1. Gel
* A substance like jelly which consists of a liquid colloidally suspended in a solid. * To form such a substance.

2. Gel exclusion chromatography
A lab technique; a type of column chromatography , used to separate the components of a mixture by molecular size and to collect the molecules which are larger than a certain size. It is similar to gel filtration ; small molecules are slowed or trapped by the pores in the gel beads filling the column, while large molecules, too large to fit into the pores, slide past the beads and get to the bottom of the column first. At this point, the large molecules are collected. "Gel exclusion" refers to the maximum size of molecule which will fit into the gel bead pores, and this lab technique is used to collect the molecules in the mixture which are larger than, or "excluded" from, the pores.

3. Gel filtration
A type of chromatography that separates protein s in solution by running the solution containing the proteins through a column filled with porous carbohydrate gel beads which will trap or slow down small molecules but will allow larger molecules to slide past.

4. Gel retardation assay
A lab technique used to find out if there are protein s 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.

5. 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 .
