||This antibody needs to be stored at + 4°C in a fridge short term in a concentrated dilution. Freeze thaw will destroy a percentage in every cycle and should be avoided.Antibody for research use.this 1 cDNA is double stranded complementary DNA derived by genways from mRNA with very high fidelity reverse transcription using a pfu or pfx mix,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.Human proteins from Homo sapiens human species. Homo is the human genus, which also includes Neanderthals and many other extinct species of hominids. Specific human epitopes are selected for human ELISA kits.
