| gel retardation assay | A lab technique used to find out if there are proteins binding a fragment of DNA (in a DNA-protein complex) by watching how fast the DNA fragment moves through an electric field and seeing whether it moves slower when a particular protein is also present. (09 Oct 1997) |

| gel structure | Brush heap structure of fibrils giving firmness to hydrocolloids. (05 Mar 2000) |
| gel transfer | Any lab technique used to transfer substances which had been separated using gel electrophoresis from the gel to a membrane for further processing or analysis. For example: any type of blotting. (09 Oct 1997) |
| pharmacopeial gel | A suspension, in a water medium, of an insoluble drug in hydrated form wherein the particle size approaches or attains colloidal dimensions. (05 Mar 2000) |
| chromatography, gel | Chromatography on non-ionic gels without regard to the mechanism of solute discrimination. (12 Dec 1998) |
| colloidal gel | A colloid that has developed resistance to flow because of chemical or thermal change. (05 Mar 2000) |
| polyacrilamide gel | A white, water-soluble, solid gel used as a gel base for electrophoresisand as a thickening or adhesive additive in other industrialapplications. (09 Oct 1997) |
| polyacrylamide gel electrophoresis | Analytical and separative technique in which molecules, particularly proteins, are separated by their different electrophoretic mobilities in a hydrated gel. The gel suppresses convective mixing of the fluid phase through which the electrophoresis takes place and contributes molecular sieving. Commonly carried out in the presence of the anionic detergent sodium dodecylsulphate (SDS). SDS denatures proteins so that noncovalently associating sub unit polypeptides migrate independently and by binding to the proteins confers a net negative charge roughly proportional to the chain weight. See: SDS PAGE. (21 Jun 1999) |
| pulsed-field gel electrophoresis | Gel electrophoresis in which, after electrophoretic migration has begun, the current is briefly stopped and reapplied in a different orientation; allows for the purification of long DNA molecules. Synonym: pulsed-field gel electrophoresis. (05 Mar 2000) |
| pulse-field gel electrophoresis | Gel electrophoresis in which, after electrophoretic migration has begun, the current is briefly stopped and reapplied in a different orientation; allows for the purification of long DNA molecules. Synonym: pulsed-field gel electrophoresis. (05 Mar 2000) |
| sol gel transformation | Transition between more fluid cytoplasm (endoplasm) and stiffer gel like ectoplasm proposed as a mechanism for amoeboid locomotion: since the endoplasm cannot really be considered a simple fluid and has visco elastic properties like a gel, the term is misleading. (18 Nov 1997) |
| disc gel | Confusingly, nothing to do with shape, gels in which there is a discontinuity in pH or gel concentration or buffer composition. (18 Nov 1997) |
| electrophoresis, agar gel | Electrophoresis in which agar or agarose gel is used as the diffusion medium. (12 Dec 1998) |
| electrophoresis, gel, pulsed-field | Electrophoresis in which the direction of the electric field is changed periodically. This technique is similar to other electrophoretic methods normally used to separate double-stranded DNA molecules ranging in size up to tens of thousands of base-pairs. However, by alternating the electric field direction one is able to separate DNA molecules up to several million base-pairs in length. (12 Dec 1998) |
| electrophoresis, gel, two-dimensional | Electrophoresis in which a second perpendicular electrophoretic transport is performed on the separate components resulting from the first electrophoresis. This technique is usually performed on polyacrylamide gels. (12 Dec 1998) |
