Our Monocytes are isolated by a negative selection process that prevents the activation of cells. Monocytes from Astarte Biologics function as expected:
- phagocytize yeast
- produce cytokines
- migrate in response to chemotactic agents
Under the right culture conditions, monocytes can differentiate into dendritic cells, Langerhans cells or macrophages.

|Monocytes were thawed and cultured in 24 well plates at 1 million cells per well Culture medium was collected after 48 hours Cytokines were quantitated by Pierce Biotechnology using their Searchlight Proteome Array™|
Monocytes were incubated with Alexa Fluor® 595 conjugated zymosan for one hour, fixed and counterstained with Alexa Fluor® 488 conjugated phalloidin. See the phagocytosis protocol here for details of the method.
