Rist

rist - abbr. Radioimmunosorbent test. Variant of the International System of Units. For general use.

The word "RIST" contains seven letters. The first letter - "R" means Russian. The second letter - "I" means idea, intellect, less often individual in English. The third letter - "S" means signal. The fourth letter - "T" stands for technology, process, procedure. The fifth letter - "" means a space. The sixth letter is "." means dot. The seventh letter - "O" means ending.

Topic: History of the development of radioimmunosorbent RIST

RIST (radioimmunoabsorbent test) is one of the methods for determining antigen. This method is used to diagnose various diseases such as tuberculosis, cancer and other infectious diseases. RIST was developed in the 1950s. It is based on the use of antibodies - substances that can bind to certain proteins, so-called antigens.

An antibody that binds to an antigen is called an antiserum. Once the antiserum is mixed with a tissue or blood sample, it binds antigens. The sample is then introduced into a centrifuge to separate the antigens from the serum. The process of incubation or delivery of a radiocolloid label to the antigenic fraction is called a radionuclide test. The radiocolloid inside the sample turns it blue. Measuring the blue coloration of a sample helps identify the antigen. Once the sample is transferred to the filter, the filter is washed off and the presence of antiserum on the remaining sample is examined. RIST is currently used in laboratory research to detect a wide range of antigens. This is important because it helps medical researchers study the effects of environmental factors on the body. For example, the presence of antigens can help estimate the levels of alcohol in the air, pesticides, fertilizers, nitrates, insecticides and other harmful substances in the environment. In addition, genetic studies also use RIST to identify genetic markers such as clonal cells, lymphocytes, autoantibodies and immunologically related diseases
