The Working Of Cardiac Elisa Kits

by Sally Delacruz

Technological advancement in medicine has helped come up with better diagnostic methods. The <A href="http://www.elisatestkits.com">cardiac Elisa kits</A> are the latest invention in this field. They are enzyme-dependent test devices that help in determining the presence or absence of heart diseases. These equipments are capable of discerning problems in hearts of virtually all animals.

The process of diagnosing illnesses depends on an enzyme reaction that gives its results through exhibiting certain color changes. The enzyme and some antibodies combine with antigens, and subsequently change their color to indicate occurrence of a reaction. With this test, researchers are able to detect both antigens and antibodies.

This process can be used in establishing the presence of foreign bodies in human beings. It is very important since it helps in detecting and treating heart problems before they develop into serious problems. This helps in cutting down the cost involved in diagnosing and treating heart defects. This is because the defects are discovered in their early stages before they become serious problems.

For proper working of these devices precision, sensitivity, accuracy and ability to work on a wide range of problems, and give many details are very important. Sensitivity helps in detecting any slight change in reaction when they are mixed with the samples. Accuracy, on the other hand, is required in ensuring that no errors are made in the experiments. The devices are also supposed to be specific to individual heart problems.

It is also important that the instruments are made in a way that makes them stable. To attain stability, one must cut down on the rate loss of these activities. This is possible through proper storage. Stability can also be achieved through minimizing the effects of the surrounding on the set-up. This means temperature, humidity and pressure have to agree with the standard lab requirements. There should be somebody to control incubator temperatures. If only one person is allowed to work on the research from beginning to end, it will be easy to achieve stability.

For proper working of this activity, the researcher must ensure that all standards, reagents and samples are prepared in advance. The next thing is addition of some samples to all the wells and incubating them for close to 2 hours. He should then aspire and add some reagents. Next, he should put it back in the incubator for an hour, and later aspire and wash the mixture three times. The substrate solution should then be added, and the mixture incubated for a period of between 20 and 25 minutes. After, this step, a stopping agent must be added to stop the reaction for the researcher to make readings.

The enzyme sandwich principle is applied in this experiment. Plates on the kits are coated in advance with specific antibodies for the problem under investigation. Standards or samples are then appropriately added to the plates. They normally contain antibodies which are specific to certain defects. Lastly, Avidin conjugate is put on each plate and then incubated.

After the addition of substrate solutions, it is only the wells that will contain type 3 of Tropin I. The reagents will then show a change in color. The reaction is brought to an end by adding a solution of sulphuric acid, and the change in color is measured is a special style.
