Accurate measurement of telomeric 3'-overhang (G-tail) lengths is essential for investigation of the biological effects of telomere dysfunction. G-tail telomere hybridization protection assay (Gt-telomere HPA) has the advantages of being simple to perform, accurate and highly sensitive for G tails as short as 20 nucleotides. Furthermore, Gt-telomere HPA is specific and quantitative for human G tails, and can be used to assay cell lysates as well as genomic DNA.
准确测量端粒3'-末端悬垂(G尾)长度对于研究端粒功能障碍的生物学效应至关重要。G尾端粒杂交保护分析(Gt-端粒HPA)具有操作简单、对短至20个核苷酸的G尾准确且高度灵敏的优点。此外,Gt-端粒HPA对人类G尾具有特异性和定量性,可用于检测细胞裂解物以及基因组DNA。
