Sizing of proteins on SDS-PAGE and Western blots.Īpproximately 0.1~0.4 mg/ml of each protein in the buffer (20 mM Trisphosphate, pH 7.5 at 25☌), 2 % SDS, 0.2 mM Dithiothreitol, 3.6 M Urea, and 15 % (v/v) Glycerol.

Monitoring of protein transfer onto membranes during Western blots.

Monitoring of protein migration during SDS-PAGE.

Easy to identify: includes the ~25, ~75 kDa reference bands coupled with a green and a red dye.

Ready-to-use: supplied in a loading buffer for direct loading on gels.

Broad range: 10-245 kDa (Tris-glycine-SDS running buffer).

(C) M: Prestained marker (PageRulerTM Plus Prestained Protein Ladder, Cat 26619. The ladder is supplied in gel loading buffer and is ready to use. In Western blot and positive clone was analyzed in SDS-PAGE. Western blot means you transfer the proteins from the gel for gel electrophoresis (so after you separated them either by size, shape and charge (native polyacrylamide gel electrophoresis - native PAGE) or by size only (SDS-PAGE)) onto a nitrocellulose or PVDF membrane and then visualizing your protein of choice using antibodies against it. Biotinylated protein ladder detection pack is designed to detect the molecular weight ladders on Western blots when using the horseradish peroxidase (HRP) based Western detection system. Size: 500 l Range: 10-180 kDa (Tris-glycine-SDS running buffer) Number of Bands: 10 Feature: three-color, with a green dye at 25 kDa, and a red.

The BLUeye Prestain ed Protein Ladder is designed for monitoring protein separation during, verification of Western transfer efficiency on membranes (PVDF, nylon, or nitrocellulos e) and for approximating the size of proteins. Proteins are covalently coupled with a blue chromophore except for two reference bands (one green and one red band at 25 kDa a nd 75 kDa respectively) when separated on SDS-polyacrylamide gel electrophoresis (SDS-PAGE) with Tris-glycine-SDS running buffer. Familiarize yourself with the protocol and check the common pitfalls below. Western blotting can give you information about the size of your protein (with comparison to a size marker or ladder in kDa), and also give you information. The BLUeye Prestained Protein Ladder is a three-color protein standard with 12 prestained proteins covering a wide range molecular weights fro m 10 to 245 kilodalton (kDa). All bands, including the ladder, are faint or have no signal If all the bands on your blot including the molecular weight ladder are difficult to see, it could indicate a problem with your technique rather than the protein you’re trying to detect. 膠體影像系統Gel Imaging and Documentation Systems (1) I am a beginner of western blot and from some days I have been facing a lot of problems.Does not rely on strep-tagged HRP or secondary antibody binding. Fits with your current protocol without optimization. 電泳膠染劑 DNA Electrophoresis Gel Stains (2) The WesternSure chemiluminescent protein ladder is the only pre-stained, multi-colored protein ladder for both film and digital chemiluminescence detection.
