| cells, immobilised | Microbial, plant, or animal cells which are immobilised by attachment to solid structures, usually a column matrix. A common use of immobilised cells is in biotechnology for the bioconversion of a substrate to a particular product. (12 Dec 1998) |
|---|
| co-immobilised enzyme | <biochemistry> A group of enzymes which work together and are physically confined while doing so. (09 Oct 1997) |
|---|---|
| immobilised cell bioreactors | Bioreactors in which the cells grown are immobilised onto some sort of support material. (14 Nov 1997) |
| immobilised cell biosensor | Biosensors that use living cells as an essential part of their detector system. The immobilised cell does the sensing and produces a very weak signal of some sort, which is detected and amplified into a signal the user can read. (14 Nov 1997) |
| immobilised enzyme | <biochemistry> An enzyme attached to a solid support over which substrate is passed and is converted into product. (09 Oct 1997) |
| enzymes, immobilised | Enzymes which are immobilised on or in a variety of water-soluble or water-insoluble matrices with little or no loss of their catalytic activity. Since they can be reused continuously, immobilised enzymes have found wide application in the industrial, medical and research fields. (12 Dec 1998) |
| absorptive cells of intestine | Cell's on the surface of villi of the small intestine and the luminal surface of the large intestine that are characterised by having microvilli on their free surface. (05 Mar 2000) |
| air cells | Air-containing spaces in the skull. See: pulmonary alveolus. (05 Mar 2000) |
| air cells of auditory tube | Occasional small air cells in the inferior wall of the auditory tube, near the tympanic orifice, communicating with the tympanic cavity. Synonym: cellulae pneumaticae tubae auditivae, air cells of auditory tube. (05 Mar 2000) |
| Alpha cells | Alpha cell's of pancreas or of anterior lobe of hypophysis. (05 Mar 2000) |
| alpha cells of anterior lobe of hypophysis | Acidophil cell's that constitute about 35% of the cell's of the anterior lobe. There are two varieties: one that elaborates somatotropin, another that elaborates prolactin. (05 Mar 2000) |
| alpha cells of pancreas | Cell's of the islets of Langerhans that secrete glucagon. (05 Mar 2000) |
| amniogenic cells | Cell's from which the amnion develops. (05 Mar 2000) |
| anabiotic cells | Cell's that are capable of resuscitation after apparent death; the existence of anabiotic tumour cell's is postulated to explain the recurrence of a cancer after a very long symptomless period following operation. (05 Mar 2000) |
| angioblastic cells | Those cell's in the early embryo from which primitive blood cell's and endothelium develop. (05 Mar 2000) |
| anterior cells | The anterior group of air cells of the ethmoidal sinus's; each sinus communicates with the middle meatus of the nasal cavity. Synonym: sinus ethmoidales anteriores, anterior cells, anterior sinuses, cellulae anteriores. (05 Mar 2000) |
