Flow Cytometer as a QC Tool for Assessing Bead Coating Efficacy

Attaching ligands to bead surfaces is a valuable technique for the development of a variety of assays and flow applications. While there are several means of ligand attachment, covalent coupling is often employed for the immobilization of...

Fluorescent Microspheres: Internal vs. External Labeling

Continuing our discussion of the different types of microspheres that can be advantageous for flow cytometry, we think it is useful to now discuss the different ways beads may be labeled with fluorophore and the typical characteristics that...

Why We Don't Offer Dyed Silica

In the previous blog, Refractive Index and Small Particle Analysis, we discussed some of the reasons why people want to employ silica nanoparticles as calibrators when analyzing extracellular vesicles on the flow cytometer. So, why don’t we...

Refractive Index and Small Particle Analysis

We often receive requests for silica rather than polystyrene size standards for flow cytometric studies, notably for the analysis of extracellular vesicles. This is because the refractive index (RI) of silica (~1.44) is closer to that of cells (~1....

Extracellular Vesicle Analysis By Flow Cytometry

When studying extracellular vesicles, it is helpful to have some tools to guide the operator in their analysis. Particle reference standards assist the investigator by providing confidence in sizing, quantitation and particle count. In...
