| fluorescent antibody technique | Test for tissue antigen using either a direct method, by conjugation of antibody with fluorescent dye (fluorescent antibody technique, direct) or an indirect method, by formation of antigen-antibody complex which is then labelled with fluorescein-conjugated anti-immunoglobulin antibody (fluorescent antibody technique, indirect). The tissue is then examined by fluorescence microscopy. (12 Dec 1998) |
| fluorescent antibody technique, direct | A form of fluorescent antibody technique utilizing a fluorochrome conjugated to an antibody, which is added directly to a tissue or cell suspension for the detection of a specific antigen. (12 Dec 1998) |
| fluorescent antibody technique, indirect | A form of fluorescent antibody technique commonly used to detect serum antibodies and immune complexes in tissues and microorganisms in specimens from patients with infectious diseases. The technique involves formation of an antigen-antibody complex which is labelled with fluorescein-conjugated anti-immunoglobulin antibody. (12 Dec 1998) |
| flush technique | <procedure> A technique for determining the systolic blood pressure in infants; the elevated limb is milked of blood from the hand or foot proximally; the blood pressure cuff is then inflated above the likely systolic pressure and the limb lowered; the cuff pressure is then gradually released until the blanched limb flushes. (05 Mar 2000) |
| long cone technique | The use of a cone distance of 14 inches or more in making oral roentgenographs. (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) |
