I need to profile heterogeneity in complex samplesMilo 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. |
|
I need protein validation of my single-cell RNA-seq dataUse conventional western antibodies to validate your single-cell RNA-seq data with single-cell protein data. Plus, scWest chips can be archived for up to 9 months after you run them so you have plenty of time to get your sequencing results back before you have to probe for your targets of interest. |
|
I need multiplexing to detect multiple proteins at the single-cell levelSimultaneously detect 12+ proteins in your sample, all at the single-cell level, using spectral and size-based multiplexing strategies. You can even strip & reprobe scWest chips up to 9 times for higher multiplexed studies! |
|
I need to simplify my phospho-flow signaling studiesEliminate the fixation and permeabilization steps of flow/FACS! Milo chemically lyses the cells captured on the scWest chip before analysis to gain access to intracellular and intranuclear compartments more easily than with flow cytometry. By lysing the cells, Milo can detect challenging proteins like transcription factors and even methylated histones! You can also use Milo's sizing step to separate out non-specific binding, which is more common with phospho-specific antibodies and cannot be resolved with flow. |
|
I need to detect proteins that lack good flow antibodiesMilo is an open platform so you can use the large commercial catalog of Western antibodies which is 10-100x larger than the flow/FACS catalog. Don't get stuck without a flow antibody against your target of interest again. |
|
I want to measure protein isoform heterogeneityMilo's molecular weight sizing step can resolve protein isoforms that differ in molecular weight, allowing you to measure how many cells in your sample express one isoform, the other isoform, or both isoforms. Try that with flow! |
|
I need to measure gene editing efficiency or effect in low efficiency gene editing systemsMilo can quantify the percentage of cells in your sample that express an inserted gene, even in low efficiency systems. Plus, you can simultaneously measure your edited gene and downstream effect markers to understand the impact of the gene on the cells that have been edited. |
|
I need to measure protein expression in low abundance samplesMilo can analyze samples which contain as low as 10,000 single-cells so you no longer have to have collect millions of cells to analyze protein expression. The number of cells captured scales with the number of cells loaded so even lower abundance samples are possible. Milo can also characterize highly enriched FACS-sorted cell populations which don't contain enough cells to analyze with other techniques. |

"I was looking at two different isoforms of a protein, and it was important to know if the cells were expressing just one versus the other or both in a given cell. That was tricky until Milo came. We’re also getting more relevant information because Milo allows us to look at expression of this protein in tissue biopsies."

"We have been pairing Milo with single-cell real time qPCR data. We have the RNA and we know the transcripts are present. We used Milo to confirm our results and quantify the amount of protein that is in each individual cell."

"With Milo, we observed a level of single-cell protein expression heterogeneity in our purified intestinal stem cell population that was not previously possible with conventional Western blotting."
