Receptor: 1. In cell biology, a structure on the surface of a cell (or inside a cell) that selectively receives and binds a specific substance. There are many receptors.
The most common is EPNS (Electro Plated Nickel Silver) but many other symbols are used: 1  EPBM (Electro Plated Britannia Metal). 2  EPCA (Electro Plated Copper Alloy). 3  ESM (Electro Plated Silver Mounts).he most common is EPNS (Electro Plated Nickel Silver) but many other symbols are used: 1  EPBM (Electro Plated Britannia Metal). 2  EPCA (Electro Plated Copper Alloy). 3  ESM (Electro Plated Silver Mounts).
EPO (erythropoietin). Erythropoietin is a glycoprotein that is produced by the kidneys and is commonly referred to as EPO. EPO is responsible for red blood cell production; the red blood cells are responsible for carrying oxygen to and through the blood.While the human body naturally produces EPO, thanks to recombinant DNA technology we now have exogenous EPO known as Epoetin Alfa.he side effects of EPO can actually be far worse than the use of anabolic steroids as the risk of death does exist. Management in a medical setting will rarely lead to this outcome, but high levels of EPO can be problematic.
