Magnetic separation techniques in diagnostic microbiology.
The principles of magnetic separation aided by antibodies or other specific binding molecules have been used for isolation of specific viable whole organisms, antigens, or nucleic acids. Whereas growth on selective media may be helpful in isolation of a certain bacterial species, immunomagnetic separation (IMS) technology can isolate strains possessing specific and characteristic surface antige...
متن کاملImmunofluorescence techniques.
anTiBOdies An antibody is a protein complex produced by B cells that initiates an immune response against a target antigen. The basic organization of an antibody includes two functional domains that, together, resemble the letter Y (Figure 1, left). The Fab (fragment having the antigen binding site) domain makes up the arms of the Y, and at the end of each arm is a variable region responsible f...
متن کاملDiagnostic virology laboratory within a microbiology setting.
The virology section at St. Francis Hospital and Medical Center, Connecticut, is not a separate laboratory division but is a part of the microbiology division and is supervised by the same personnel who supervise bacteriology, mycology, mycobacteriology, and serology. Current volume is over 1,000 cultures yearly with 12 to 24 percent positive. Isolates are confirmed and typed by the Connecticut...
متن کاملTechniques of immunofluorescence and their significance.
1) Skin or mucosal biopsy specimens are usually obtained by 3-5 mm punch or surgical biopsy. 2) Biopsy specimens are snap frozen. If there is a delay between biopsy and snap freezing, the specimen should be kept in cold saline. 3) Frozen 4-6μ sections are cut on a cryostat and placed on a glass slide before being air-dried for 15 minutes. 4) After rinsing in phosphate buffered saline (PBS), pH ...
متن کاملEnhanced diagnostic immunofluorescence using biopsies transported in saline
BACKGROUND The demonstration of tissue-bound immunoreactants by direct immunofluorescence microscopy (DIF) is a valuable parameter in the diagnosis of various autoimmune and immunecomplex-mediated skin diseases. For preservation of tissue-bound immunoreactants, biopsies are usually fresh-frozen in liquid nitrogen or transported in Michel's fixative. But even optimally preserved tissue specimens...
