14-120 kDa Protein Marker. Protein Marker is composed of eight prestained proteins ranging from 14 kDa to 120 kDa. The protein of 50 kDa and 120 kDa are covalently coupled to orange dye. The protein of 14 kDa band is covalently coupled to yellow dye. The other five proteins are covalently coupled to blue dye. After SDS-PAGE and transferred to PVDF or NC membrane, clear color protein bands are gained and show the direction at the same time. Five blue bands, two orange bands and one yellow band. MW range from 14 kDa to 120 kDa. Ready-to-use format, no heating and reductant are required.

Research Articles on 14-120 kDa Protein Marker RNA Interference Products RNA干扰（RNA interference, RNAi）是指在进化过程中高度保守的、由双链RNA（double-stranded RNA，dsRNA）诱发的、同源mRNA高效特异性降解的现象。基因沉默，主要有转录前水平的基因沉默(TGS)和转录后水平的基因沉默(PTGS)两类:TGS是指由于DNA修饰或染色体异染色质化等原因使基因不能正常转录;PTGS是启动了细胞质内靶mRNA序列特异性的降解机制。有时转基因会同时导致TGS和PTGS。 由于使用RNAi技术可以特异性剔除或关闭特定基因的表达，（长度超过三十的dsRNA会引起干扰素毒性）所以该技术已被广泛用于探索基因功能和传染性疾病及恶性肿瘤的治疗领域。
