| 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.

| 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.

| group transfer | The transfer of a functional moiety from one molecule to another. (05 Mar 2000) |
| phospholipid transfer protein | <protein> Cytoplasmic proteins that bind phospholipids and facilitate their transfer between cellular membranes. May also cause net transfer from the site of synthesis. (18 Nov 1997) |
| modulation transfer function | <microscopy> A mathematical function that expresses the ability of an optical or electronic device to transfer signals faithfully as a function of the spatial or temporal frequency of the signal. The modulation transfer function is the ratio of percentage modulation of a sinusoidal signal leaving to that entering the device over the range of frequencies of interest. The modulation transfer function is usually presented as a graph of modulation transfer function versus log (frequency). For a square wave signal, the function is known as the CTF. Acronym: MTF (26 Mar 1998) |

| cotranslational transfer | <cell biology, molecular biology> Putting the leading end of a polypeptide into the membrane of the endoplasmic reticulum before translation of the rest of the polypeptide has been finished. (10 Nov 1998) |
| heat transfer efficiency | Useful heat output released to the room divided by the actual heat produced in the firebox (17 Dec 1998) |
