How do you choose a primary antibody?
Check that the immunogen is identical to or contained within the region of the protein you are trying to detect. For example, if you are trying to detect a cell surface protein on live cells by FACS, choose an antibody that is raised against an extracellular domain of the protein.
What type of antibody is recommended to use in Western blots?
Polyclonal, monoclonal and recombinant antibodies all work well for western blotting.
What is the role of primary and secondary antibody in western blot technique?
The primary antibody recognizes and binds the epitope or the specific amino-acid sequence of the protein of interest. Secondary antibodies used for western blotting are typically conjugated with an enzyme; the most commonly used enzymes are Horse Radish Peroxidase (HRP) and Alkaline Phosphatase (AP).
What is the purpose of using a secondary antibody in western blot?
A secondary antibody aids in the detection, sorting or purification of target antigens by binding to the primary antibody, which directly binds to the target antigen.
What is the purpose of the primary and secondary antibodies?
The primary antibody detects the antigen in the specimen, but the secondary antibody can be designed to have a fluorophore or enzyme complex attached to it for the purposes of visualization.

How do I choose a secondary antibody for ICC?
- Host and target species.
- Targeted reactivity.
- Purification.
- Cross-adsorption.
- Multiplexing.
- Antibody class and subclass.
- Whole antibodies vs. fragments.
- Conjugates.
Is it better to use monoclonal or polyclonal antibody for western blot?
monoclonal antibodies may be better than polyclonal antibodies is certain clinical and research applications. But when used as the primary antibody in Western blotting or immunohistology procedures.
Why primary antibody is used in western blotting?
The primary antibody recognizes and binds the epitope or the specific amino-acid sequence of the protein of interest. Secondary antibody: After washing to remove unbound primary antibody, secondary antibody is added. Secondary antibody recognizes the primary antibody.
