| gel filtration | <molecular biology> An important method for separating molecules according to molecular size by percolating the solution through beads of solvent permeated polymer that has pores of similar size to the solvent molecules. Unlike a continous filter that retards flow according to molecular size, separation is achieved because molecules that can enter the beads take a longer path (i.e. Are retarded) than those that cannot. Typical gels for protein separation are made from polyacrylamide or from flexible (Sephadex) or rigid (agarose, Sepharose) sugar polymers. The size separation range is determined by the degree of cross linking of the gel. (05 May 1997) |

| glomerular filtration rate | <nephrology> Measure of the kidneys' ability to filter and remove waste products. (09 Oct 1997) |
| filtration | The passage of a liquid through a filter, accomplished by gravity, pressure or vacuum (suction). (18 Nov 1997) |
| filtration angle | The acute angle between the iris and the cornea at the periphery of the anterior chamber of the eye. Synonym: angulus iridocornealis, angle of iris, angulus iridis, filtration angle. (05 Mar 2000) |
| filtration coefficient | A measure of a membrane's permeability to water; specifically, the volume of fluid filtered in unit time through a unit area of membrane per unit pressure difference, taking into account both hydraulic and osmotic pressures. (05 Mar 2000) |
| filtration fraction | The fraction of the plasma entering the kidney that filters into the lumen of the renal tubules, determined by dividing the glomerular filtration rate by the renal plasma flow; normally, it is around 0.17. (05 Mar 2000) |
| filtration slits | The intercellular clefts between the interdigitating pedicels of podocytes; they are part of the filtration barrier of renal corpuscles. Synonym: filtration slits. (05 Mar 2000) |

| biological | Pertaining to biology. (18 Nov 1997) |
| biological agent | <microbiology> A disease-causing microorganism or virus, or other toxic biological matter, which is used as a weapon during war. (21 Mar 1998) |
| biological assay | <technique> Once a pharmaceutical protein is isolated from the cells in which it was grown, researchers perform tests to measure the protein's biological activity. It must maintain a certain minimal level of biological activity to be used for animal or clinical testing or, later, for market. Researchers also test to confirm that the isolated protein is identical to the desired protein. (21 Mar 1998) |
| biological assessment | A specific process required as part of an environmental assessment. An evaluation of potential effects of a proposed project on proposed, endangered, threatened, and sensitive animal and plant species and their habitats. (05 Dec 1998) |
| biological availability | The extent to which the active ingredient of a drug dosage form becomes available at the site of drug action or in a biological medium believed to reflect accessibility to a site of action. (12 Dec 1998) |
| biological chemistry | The scientific study of the chemistry of living cells, tissues, organs and organisms. (09 Oct 1997) |
