|---|---|
| gels | Colloids with a solid continuous phase and liquid as the dispersed phase; gels may be unstable when, due to temperature or other cause, the solid phase liquifies; the resulting colloid is called a sol. (12 Dec 1998) |

| gas-liquid chromatography | <technique> A chemistry lab technique, a type of column chromatography, used to separate the components of a mixed substance. The substance is held stationary by an inert solid coated with an inert liquid which is not likely to evaporate (i.e. Is nonvolatile), while a gas (called an eluant) flows past it bringing out the components one at a time. (09 Oct 1997) |
| Max | Transcription factor: forms homodimers which then interact with CACGTG motif of DNA repressively, but will form heterodimers with Myc that bind the same motif with greater affinity and activate the downstream gene. (18 Nov 1997) |
