| fluorescence microscopy | <procedure> Any type of microscopy in which intrinsic or applied reagents are visualised. Intrinsic fluorescence is often referred to as auto fluorescence. The applied reagents typically include fluorescently labelled proteins that are reactive with sites in the specimen. In particular, fluorescently labelled antibodies are widely used to detect particular antigens in biological specimens. (18 Nov 1997) |

| fluorescence plus Giemsa stain | <technique> A stain used to demonstrate sister chromatid exchange; cells are grown in 5-bromodeoxyuridine, followed by chromosome preparation, staining in Hoechst 33258, exposure to light, and staining in Giemsa; chromosomes exhibit a "harlequin" appearance. (05 Mar 2000) |
| fluorescence polarization | Measurement of the polarization of fluorescent light from solutions or microscopic specimens. It is used to provide information concerning molecular size, shape, and conformation, molecular anisotropy, electronic energy transfer, molecular interaction, including dye and coenzyme binding, and the antigen-antibody reaction. (12 Dec 1998) |
| fluorescence recovery after photobleaching | Many fluorochromes are bleached by exposure to exciting light. If, for example: the cell surface is labelled with a fluorescent probe and an area bleached by laser illumination, then the bleached patch that starts off as a dark area will gradually recover fluorescence. The recovery is due to the re population of the area by unbleached molecules and diffusion of bleached molecules to other areas. The rate and extent of recovery are a measure of the fluidity of the membrane and the proportion of labelled molecules that are free to exchange with adjacent areas. The technique is usually applied to cell surface fluidity or viscosity measurements, but is also applicable to other structures. (18 Nov 1997) |
| fluorescence spectrum | Fluorescence evoked over a range of wavelengths when the excitation wavelength is at a maximum. (05 Mar 2000) |
| adoptive transfer | Form of passive immunization where previously sensitised immunologic agents (cells or serum) are transferred to non-immune recipients. When transfer of cells is used as a therapy for the treatment of neoplasms, it is called adoptive immunotherapy (immunotherapy, adoptive). (12 Dec 1998) |
| gamete intra-fallopian transfer | <gynaecology> Gamete intra-fallopian transfer is a technique that involves combining eggs and sperm outside of the body and immediately placing them into the fallopian tubes to achieve fertilization. A technique that came into use in the mid-1980's for assisted conception in infertile women with normal fallopian tubes. The protocol consists of hormonal stimulation of the ovaries, followed by laparoscopic follicular aspiration of oocytes, and then the transfer of sperm and oocytes by catheterization into the fallopian tubes. Acronym: GIFT (12 Dec 1998) |
| 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) |
| gene transfer | <molecular biology> General tem for the insertion of foreign genes into a cell or organism. Synonymous with transfection. (18 Nov 1997) |
| cavernous transfer of portal vein | <anatomy, vein> Replacement of the portal vein by a number of collateral channels, a consequence of thrombosis. (05 Mar 2000) |
| patient transfer | Interfacility or intrahospital transfer of patients. Intrahospital transfer is usually to obtain a specific kind of care and interfacility transfer is usually for economic reasons as well as type of care provided. (12 Dec 1998) |
| resistance-transfer factor | The transfer gene of the resistance plasmid. (05 Mar 2000) |
| resonance energy transfer | <technique> Transfer of energy from one fluorochrome to another. The emission wavelength of the fluorochrome excited by the incident light must approximately match the excitation wavelength of the second fluorochrome. If light at the second emission wavelength is detected, it implies that the two fluorochromes were physically within a few nanometres. Used as a technique to probe protein or cell interactions. (25 Jun 1999) |
| charge transfer | A complex between two organic molecules in which an electron from one (the donor) is transferred to the other (the acceptor), becoming generally distributed throughout the latter; subsequent transfer of a hydrogen atom completes the reduction of the acceptor; such complex's are generally highly coloured and may be so observed, a network of hydrogen bridges at the catalytic centre of certain proteases. Synonym: charge transfer system. (05 Mar 2000) |
| charge transfer complex | A complex between two organic molecules in which an electron from one (the donor) is transferred to the other (the acceptor), becoming generally distributed throughout the latter; subsequent transfer of a hydrogen atom completes the reduction of the acceptor; such complex's are generally highly coloured and may be so observed, a network of hydrogen bridges at the catalytic centre of certain proteases. Synonym: charge transfer system. (05 Mar 2000) |
