The antagonist receptor ligand binding will be in contrast with agonist activity
bioassay produces more antagonist and receptor related products as 1.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.
Properties
Human proteins, cDNA and human recombinants are used in human reactive ELISA kits and to produce anti-human mono and polyclonal antibodies
Modern humans (Homo sapiens, primarily ssp. Homo sapiens sapiens)
Depending on the epitopes used human ELISA kits can be cross reactive to many other species
Mainly analyzed are human serum, plasma, urine, saliva, human cell culture supernatants and biological samples.
Sample Types
serum, blood, plasma, saliva, urine, and other related tissue liquid
