A drug is useless if it can't get inside the cell. This is the central challenge for lipid nanoparticles, cell-penetrating peptides, antibody-drug conjugates, and RNA therapeutics, the fastest-growing modalities in pharma. Every delivery team needs to know: how much got in, and into how many cells?

Cytely quantifies uptake at the single-cell level across conditions in seconds. Interactive gating lets you filter artifacts and isolate genuinely positive cells with visual verification. Replace "Nanoparticles" with your LNP-encapsulated mRNA or your cell-penetrating peptide and the workflow is identical.

How the assay runs

Segment cells → measure intracellular fluorescence intensity per cell → compare across conditions.

What you provide

  • Ch1: DAPI
  • Ch2: fluorescently labeled peptide, toxin, or compound (e.g., pHrodo, Alexa-labeled)

What you get

  • Mean intracellular fluorescence per cell
  • % cells with uptake

Ready to run

Cell-penetrating peptide uptake, cholera toxin binding and internalization, transferrin uptake, fluorescent glucose uptake (2-NBDG), fatty-acid / lipid uptake, labeled LDL uptake (e.g., DiI-LDL), exosome / extracellular vesicle (EV) uptake, nanoparticle uptake, receptor-mediated endocytosis, any fluorescently labeled compound uptake assay.

Inquire for support

Concentration-dependent uptake profiles, endosomal escape quantification, uptake kinetics (timelapse).
