Single-Cell High-Resolution Detection and Quantification of Protein Isoforms Differing by a Single Charge Unit.

Single-Cell High-Resolution Detection and Quantification of Protein Isoforms Differing by a Single Charge Unit. Methods Mol Biol. 2019;1855:501-509 Authors: Koelsch KA Abstract Isoelectric focusing (IEF) is an electrophoretic technique that enables the separation of proteins based on their isoelectric points. Until recently, this valuable method was not feasible for single-cell applications, which are necessary to interrogate heterogeneous cell populations. Herein we highlight a recently published method enabling the analysis of single-cell proteomics, which utilizes microfluidics coupled with IEF, photocapture, and immunoprobing of the protein in the same micro-gel, which can be stripped and reprobed multiple times.
