Molecular biology
Energy balance
Biology; Biochemistry
The thermodynamic necessity that for any organism, the energy intake (nutrients, light for photosynthesis, etc.) must equal the internal heat produced, the work (movement, transport, etc.) and growth ...
Immunofluorescence
Biology; Biochemistry
The visualisation of an antigen in a histological section or on a polyacrylamide slab by allowing it to combine with a fluorophore-tagged antibody. In indirect immunofluorescence the antibody is not ...
Transduction
Biology; Biochemistry
The conversion of one kind of energy into another, e.g. conversion of the chemical energy of ATP into mechanical energy by muscle contraction; also conversion of a signal as it crosses a barrier, ...
Scaffold protein
Biology; Biochemistry
One of the non-enzymic components of a multi- protein signal transduction complex. The complex is assembled upon activation of the receptor or is assembled but dormant until receptor activation. The ...
Cyclophilin
Biology; Biochemistry
An enzyme that binds the immunosuppressant compound cyclosporin, thereby blocking its activity as a peptidylprolyl cis¿trans isomerase. Cyclophilin A is present in the cytosol and when bound to ...
Protein nucleic acid (PNA)
Biology; Biochemistry
A polyamide backbone, e.g. (-NH-CH 2 -CH 2 -NR-CH 2 -CO-) n , which bears purine and pyrimidine bases (R in the formulation) and can mimic oligonucleotides by hybridising with ssDNA or RNA. Some PNAs ...
Surface plasmon resonance (SPR)
Biology; Biochemistry
An optical technique for the detection and quantification of binding which has been incorporated into some biosensors. The material to which binding will be detected is immobilised on the surface of ...
