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.
