Tetrahymena pyriformis is a species of single-celled ciliated protozoa that is commonly kept in laboratory cultures. It is a freshwater organism found in ponds, lakes, and rivers, and is the most studied species of its genus. It is widely used in research, due to its simplicity and its ability to rapidly reproduce. It is also used in a variety of educational settings, to teach students about cellular and molecular biology. T. pyriformis has a distinctive pear-shaped body and is approximately 10-20 micrometers in length. It is composed of a single cell with two nuclei, as well as numerous cilia that are used for movement. Additionally, the organism has specialized organelles such as contractile vacuoles that help to maintain osmotic pressure, and a cytostome that helps to ingest food. It is an omnivore, and will consume a variety of food sources, including bacteria and algae.

Tetrahymena pyriformis antigen is a type of protein found in the cell membranes of Tetrahymena pyriformis, a unicellular ciliated protozoan. This antigen has been the subject of scientific research for many years, and recent studies have revealed its potential uses in medicine.

Tetrahymena pyriformis antigen has a wide range of potential uses in medicine, including:

Immunology research: Tetrahymena pyriformis antigen is used as a tool for studying the immune response in humans and animals. It can be used to identify and isolate specific antibodies that are produced in response to various antigens.

Cancer research: Recent studies have shown that Tetrahymena pyriformis antigen has potential applications in cancer research. It has been shown to inhibit the growth of cancer cells in vitro, and further research is being conducted to investigate its potential as a cancer treatment.

Vaccine development: Tetrahymena pyriformis antigen has been used in the development of vaccines against a variety of diseases, including influenza and hepatitis B. It is used to stimulate the immune system and produce an immune response against the disease.

Tetrahymena pyriformis cDNA and recombinant antigens can be used in a variety of ways. They can be used to detect and identify specific pathogens, to develop assays for detecting and quantifying genetic markers, and to create novel vaccine candidates for the treatment of various diseases. In addition, these cDNAs and antigens can be used to study the biology of organisms, such as for gene expression studies and for the study of protein interactions. They can also be used for biotechnology applications, such as for production of recombinant proteins and for the development of diagnostic tests.

The use of recombinant proteins/cDNA in academic research and therapeutic applications has skyrocketed. However, in heterologous expression systems, successful recombinant protein expression is dependent on a variety of factors, including codon preference, RNA secondary structure, and GC content. When compared to pre-optimization, more and more experimental results demonstrated that the expression level was dramatically increased, ranging from two to hundred times depending on the gene. Bioclone has created a proprietary technology platform that has resulted in the creation of over 6,000 artificially synthesized codon-optimized cDNA clones (cloned in E. coli expression Vector), which are ready for production of the recombinant proteins.
