Secondary Antibodies
Secondary antibodies are essential detection reagents in immunoassays, serving as signal amplifiers and enabling visualization of target–antibody interactions.
They are designed to recognize the Fc region of primary antibodies raised in different host species—such as mouse, rabbit, goat, or rat—allowing researchers to detect, quantify, and localize target proteins in various assay formats.
Mabstar’s Secondary Antibody Series provides a complete portfolio of enzyme-conjugated (HRP, AP) and fluorophore-conjugated (FITC, Cy3, Cy5, Alexa Fluor®) antibodies optimized for Western blot (WB), ELISA, immunohistochemistry (IHC), and immunofluorescence (IF).
Each antibody is affinity-purified to ensure high specificity, minimal cross-reactivity, and superior signal-to-noise ratio.
Key Features
- Broad species coverage: anti-mouse, anti-rabbit, anti-goat, and anti-rat secondary antibodies
