Figure 5From: Increasing the sensitivity of reverse phase protein arrays by antibody-mediated signal amplification Comparing the sensitivity of standard NIR detection and AMSA for endogenous proteins. Detection of beta-Catenin, PDK1, and PCNA in the human colon cancer cell line HT-29 and in the human breast cancer cell lines T47D and MCF7 comparing AMSA with standard NIR. The limit of detection is indicated as red or blue line.Back to article page
