The accompanying gel shows cellular lysates which have been well-separated on a gradient gel, and stained with Coomassie dye to visualize all the separated protein bands. If the gel is run at too high a voltage it will overheat and distort the bands. The gel is then connected to a power supply and allowed to run for a few hours in a buffer tank to separate the proteins. Small volumes of protein (5-20 ml) dissolved in gel loading buffer are added to each individual well. High sensitivity (5 pg) colorimetric detection kit, includes optimized 4CN substrate, antibody conjugate, amplification reagents for 2,500 cm 2 of membrane (50 mini blots) List Price: Your Price: Log in to see your price.

Once the gel sets, it is placed into the running apparatus. Amplified Opti-4CN Goat Anti-Mouse Detection Kit. The percentage and the thickness of the gel will impact the transfer of proteins out of the gel in the blotting phase, so using a thinner gel, or a lower percentage of acrylamide, may improve transfer results

Polyacrylamide Gel Percentage Separation Ranges See the table below for some common gel percentages and their separation ranges. Gels can be made with a uniform acrylamide percentage, or with a continuously varying gradient that yields improved resolution over a broader range of molecular weights. Use the Trans-Blot Turbo RTA transfer kit for fast, efficient protein transfer with the Trans-Blot Turbo rapid western blotting transfer system. SDS-PAGE gels (commercially supplied or made in-house) usually consist of a main gel, which is poured between two glass or plastic plates, and which is sometimes topped by a short stacking gel. This makes it possible to clearly identify the target protein later through immunodetection with a specific antibody. This protein blotting system is a powerful tool in the western blotting workflow, enabling the visualization and identification of proteins for downstream analysis.

Applications and Uses of the Trans-Blot Turbo Transfer System. The key is to effect a separation such that the target protein will be properly resolved from the other components of the mixture. Watch this short video to learn more about the Trans-Blot Turbo system. Since the charge to mass ratio is equalized by the binding of SDS consistently along the length of the proteins, and higher structure has been removed, the proteins will be separated primarily by size. Since the samples have been denatured in gel loading buffer containing SDS detergent, the protein is uniformly negatively charged and will now migrate in an electric field through the gel and towards the positive electrode.
