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.
We're making more! The next batch is expected to be released December 9.
This product is currently out of stock.

|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.
