In the Indirect ELISA ,
- An antigen is added to the microtiter plate well and the antigen attaches to the walls of the microtiter plate.
- After rinsing to remove excess antigen, the serum suspected of containing the antibodies is added.
- Enzyme-linked antibody capable of reacting with the constant region of other antibodies is the added, followed by addition of the colorless substrate. Development of color indicates the presence of the antibody being identified.

What does the name Elisa mean?
Elisa means "consecrated to God"
Why are direct elisas sometimes referred to as sandwich elisas?
Direct ELISAs are sometimes refered to as sandwich ELISAs because unlike the indirect ELISA in which the antigen is binded nonspecifically to the ELISA plate, an antibody is first plated that will capture the antigen. Next, an enzyme-linked antibody is plated and lastly a substrate which creates a measurable color change (OD). The two antibodies "sandwich" the antigen.
What are the Various enzyme used in ELISA?
There is just one enzyme used in the ELISA reaction. This enzyme is linked to the secondary antibody. Commonly used ELISA enzymes are:Alkaline phosphataseHorseradish peroxidase
Who was Elisa Mcnabney?
Laren Sims Jordan
What is the full form of ELISA?
enzyme linked immunosorbant assay
What is the difference between direct and indirect ELISA?
In direct ELISA, the primary antibody is directly linked to an enzyme for detection, while in indirect ELISA, a secondary antibody linked to an enzyme is used to detect the primary antibody bound to the antigen. Direct ELISA is quicker and more straightforward, but indirect ELISA allows for signal amplification and detection of multiple antibodies bound to the antigen.
What is ELISA testing?
ELISA is an acronym for Enzyme Linked ImmunoSorbent Assay and is used in a wide variety of applications, including detecting antibodies from HIV.

In indirect elisa the enzyme liked antibody will attach to?
In an indirect ELISA, the enzyme-linked antibody attaches to the target antigen that has been immobilized on the microplate. This allows for the detection of the antigen through the enzyme's activity, which produces a signal that indicates the presence of the target antigen in the sample.
What is Elisa used for?
Elisa (Enzyme-Linked Immunosorbent Assay) is a common laboratory technique used to detect the presence of antibodies or antigens in a sample. It is widely used in medical diagnostics, food testing, and research settings to identify and quantify specific molecules.
