Why is the secondary antibody conjugated with an enzyme for detection in immunoassays?
The secondary antibody is conjugated with an enzyme in immunoassays because the enzyme can produce a detectable signal, such as a color change or light emission, when it comes into contact with a specific substrate. This allows for the visualization and quantification of the target antigen that the secondary antibody has bound to, making the immunoassay results easier to interpret and analyze.

Why is the secondary antibody used in an ELISA test conjugated with an enzyme?
The secondary antibody in an ELISA test is conjugated with an enzyme to amplify the signal produced when the antibody binds to the target antigen. This enzyme-substrate reaction generates a detectable signal that indicates the presence of the antigen, which allows for more sensitive and accurate detection in the ELISA assay.
How do you choose a secondary antibody for your experiment?
When choosing a secondary antibody for your experiment, consider the primary antibody you are using and select a secondary antibody that is specific to the species and isotype of the primary antibody. Additionally, ensure that the secondary antibody is compatible with the detection method you are using, such as fluorescence or enzyme-linked detection. Conducting a thorough literature review and consulting with colleagues or antibody suppliers can also help in selecting the most suitable secondary antibody for your experiment.
How do you choose the appropriate secondary antibody for your experiment?
To choose the appropriate secondary antibody for your experiment, consider the primary antibody used, the species it was raised in, and the detection method. Match the secondary antibody to the species of the primary antibody and ensure it is compatible with the detection method being used. Conduct a thorough literature review and consult with colleagues or antibody suppliers for recommendations.
What is the recommended western blot buffers recipe for optimal protein detection and analysis?
The recommended western blot buffers recipe for optimal protein detection and analysis includes a protein extraction buffer, a blocking buffer, a primary antibody dilution buffer, a secondary antibody dilution buffer, and a wash buffer. These buffers help in efficient protein transfer, blocking non-specific binding, and enhancing antibody binding for accurate detection and analysis of proteins on the blot.
What are the differences between indirect ELISA and sandwich ELISA?
Indirect ELISA and sandwich ELISA are two types of enzyme-linked immunosorbent assays used in laboratory testing. In indirect ELISA, the antigen is immobilized on the surface, and a primary antibody binds to the antigen. Then, a secondary antibody linked to an enzyme is added to detect the primary antibody. In sandwich ELISA, the antigen is captured by a primary antibody that is immobilized on the surface. A second antibody linked to an enzyme is then added to bind to a different epitope on the antigen, forming a "sandwich" complex. The main difference between the two methods is the way in which the antibodies are used to detect the antigen. In indirect ELISA, the primary antibody is detected by a secondary antibody, while in sandwich ELISA, the antigen is "sandwiched" between two antibodies for detection.

What do immunoassays do?
Immunoassays measure the formation of antibody-antigen complexes and detect them via an indicator reaction.
Why two types of antibody are used in western blotting?
In western blotting, two types of antibodies are used to enhance specificity and sensitivity. The primary antibody binds directly to the target protein, allowing for the detection of the protein of interest. The secondary antibody, which is conjugated to a detection enzyme or fluorescent dye, binds to the primary antibody, amplifying the signal and enabling visualization of the protein. This two-step approach improves the overall accuracy and reliability of the assay.
what antibody use in western blot technique?
Generally there are two antibodies used. Primary antibody which can bind specifically to the protein of interest. And a secondary antibody coupled with a detection system such as HRP that would bind the primary antibody and signals the presence of protein of interest.
What is primary and secondary antibody?
primary antibody is what binds to the specific gene that you are interested in looking at; i.e. primary is rabbit-antibody bind to its proper epitope. and this is usually unconjugated with no label. the secondary antibody is conjugated with some type of label, i.e., you will be able to see if your gene is being expressed. i.e., if primary from a rabbit, want goat-anti-rabbit, this way it can bind to the primary antibody.

What is a fluorescent antibody test?
Laboratory tests. the fluorescent antibody test uses fluorescent tags that are attached to antibodies for easy detection.
Why you use serum of animal against which your secondary antibody is raised for blocking the membrane?
It prevents non-specific binding of the secondary antibody, and thus reduced background.
Why is it important that the capture and detection antibodies recognize different epitopes in ELISA?
Capture and detection antibodies must recognise two non-overlapping apitopes in order to work. Once the detection antibody is bound, the capture antibody cannot obscure the epitope used by the detection antibody in any way, or the sandwich ELISA will not work. Hope that helps, I am also trying to answer a similar question and this is what i have found out so far, but not 100% sure that its right. Eve
