Additional description
Guinea pig ELISA kits for plasma and sera samples are used to study human genes through the guinea pig model (Cavia porcellus), also called the cavy rodent model. After mouzes and rats Guinea pigs are easy in maintained laboratory animals. cDNAs of Guinea pigs are also very popular.Associated membrane protein types are lipopolysaccharide selective barriers. Biological membranes include cell membranes, outer coverings of cells or organelles that allow passage of certain proteins and nuclear membranes, which cover a cell nucleus; and tissue membranes, such as mucosae and serosae. ,The receptors are ligand binding factors of type 1, 2 or 3 and protein-molecules that receive chemical-signals from outside a cell. When such chemical-signals couple or bind to a receptor, they cause some form of cellular/tissue-response, e.g. a change in the electrical-activity of a cell. In this sense, am olfactory receptor is a protein-molecule that recognizes and responds to endogenous-chemical signals, chemokinesor cytokines e.g. an acetylcholine-receptor recognizes and responds to its endogenous-ligand, acetylcholine. However, sometimes in pharmacology, the term is also used to include other proteins that are drug-targets, such as enzymes, transporters and ion-channels.
