Abstract: We describe herein a cell-based multiplexing technique called detectable cell barcoding (DCB). In DCB, each individual sample is labeled with a different DCB signature that distinguishes each sample by one or both of detected intensity or type of detection characteristic. The samples are then combined and analyzed for a detectable characteristic of interest (e.g., presence of an analyte). By employing multiple distinct DCB labels at varying concentrations, one can perform multiplex analyses on up to hundreds or thousands (or more) of cell samples in a single reaction tube. DCB reduces reagent consumption by factors of 100-fold or more, significantly reduces data acquisition times and allows for stringent control sample analysis.

Abstract: In accordance with the present invention, it has been discovered that introduction of hydrophilic sulfoalkyl substituents and/or hydrophilic linkers derived from homocysteic acid, cysteic acid, glycine peptides, tetraethylene oxide, and the like, offset the hydrophobicity of the acridinium ring system to produce a more soluble label which can be attached to an antibody at higher loading before precipitation and aggregation problems are encountered. Additional compounds described herein contain linkers derived from short peptides and tetraethylene oxide which increase aqueous solubility due to hydrogen bonding with water molecules. The present invention also embraces reagents for multiple acridinium labeling for signal amplification composed of a peptide bearing several acridinium esters with sulfonate groups at regularly spaced intervals for increased solubility. The invention also embraces assays employing the above-described compounds.
