简介:
Overview
This article describes a methodology to quantitate the expression of 96 genes and 18 surface proteins by single cells ex vivo. This approach allows for the identification of differentially expressed genes and proteins in virus-infected cells relative to uninfected cells, specifically applied to SIV-infected CD4 + T cells isolated from rhesus macaques.
