  • Product overview

    Abcam’s DoubleStain IHC Kit: M&R on human tissue (HRP/Green & AP/Red) (ab210061) is designed to detect two distinct antigens on human tissue or cell samples using a simplified protocol with user-supplied mouse and rabbit antibodies. This kit has been tested in paraffin embedded tissues. However, this kit can be used to stain frozen specimen and/or freshly prepared monolayer cell smears.

    Double staining is a common method used in immunohistochemistry to evaluate two distinct antigens in a single tissue. This kit contains a HRP-Polymer anti-Mouse IgG, AP-Polymer anti-Rabbit IgG, and two distinct chromogens, Emerald (green) and Permanent Red (red). User may apply the two enzyme conjugates onto the specimen at the same time and mix them on the slide. Simplified steps offer user much faster and quicker protocol than a sequential procedure. A second advantage is it allows the researcher to visualize when two proteins are co-localized because of the color change when the chromogens overlap that can be semi-quantitative. For example, if the area of co-localization stains blue, the antigen indicated by Emerald is expressed at higher concentration in the cell and if the color is purple, the antigen indicated by Permanent-Red is expressed at higher concentrations DoubleStain IHC Kit: M&R on human tissue (HRP/Green &AP/Red) is a non-biotin system that avoids endogenous biotin non-specific binding.

    The Organic Mounting Medium is not supplied with the 120 mL kit.

    The Permanent Red working solution is not stable. It must be used (freshly) immediately after it is made.
