Abstract

Detection of cellular response by measuring intracellular calcium, (Ca2+)i with Ca2+-dependent fluorescent dye are standard approaches to detect ligand-stimulated cells and to study signaling through ligand/receptor interaction. We describe a single-cell microarray system to analyze cellular response of individual cells such as lymphocytes using microchamber array chips. The single-cell microarray chip is made from polystyrene with over 30,000 microchambers, which can accommodate only single cells. Lymphocytes derived from mouse spleen or human blood were spread on the microarray, and over 80% of the microchambers achieved single-cell status. Stimulation of B-cells through antigen receptors on the microarray allowed us to detect activated B-cells by comparing the states of single B-cells before and after stimulation with antigen, which is disabled for flow cytometry. In addition, this novel method demonstrated retrieval of positive single B-cells from microchambers by a micromanipulator and achieved antibody DNA analysis. The system is suitable for high-throughput analysis of intracellular Ca2+ response at the single-cell level and is applicable to screen antigen-specific lymphocytes for making specific monoclonal antibody.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
