| Abstract |
This article presents a real-time monitoring system for cellular analysis using micro total analysis systems technology. Time-resolved luminescence anisotropy analysis was adopted for real-time detection of small amounts of a target protein produced by a small number of cells. The system was tested by real-time monitoring of the antibody secretion by hybridomas. The cells were successfully cultivated in a micro-incubation chamber (240 nl) fabricated on a microchip. The quantification of the antibody was achieved using the Ru(II) complex-labeled Staphylococcus aureus protein A probe, which can bind specifically to the Fc region of the antibody. Using this system, we detected as little as 24 fmol of immunoglobulin G under physiological conditions without the bound/free separation protocol. We successfully achieved real-time and quantitative monitoring of small amounts of antibody production by approximately 200 hybridoma cells. This method could be applied to various cellular analyses using small numbers of cells. |
