Aplha, transcription related growth factors and stimulating factors or repressing nuclear factors are complex subunits of proteins involved in cell differentiation
Complex subunit associated factors are involved in hybridoma growth, Eosinohils, eritroid proliferation and derived from promotor binding stimulating subunits on the DNA binding complex
NFKB 105 subunit for example is a polypetide gene enhancer of genes in B cells.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, 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.
