Guidelines for single-cell proteomic experiments

Henry Ford remarked that coming together is a beginning, staying together is progress, and working together is success. Working together is also more fun. Thus, from the very beginning, we sought to help colleagues adopt and use single-cell proteomic methodologies that our laboratory developed, and to do so following best practices To develop and disseminate … Continue reading Guidelines for single-cell proteomic experiments

Adsorption losses during single-cell proteomics

Proteins are wonderfully diverse! Their physicochemical diversity is essential to animating life, to performing the myriad functions necessary to process energy, nutrients and information in living systems. The physicochemical diversity of proteins also poses challenges to proteomic analysis. Different amino acid sequences can adsorb to various surfaces, thus resulting in losses, reduced sensitivity and even … Continue reading Adsorption losses during single-cell proteomics

Framework for increasing proteomics throughput

Simultaneously achieving achieving deep proteome coverage, high data completeness, high throughput, and high sensitivity has been a long standing challenge in the field of proteomics. This challenge is particularly evident and relevant to single-cell proteomics, which has the potential to enable mechanistic investigations of key biological questions, such as signaling mechanisms based on protein binding, modifications, and … Continue reading Framework for increasing proteomics throughput

Direct causal mechanisms

Understanding biological systems: In search of direct causal mechanisms The advent of DNA-microarrays spurred a vigorous effort to reverse engineer biological networks. Recently, these efforts have been reinvigorated by the availability of RNA-seq data from perturbed and unperturbed single cells. In the talk below, I discuss the opportunities and limitations of using such data for … Continue reading Direct causal mechanisms

Single-cell analysis

The success of imaging technologies The molecular and functional differences among the cells making our bodies have been appreciated for many decades. Yet, the tools to study them were very limited. In the last couple of decades, we have began developing increasingly powerful technologies for molecular single-cell measurements. Currently, the most widely used high-throughput methods … Continue reading Single-cell analysis
