Applications
- Western blot: Typically uses horseradish peroxidase (HRP), alkaline phosphatase (AP), or fluorescent dye-conjugated antibodies.
- Immunofluorescence: Employs antibodies conjugated to fluorescent dyes (eg, Alexa Fluor).
- Fluorescent immunohistochemistry, singleplex: Uses antibodies labeled with a fluorescent dye.
- Fluorescent immunohistochemistry, multiplex: Relies on multiple fluorescent dyes or oligonucleotide-conjugated antibodies.
- Chromogenic immunohistochemistry: Utilizes HRP, AP, or biotin-labeled antibodies.
- Flow cytometry: Uses antibodies conjugated to fluorescent dyes (eg, Alexa Fluor), fluorescent proteins (phycoerythrin, allophycocyanin), or tandem dyes to analyze and sort cell populations based on marker expression.
- ELISA & ELISA-based applications: Involves HRP- or biotin-conjugated antibodies.
- Lateral flow assay: Uses antibodies conjugated with latex or gold nanoparticles and sometimes fluorescent nanoparticles (e.g., Europium).
What is an antibody conjugate?
An antibody conjugate is an antibody chemically linked to a specific label, such as a fluorescent dye or enzyme, that enables the detection, visualization, or quantification of a target antigen in various assays.
What is the difference between a conjugated and unconjugated antibody?
A conjugated antibody has a detectable label (a fluorescent dye or enzyme) chemically attached to it, whereas an unconjugated antibody lacks any direct label and typically requires a secondary detection method.
How are conjugated antibodies used in flow cytometry?
In flow cytometry, conjugated antibodies (typically labeled with fluorescent dyes or proteins) bind specific cell surface or intracellular antigens, and when these labeled cells pass through the cytometer’s laser, the fluorophores are excited and emit light that is detected, thereby allowing for the identification and quantification of various cell populations and their protein expression profiles.
What is the role of conjugated antibodies in immunofluorescence microscopy?
In immunofluorescence microscopy, conjugated antibodies specifically bind to target antigens within cells or tissues and, due to their attached fluorescent label, allow visualization of the antigen’s location and distribution when excited by the appropriate wavelength of light.
What are the benefits of using conjugated antibodies?
Conjugated antibodies simplify detection protocols, enhance specificity, and enable multiplexing by directly linking a detectable label, thereby saving time and improving sensitivity in various immunoassays.
