6B和si2-circEXOC6B显著降低了circEXOC6B的表达水平,并且敲低circEXOC6B显著促进了细胞的增殖。
