| basic salt | A salt in which there are one or more hydroxyl ions not replaced by the electronegative element of an acid; e.g., Fe(OH)2Cl. (05 Mar 2000) |
|---|---|
| basic stain | <technique> A dye in which the cation is the coloured component of the dye molecule that binds to anionic groups of nucleic acids (PO4≡) or acidic mucopolysaccharides (e.g., chondroitin sulfate). (05 Mar 2000) |
| platelet basic protein | <protein> Protein that is the precursor of connective tissue activating peptide III and _ thromboglobulin. (18 Nov 1997) |
| myelin basic protein | <protein> Major component of the myelin sheath in mammalian CNS. Used as an antigen will induce a allergic encephalitis, possibly a model for some neurodegenerative disorders. (18 Nov 1997) |
| myelin basic protein kinase | <enzyme> Protein from pig brain activates ATP-mg-dependent protein phosphatase; a protein tau kinase; a multisubstrate kinase; in texts written as f subscript a Registry number: EC 2.7.1.- Synonym: protein phosphatase activator fa, glycogen synthase kinase 3, protein kinase f(a), gsk-3, gsk-3alpha, kinase f(a), gsk-3beta, mds1 gene product, p63(samk), src-activated mbp kinase, p63(mapk) (26 Jun 1999) |
| myelin basic proteins | A group of 7 proteins produced from a single gene by alternate splicing found in central and peripheral nervous system myelin. The major basic protein (mbp) has long been of interest because it is the antigen, that, when injected into an animal, elicits a cellular immune response that produces the CNS autoimmune disease called experimental allergic encephalomyelitis (encephalomyelitis, allergic). In the peripheral nervous system, myelin basic protein 18.5 kD is often referred to as the p1 protein. (12 Dec 1998) |
| haematoxylin-malachite green-basic fuchsin stain | <technique> A stain for epoxy resin-extracted sections; semi-thick sections have their plastic dissolved out and the residual tissue is stained sequentially with the various dyes; nuclei and astrocytes are purplish-pink and myelin, lipid droplets, nucleoli, and oligodendrocytes are bright blue-green. (05 Mar 2000) |
| fibroblast growth factor, basic | A single-chain polypeptide of approximately 15-16 kD which has been isolated from a variety of cells. It has a 55% amino acid residue identity to acidic fibroblast growth factor and has potent heparin-binding activity. However, in contrast to the acidic fibroblast growth factor, heparin does not potentiate the biological activities of bfgf. The growth factor is an extremely potent inducer of DNA synthesis in a variety of normal diploid mammalian cell types from mesoderm and neuroectoderm lineages and promotes cellular differentiation in vitro. (12 Dec 1998) |
| age factors | Age as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or the effect of a circumstance. It is used with human or animal concepts but should be differentiated from aging, a physiological process, and time factors which refers only to the passage of time. (12 Dec 1998) |
| bacteriocin factors | Bacterial plasmid's responsible for the elaboration of bacteriocins. Synonym: bacteriocin factors, bacteriocinogens. (05 Mar 2000) |
| B-cell differentiation/growth factors | Various substances, usually obtained from the supernatant of T-cell cultures, such as interleukin 4, 5, and 6. These substances are necessary for B-cell growth, maturation, and differentiation into plasma cells or B memory cells. (05 Mar 2000) |
| biological factors | Compounds made by living organisms. They have biological or physiological activities. (12 Dec 1998) |
| biotic factors | Environmental factor's or influences resulting from the activities of living organisms, as contrasted to those resulting from climatic, geological, or other factor's. (05 Mar 2000) |
| blood coagulation factors | Endogenous substances, usually proteins, that participate in the blood coagulation process. (12 Dec 1998) |
| macrophage migration-inhibitory factors | Proteins released by sensitised lymphocytes and possibly other cells that inhibit the migration of macrophages away from the release site. The structure and chemical properties may vary with the species and type of releasing cell. (12 Dec 1998) |
