A regularly spaced and self-revealing protein ladder for anti-tag Western blot analysis.
نویسندگان
چکیده
We designed a protein ladder (hereafter referred to as "Mega-tag") that contains 14 of the most commonly used epitope tags fused to molecular weight markers. The Mega-tag ladder can be simultaneously visualized when anti-tag antibodies are used to detect epitope-tagged recombinant proteins in Western blots. The logarithm of molecular weights and relative mobility of the Mega-tag protein ladder are highly correlated (R(2)=0.997±0.00232), indicating that the dye-free Mega-tag protein ladder is accurate. It can also serve as a positive control for anti-epitope tag immunoblots. The Mega-tag protein ladder should provide a convenient and precise tool for Western blot analysis.

Introduction: It was reported that morphine could induce apoptosis in neurons. However, its specific mechanistic pathways remain elusive. The present study was undertaken to determine whether morphine could induce apoptosis in PC12 cells, a neuronal cell line, and the involvement of Bax and Bcl-2, as upstream factors of mitochondrial pathway. Methods: In an experimental study, the viabili...
