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 exercise is capable of detecting antibodies and antigens in patients. This is very useful; it helps detect illnesses before they develop into chronic problems. Doctors are able to work on it during its early stages of development. The patient will, therefore, be able to eliminate the problems at an affordable value.

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.

The device should also be stable. This is achieved through reducing the loss rate as much as may be possible. The tools should be stored in good conditions to ensure that they remain stable. Other environmental influences should be completely avoided. Appropriate environmental conditions should, therefore, be provided. These include; appropriate temperature, pressure and humidity. Somebody should be given the responsibility of controlling the temperature in the incubator at all times. Assigning one person to work on the experiment is also crucial in ensuring stability.

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.

This process applies the sandwich enzyme principle. The plate that comes with the kit is coated with antibodies that are specific to the defect to be diagnosed. Standards/samples are later put on the plate as is appropriate. The samples or standards contain biotin-conjugate antibodies that are specific for the defect. Avidin conjugate is then added to every plate before incubating.

After putting substrate solutions together with other reagents, only the micro-wells will have Tropin I type three. A color change will then be exhibited, and a stopper solution is added. The change in color is then measured using wavelengths.
