The Working Of Cardiac Elisa Kits

By Sally Delacruz


Technology in medicine has taken a new dimension. With regards to testing for presence of diseases and other anomalies, Elisa technology has taken over. The cardiac Elisa kits have been particularly so good. They are devices capable of working with the hearts of almost all animals in the world to establish any defects on it.

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 this experiment to work, one needs to prepare all samples, standards and reagents. He/she should then add a small amount of the sample to every well and then incubate for about two hours. After this, he should aspire then add some reagent and again incubate for about an hour. After this, he must aspire the mixture and wash it three times. The next step is addition of substrate solutions and then incubating for another 20 to 25 minutes. The last step is addition of stop solution and making 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.
