The spleen tissue is gently dissociated using enzymatic and mechanical methods, followed by immunomagnetic enrichment or other selective techniques to isolate macrophage populations while minimizing contamination by lymphocytes and other cell types. Each lot is checked for sterility, mycoplasma, and macrophage marker expression.
Yes. The cells retain stable expression of macrophage and activation markers and can be labeled with fluorochrome-conjugated antibodies for surface and intracellular staining. They generally tolerate flow cytometric analysis well. When cell sorting is required, we recommend using gentle sorting parameters and promptly re-plating the cells to allow them to recover, especially if you plan to perform downstream functional assays.
For long-term storage, vials should be kept in the vapor phase of liquid nitrogen. We do not recommend extended storage at -80°C beyond the transport period. Once thawed, cells should be used immediately; refreezing is not advised, as it may significantly impair viability and function. Following our thawing protocol and avoiding unnecessary temperature fluctuations will help preserve the full functional capacity of the cells.
