An improved method for the retrieval of cultured macrophages
Journal of Immunological Methods
|November 12, 1982
Abstract:
We report a simple procedure for the maintenance and retrieval of rodent peritoneal macrophages on dialysis membrane supports. Culture units are easily constructed from plastic petri dishes and dialysis membranes. Macrophages adhere readily but are detached easily from the dialysis membrane by mild mechanical agitation. Cell viability remains high and the morphologic and functional characteristics of the macrophages are maintained.
Insights
