Biochemistry

Descriptive of killer T-cells that recognise and respond to a cell- surface marker on a T-cell that is actively secreting immunoglobulin; contrasted with anti-idiotypic, descriptive of killer T-cells ...

GABA shunt

Biology; Biochemistry

An alternative route from α-oxoglutarate to succinyl-CoA as part of the tricarboxylic acid cycle. Rather than going through the α-oxoglutarate dehydrogenase reaction, Â¿-oxoglutarate condenses with ...

STAT (signal transducer and activator of transcription)

Biology; Biochemistry

One of a family of proteins that mediate the actions of cytokines and growth factors. When the cytokine or growth factor receptor is occupied, a tyrosine residue of the STAT is phosphorylated and the ...

Pulsed amperimetric detection (PAD)

Biology; Biochemistry

A method for detection of chromatographic eluates, especially oligosaccharides, not easily detected by other means; a cycle of less than 1s first applies a voltage across the eluate, adsorbs the ...

Quantitative PCR (QPCR)

Biology; Biochemistry

A method for quantification of a polynucleotide by inclusion with it of a known amount of an easily distinguished template as an internal standard to compensate for variation in efficiency of ...

Mn2+ quench method

Biology; Biochemistry

A method for observation of the control of bivalent cation flux across the plasma membrane of a cell. Mn 2+ is used in place of Ca 2+ because, unlike Ca 2+ , it does not accumulate in intracellular ...

Simulated annealing

Biology; Biochemistry

An energy minimization technique to refine a model structure, e.g. an X-ray crystallographic or nuclear magnetic resonance model, by simulation of heating it to a high temperature to break all ...
