Milo™ is the world’s first Single-Cell Western platform. He measures protein expression in thousands of single cells in a single run so you can profile heterogeneity in your samples. Just load your cell suspension and the scWest chip captures ~1,000 single-cells. Milo then does a fast, 1 minute SDS-PAGE separation on each single-cell lysate on-chip. Then just probe with your favorite conventional Western antibodies to measure up to 4 proteins per cell simultaneously. Use Single-Cell Westerns to unlock the single-cell proteome and measure more of the proteome than is possible with any other single-cell technique.

  • Introduction

    Milo measures protein expression in ~1,000 single-cells in one 4 hour experiment so you can quantify expression heterogeneity of your target and the percentage of cells in your sample that are target positive.
