Isolation of murine hepatic myeloid cells with high yield and purity using immunomagnetic beads for subset analysis

There are numerous established techniques for isolating hepatic myeloid cells; however, preserving their phenotypic and functional characteristics can be challenging. We present a straightforward and efficient method to isolate hepatic myeloid cells, including Kupffer cells and lymphocyte antigen 6 complex, locus C⁺ (Ly6C⁺) monocytes/macrophages. The procedure involves perfusion of the liver with collagenase and purification with immunomagnetic particles. This protocol ensures the isolation of large quantities of purified, viable, and functional cells without influencing their physiological characteristics. For complete details on the use and execution of this protocol, please refer to Wu et al. (2019).¹.
