This method uses Coomasie Brilliant Blue dye, which reacts in the presence of proteins, and the color change is detected in the wavelength range of 465-595 nm. 15
Detailed protocol for the transfer and staining of proteins in western blot. Includes visualization of proteins in gels, transfer, and development methods. Download the complete western blot guide.
7 de nov. de 2019 · The western blot is a common method used to detect proteins as well as post-translational modifications on proteins, and can provide semi-quantitative or quantitative data about the target protein in simple or complex biological samples . Western blotting is an extensively used technique for protein analysis [2–4].
The Western blot (WB) has diverse applications for investigating regulatory molecular events underpinning energy metabolism, protein turnover and chronic physiological adaptations.
Coomassie blue staining can also be used as a loading control staining method in western blot analysis. It is applied as an anionic pre-antibody stain. Medical uses. In 2009, brilliant blue G was used in scientific experiments to treat spinal injuries in laboratory rats.
Both Ponceau S and Coomassie Brilliant Blue stains are negatively charged solutions that bind to positively charged amino acid groups and non-polar protein regions. Ponceau S detects protein levels at 200 ng and higher, and is compatible with PVDF, nitrocellulose, or nylon membranes.
30 de abr. de 2019 · Following this, the samples were used for Coomassie Brilliant Blue (CBB) staining (lane i) or electroblotted onto PVDF (Fig. 1a, top panel) or nitrocellulose membrane (Fig. 1a, bottom panel),...
