The Wonder In Cardiac Elisa Kits

By Sally Delacruz


Advancement in medical technology has brought new ways of detecting heart diseases in the human body. This is through the use of cardiac Elisa kits. These are diagnostic tools that work with samples and reagents in determining the existence of problems in the heart. This is done through looking out for color change in the reagents.

This experiment works when the enzyme immunoassay binds with antibodies and substrate. When this occurs, color changes to indicate presence or absence of trouble. With these tools, it is possible to work with both antibodies and antigens. The amount of both of them can be determined by observing the color changes.

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.

Proper working of this equipment means it is sensitive to reactions, gives accurate results, and is capable of making many detailed readings at a time. When a tool is sensitive, it can exhibit any slight change resulting from the reaction between samples and reagents. Its accuracy ensures that results obtained are free of errors, and hence, believable. They are also manufactured to work on specific problems.

Stability is also important in the working of this equipment. To ensure stability, the loss rate of the activity has to be kept as low as possible. Good storage is also very important in ensuring stability. For the purpose of minimizing the effects of the environment on this experiment, standard lab conditions are very important; room temperature, standard pressure and humidity. The temperatures within the incubator should be closely regulated. It is also important to have one person working on the experiment from beginning to end.

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.

Once the substrate solution has been added, no other part, except the wells, will contain Tropin I type 3. A color change will be exhibited in the reagents. Sulphuric acid is then added with the purpose of bringing the reaction to an end. The change in color is measured in terms of some special wavelengths.
