Antibodies Research proteins and antibodies: Antibodies Antibodies are proteins that circulate in the blood and the lymph. They are central constituents of the immune system. The immune system defends the body from attack by infectious agents: viruses, bacteria, parasites and fungi. It also protects against foreign, damaged, pre-cancerous and cancerous cells. The immune system must distinguish between self and non-self and inactivate, remove or destroy any non-self substances. Immune system The immune system is distributed throughout the body’s lymphoid organs. The bone marrow and thymus are the primary lymphoid organs. The cells of the immune system are produced along with red blood cells and platelets from stem cells in the bone marrow. Immature T-cells are matured in the thymus, a gland in the chest. The secondary lymphoid organs are the spleen, appendix, tonsils, adenoids and lymph nodes. They contain reservoirs of immune cells so that any antigens in blood or lymph passing through the secondary lymphoid organs are exposed to the cells of the immune system.

recombinant proteins Research proteins and antibodies: recombinant proteins A protein is a chain of amino acids encoded by DNA and folded to produce a three-dimensional structure. Proteins are structural components of the cell and participate in all cellular and physiological functions. Protein production The DNA sequence is transcribed to produce nascent messenger RNA (mRNA). The mRNA is transported out of the cell nucleus into the cytoplasm for translation into protein. The mRNA sequence is used as a template to construct a protein in the ribosome. This process is called translation. The ribosome interprets the mRNA sequence by reading its nucleotides in sets of three, called codons. The specific sequence of the three nucleotides in a codon corresponds to one amino acid. The ribosome reads the mRNA codons and adds the correct amino acid to the growing chain. The amino acid sequence of a protein is referred to as its primary structure. mRNA may be used repeatedly to produce several proteins, however it is rapidly broken down by ribonucleases.
