The antibody solution metode elisa can be removed by flicking the plate over a suitable container. The remaining sites for protein binding on the microtiter plate must be saturated by incubating with blocking buffer.


Incubate for 2 h metode elisa overnight in a humid atmosphere at room temperature. Sodium azide is an inhibitor or horseradish peroxidase. Do not include sodium azide in buffers or wash solutions if an HRP-labeled antibody will be used for detection.

Prinsip ELISA

Wash wells twice with PBS. Incubate for at least 2 h at room temperature in a humid atmosphere. Wash the metode elisa four times with PBS. Add the metode elisa second antibody. The amount to be added can be determined in preliminary experiments.

For accurate quantitation, the second antibody should be used in excess.

All dilutions should be done in the blocking buffer. Incubate metode elisa 2 h or more at room temperature in a humid atmosphere. Wash with several changes of PBS.

Add metode elisa as indicated by manufacturer. After suggested incubation time has elapsed, optical densities at target wavelengths can be measured on an ELISA plate reader.


Some enzyme substrates are considered hazardous, due to potential carcinogenicity. Handle with care and refer to Material Safety Data Sheets for proper handling precautions. The metode elisa dilution should be determined using an metode elisa titration prior to testing samples.

ELISA - Wikipedia

Allow to incubate for 4 hrs. If a purified capture antibody is not available, the plate should first be coated with a purified secondary antibody directed against the host of the capture antibody according to the following procedure: Add primary capture antibody as above.

A mL squirt bottle is convenient. Incubate for 2 hrs. Do not include sodium azide in buffers or wash solutions, metode elisa an HRP-labeled conjugate will be used for detection.

The antigen-containing sample is applied to the plate, and captured by antibody.

The plate is washed to remove unbound antigen. A specific antibody is added, and binds to antigen hence the metode elisa This primary antibody could also be in the serum of a donor to be tested for reactivity towards the antigen.

Enzyme-linked secondary antibodies are applied as detection antibodies that also bind specifically to the antibody's Fc region nonspecific. The plate is washed to remove the unbound antibody-enzyme conjugates.

A chemical is added to be converted by the enzyme into a color or fluorescent or electrochemical signal. The absorbance or fluorescence or electrochemical signal e.

The image to the right includes the use of a secondary antibody conjugated to an enzyme, though, in the technical sense, this is not necessary if the primary antibody is conjugated to an enzyme which would be direct ELISA.
