| secretory component of IgA | <immunology, protein> A polypeptide chain of about 60 kD that aids secretion of the IgA, a portion of the IgA receptor on the plasmalemma of the inner side of the epithelial cells lining the gut, which is proteolysed when the IgA receptor complex has travelled through the cell after receptor mediated endocytosis at the inner face, to the outer (luminal) face.

| serum amyloid P component | Precursor of amyloid component P, found in basement membrane. Member of the pentraxin family. See: serum amyloid. (18 Nov 1997) |
| two-component plasma | <radiobiology> Refers to a plasma containing a cool thermal component and a population of high energy particles (such as from neutral beam injection) which are in the process of thermalising (slowing down). (09 Oct 1997) |
| acid-fast | <microbiology> A term used to denote bacteria that are not decolorised by acid-alcohol after having been stained with dyes such as basic fuchsin. The presence of acid fast organisms can be found in cultures that contain mycobacteria or some of the nocardiae. (12 Jul 2000) |
| acid-fast stain | <technique> A staining technique used to determine the cell wall property of a microorganism. After stained with dye such as hot carbolfuschin, an acid-fast organism, (for example Mycobacterium species) will retain the colour in its cell wall after being washed with acid-alcohol.

| serum-fast | 1. Pertaining to a serum in which there is little or no change in the titre of antibody, even under conditions of treatment or immunologic stimulation. 2. Resistant to the destructive effect of sera. Synonym: serofast. (05 Mar 2000) |
| spectrometry, mass, fast atom bombardment | A mass spectrometric technique that is used for the analysis of a wide range of biomolecules, such as glycoalkaloids, glycoproteins, polysaccharides, and peptides. Positive and negative fast atom bombardment spectra are recorded on a mass spectrometer fitted with an atom gun with xenon as the customary beam. The mass spectra obtained contain molecular weight recognition as well as sequence information. (12 Dec 1998) |
| sputum for acid-fast organisms | A special microscopic slide that is prepared to detect the presence of acid-fast bacilli. The diagnosis of tuberculosis can be made using this test. If the sputum specimen shows the acid fast organism a sputum culture (for Mycobacterium) is then performed. (27 Sep 1997) |
| drug-fast | Pertaining to microorganisms that resist or become tolerant to an antibacterial agent. (05 Mar 2000) |
