The reform legislature passed the Stetson-Eshelman Act, which increased the state Railroad Commissionâs authority and power to fix passenger and freight rates; thus ending Southern Pacific Railroadâs (SP) crushing monopolistic practices.
Each antibody binds to a specific antigen; an interaction similar to a lock and key. An antibody (Ab), also known as an immunoglobulin (Ig), is a large, Y-shaped protein produced mainly by plasma cells that is used by the immune system to identify and neutralize pathogens such as bacteria and viruses.
Antibodies are small proteins that circulate in the bloodstream. They are part of the body's defence (immune) system and are sometimes called immunoglobulins. They are made by a type of white blood cell (a B lymphocyte). Antibodies attach to proteins and other chemicals in the body, which they recognise to be not normally found in the body ('foreign'). The foreign proteins and chemicals that antibodies attach to are called antigens.
