| overlap hybridization | A procedure to find and sequence a gene whose approximate position in a chromosome is known by classical genetic linkage studies. Starting with the known sequence of a gene shown by classical genetics to be near to the novel gene, new clones are picked from a genomic library by hybridisation with a short probe generated from the appropriate end of the known sequence. The new clones are then sequenced, new probes generated and the process repeated until the gene of interest is reached. (18 Nov 1997) |
| fluorescence in situ hybridization | <molecular biology, technique> A type of in situ hybridization in which target sequences are stained with fluorescent dye so their location and size can be determined using fluorescence microscopy. This staining is sufficiently distinct that the hybridization signal can be seen both in metaphase spreads and in interphase nuclei. Acronym: FISH (25 Jun 1999) |
| fluorescent in situ hybridization | See FISH. (12 Dec 1998) |
| blot | 1. To spot, stain, or bespatter, as with ink. "The brief was writ and blotted all with gore." (Gascoigne) 2. To impair; to damage; to mar; to soil. "It blots thy beauty, as frosts do bite the meads." (Shak) 3. To stain with infamy; to disgrace. "Blot not thy innocence with guiltless blood." (Rowe) 4. To obliterate, as writing with ink; to cancel; to efface; generally with out; as, to blot out a word or a sentence. Often figuratively; as, to blot out offenses. "One act like this blots out a thousand crimes." (Dryden) 5. To obscure; to eclipse; to shadow. "He sung how earth blots the moon's gilded wane." (Cowley) 6. To dry, as writing, with blotting paper. Synonym: To obliterate, expunge, erase, efface, cancel, tarnish, disgrace, blur, sully, smear, smutch. Origin: Cf. Dan. Plette. See Blot. Source: Websters Dictionary (01 Mar 1998) |
| blot, northern | A technique in molecular biology, used mainly to separate and identify pieces of RNA. Called a Northern blot only because it is similar to a Southern blot (which is named after its inventor, the British biologist M.E. Southern). (12 Dec 1998) |
| blot, western | A technique in molecular biology, used to separate and identify proteins. Called a Western blot merely because it has some similarity to a Southern blot (which is named after its inventor, the British biologist M.E. Southern). (12 Dec 1998) |
| western blot | <technique> A technique similar to Southern blotting, though it is used for proteins. (09 Oct 1997) |
| Western blot analysis | A procedure in which proteins separated by electrophoresis in polyacrylamide gels are transferred (blotted) onto nitrocellulose or nylon membranes and identified by specific complexing with antibodies that are either pre-or post-tagged with a labelled secondary protein. See: immunoblot. Synonym: Western blot, Western blotting. Origin: coined to distinguish it from eponymic Southern blot a. (05 Mar 2000) |
| Northern blot | <molecular biology, procedure> An electroblotting method in which RNA is transferred to a filter and detected by hybridisation to (32)P labelled RNA or DNA. (18 Nov 1997) |
| Northern blot analysis | A procedure similar to the Southern blot analysis, used mostly to separate and identify RNA fragments; typically via transferring RNA fragments from an agarose gel to a nitrocellulose filter followed by detection with a suitable probe. Origin: coined to distinguish it from eponymic Southern blot a. (05 Mar 2000) |
| dot blot | <molecular biology, procedure> Method for detecting a specific protein or message. A spot of solution is dotted onto nitrocellulose paper, a specific antibody or probe is allowed to bind and the presence of bound antibody/probe then shown by using a peroxidase coupled second antibody, as in Western blotting or by other visualisation methods. (18 Nov 1997) |
| ink blot tests | Projective tests utilizing ink blots to which a subject responds. They are used in personality diagnosis. (12 Dec 1998) |
| zoo blot analysis | A procedure using Southern blot analysis to test the ability of a nucleic acid probe from one species to hybridise with the DNA fragment of another species. (05 Mar 2000) |
