| genes, reporter | Genes whose expression is easily detectable and therefore used to study promoter activity at many positions in a target genome. In recombinant DNA technology, these genes may be attached to a promoter region of interest. (12 Dec 1998) |
|---|---|
| reporter gene | <molecular biology> A gene that encodes an easily assayed product (e.g. CAT) that is coupled to the upstream sequence of another gene and transfected into cells. The reporter gene can then be used to see which factors activate response elements in the upstream region of the gene of interest. (18 Nov 1997) |
| PAS | <abbreviation> P-aminosalicylic acid; periodic acid-Schiff stain. (05 Mar 2000) |
| PAS gene | <genetics, molecular biology> Genes essential for the biogenesis and proliferation of peroxisomes in yeast (s. Cerevisiae). PAS1 codes for a rather hydrophilic 117 kD protein with two ATP binding sites and similarity with some ATPases, PAS2 codes for a 183 residue polypeptide that seems to be a member of the ubiquitin conjugating protein family, PAS3 codes for a 48 kD integral membrane protein that may be part of the import machinery. (18 Nov 1997) |
| PAS stain | <technique> A histochemical technique based on periodic acid oxidation of a substance containing the 1,2-glycol grouping. It is used for staining carbohydrates as the resulting dialdehyde reacts with Schiff reagent to form a coloured product. Substances that can be demonstrated include carbohydrates, mucins, cartilage matrix, collagen, reticulum, basement membranes, fibrin, thyroid colloid, amyloid, glomerular hyaline deposits, and a number of other secretions or tissue constituents. Also used in for staining gels on which glycoproteins have been run. See: periodic acid Schiff reaction Synonym: PAS stain. (22 Sep 2002) |
| Kasten's fluorescent PAS stain | <technique> A fluorescent modification of the periodic acid Schiff stain for polysaccharides which uses one of Kasten's fluorescent Schiff reagents. (05 Mar 2000) |
