Hotting-up the complement-fixation test

Detection of rotavirus by Latex Agglutination Test (Rotales); Comparison with Electron Microscopy and Complement Fixation Test

Quantitative micro-complement fixation test.

A quantitative micro-complement fixation test capable of detecting nanogram quantities of antigen is described. The test is simple to perform and is highly reproducible. Typical results from three antigen-antibody systems are given.

Evaluation of the gonococcal complement-fixation test.

The gonococcal complement-fixation test (GCFT), based on the same principle as the Wassermann reaction (WR), has been in use for over 60 years. The test was applied for the first time, using a culture of the gonococcus as antigen, by Muller and Oppenheim (1906) to establish the diagnosis in a case of arthritis. Teague and Torrey (1907) suggested that negative results in the GCFT were due to dif...

Brown fat - hotting up again.

For a decade or so from the late 1970s brown adipose tissue was a key focus of obesity research. The concept that adaptive changes in energy expenditure are important in the regulation of energy balance, with reductions in thermogenesis as a major factor in the development of obesity, had taken centre stage. This was based on some pivotal observations from studies on experimental animals. Brown...
