quadrapole mass filter

Biology; Biochemistry

The instrumentation for mass spectroscopy that allows selection of ions of a specific m/e - ratio. As the desorbed material travels down an electric field toward the detector, it passes through a ...

A method for identification of mRNAs produced under specific physiological conditions. Total cellular RNA is reverse-transcribed, and the resultant cDNAs are used as templates for PCR. The 3'-primer ...

cyclic amplification and selection of targets (CASTing)

Biology; Biochemistry

Essentially identical to the selected and amplified (protein) binding site oligonucleotide (SAAB) and target detection assay (TDA) procedures; a procedure for identification of consensus sequences of ...

protein splicing

Biology; Biochemistry

The excision of an intervening protein sequence, an intein, from a precursor protein, with peptide bond formation between the flanking domains (the N-extein, originally attached to the N-terminal end ...

synthetic peptide combinatorial library (SPCL)

Biology; Biochemistry

A strategy for determination of the specificity of a soluble peptide. Random collections of all the possible oligopeptides of a certain length, preceded by all the possible dipeptide sequences, are ...

thermogenesis model

Biology; Biochemistry

A theory of the origin of life, particularly of how prebiotic structures utilized environmental energy to drive synthetic processes. Basing itself on the current belief that the most primitive ...

atomic absorption spectrometry (AA)

Biology; Biochemistry

A method for quantifying elements, usually metals, in biological samples. The method depends upon the absorption of energy by atoms as they are excited in their electronic ground state. The choice of ...
