2-Color IHC Kit for Goat/Rat Antibody on Human/Mouse Tissue, Brown/Red
In immunohistochemistry, the technique of double staining is widely employed to simultaneously detect and differentiate two distinct antigens within a single tissue sample. The 2-Color IF Kit is designed to use DAB (brown) and Permanent Red (red) dye effectively stain 2 different antigens on human and mouse tissue or cell samples when paired with user-supplied goat and rat primary antibodies.

Usage
The kit offers two polymer enzyme conjugates: HRP polymer anti-Goat IgG and AP polymer anti-Rat IgG. These conjugates are accompanied by two distinct substrates/chromogens: DAB (brown color) and Permanent Red (red color).
Applications
Paraffin tissue (verified), frozen specimen and freshly prepared monolayer cell smears.
Color
DAB (brown) and Permanentred (red)
Specificity
Goat and Rat
Tissue Species
Human and Mouse
Storage
2-8℃
Note
The outcome is significantly influenced by several factors, including fixation, tissue slide thickness, antigen retrieval, as well as the dilution and incubation time of the primary antibody. It is crucial for the investigator to carefully evaluate all of these variables and establish the ideal conditions in order to accurately interpret the results.
Principle
The user will sequentially apply the two enzyme conjugates onto the specimen. When both proteins are present, a distinct brown/red color will develop, depending on the presence and location of the antigens. If only the anti-goat antigen is present, only the DAB brown chromogen will be detected. If the Rat antigen is present, only the Permanent Red chromogen will be observed. The kit is a non-biotin system that avoids non-specific binding of endogenous biotin.
