No additional antibodies / reagents / steps requiredįor more information on storage and use, please refer to the product information. The Protein Ladder allows to monitor molecular weight separation during electrophoresis, estimate molecular weights. This protein marker is prestained and designed for monitoring protein separation during SDS-PAGE verification of western transfer efficiency and approximate. The ladder seems to transfer fine because the pre-stained marker shows up quite well on the membrane.Compatible with ECL, fluorescence and chromophore based detection systems.Immunodetectable: 10 IgG binding proteins.There are numerous variations in western blotting detection that include, but are not limited to, the previously mentioned strategies. Prestained: 4 colored bands for visual control on gel and membrane far-western blot, is routinely used for the discovery or confirmation of a proteinprotein interaction.

The result: c lear band assignment and no inaccuracies due to manual marking.Ī must for the perfect western blot! All the advantages at a glance: This enables marker visibility with whatever detection method is used. Chromogenic Western Blot kit with increased signal and sensitivity. Sizes range from 10 to 250 kDa which is ideal for accurate molecular weight determination for a wide range of expressed proteins. Via these IgG binding sites, the primary/secondary antibody binds to the marker proteins during antibody incubation. Our Protein ladder is designed for monitoring protein separation during SDS. The BLUelf Prestained Protein Ladder is a three-color protein standard with 13 prestained proteins covering a wide range molecular weights from 3.5 to 245. How it works? The proteins used in the marker contain IgG-specific binding sites.

The protein ladder is supplied in a ready-to-use format for direct loading onto gels no need to heat, reduce, or add. With the WesternFroxx all-in-one Protein Ladder (15 – 200 kDa) for immunodetection we offer you a protein size standard that is not only pre-stained, but also detectable by antibody detection methods analogous to the target protein. Thermo Scientific PageRuler Plus Prestained Protein Ladder is a mixture of nine blue-, orange-, and green-stained proteins (10 to 250 kDa) for use as size standards in protein electrophoresis (SDS-PAGE) and western blotting.
