Pleasanton, CA, 2019-Aug-21 — /EPR Network/ — An enzyme-linked immunosorbent assay, also called ELISA or EIA, is a test that detects and measures antibodies in your blood. This test can be used to determine if you have antibodies related to certain infectious conditions…. An ELISA test may be used to diagnose: HIV, which causes AIDS.

Elisa Principle and Procedure – ELISA is an antigen antibody reaction. In 1971, ELISA was introduced by Peter Perlmann and Eva Engvall at Stockholm University in Sweden. It is a common laboratory technique which is usually used to measure the concentration of antibodies or antigens in blood.

ELISA plate coating protocol is based assay technique which is used for detecting and quantifying substances such as peptides, proteins, antibodies and hormones. An enzyme conjugated with an antibody reacts with colourless substrate to generate a coloured product. Such substrate is called chromogenic substrate.

Among the 3 types of ELISA, namely Indirect ELISA, Sandwich ELISA and

Competitive ELISA, you will find that Sandwich ELISA Antigen can be detected by sandwich ELISA troubleshooting. In this technique, antibody is coated on the microtiter well. A sample containing antigen is added to the well and allowed to react with the antibody attached to the well, forming antigen-antibody complex. After the well is washed, a second enzyme-linked antibody specific for a different epitope on the antigen is added and allowed to react with the bound antigen.

The advantages of these sandwich ELISA procedure consists of:

• High specificity, since two antibodies are used the antigen is specifically captured and detected.
• Suitable for complex samples, since the antigen does not require purification prior to measurement.
• Flexibility and sensitivity, since both direct and indirect detection methods can be used.

About Antibody ELISA:

Modern medicine recognizes the complications of treating infectious diseases. It is realized that early diagnosis of diseases is extremely important these days.

Connecting particular proteins to specific disease continues to pose challenges to science even today, though a lot of developments have taken place in past. ELISA can be used to probe numerous diseases in several organisms. The ELISA is a simple test that produces dependable data in a short span of time. ELISA or Enzyme- link immunosorbent assay is the technique used to detect the presence of antibodies in the blood. In some instances, this test is not just for patience but also for plant pathology and quality control in various industries.
