Detection and quantification of the Bcr/Abl chimeric protein on biochips using LDI-TOF MS

Chem Commun (Camb). 2014 May 14;50(37):4831-4. doi: 10.1039/c4cc01332h.

Abstract

The Bcr/Abl chimeric protein was captured by two antibodies, anti-Bcr on gold nanoparticles (AuNPs) and anti-Abl on a biochip, in a sandwich assay format. The presence of the Bcr/Abl in cells was then verified by amplified LDI-TOF MS signals, and relative amounts were quantified using AuNPs coated with deuterated alkanethiols as an internal standard.
