Cytokine activity assay by means of proliferation measured in plane convex microtiter wells.
J Biochem Biophys Methods. 1996; 32(2):85-96
- Abstract:
- A new assay to measure cell proliferation by turbidimetric evaluation of cultures in specially designed microtiter plates was set up. The IL-2-dependent proliferation of CTLL-2 cell line was used as a model. The novel microtiter plate detection system, the General Cell Screening System (GCSS) was used for the evaluation of the cell proliferation assay. The test system utilizes the population growth rate (mu) of the cells. The tests were per-formed in specially designed microtiter plates which were read in a scanning spectrophotometer. These results were compared with colorimetric assays, using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium, inner salt (MTS) as substrates. In contrast to conventional methods. the presently described system is not an end-point method, this means that cell growth can be observed over a certain period and is not limited to a single moment during the period of cell growth. Another advantage is the reduction of manual manipulations and the avoidance of toxic or radioactive substances and organic solvents. Therefore, a higher number of samples can be analyzed compared to other methods. The range for detection was 0.015-10 units IL-2 per well, and the accuracy is in the range of < 0.005 standard deviation.
