Macrophage Polarization Assay Service

The polarization state of macrophages is a critical determinant of their key functions in immune responses, serving as a central node linking innate and adaptive immunity while regulating inflammatory processes and tissue repair. Creative Biolabs' Macrophage Polarization Assay Service employs standardized stimulation protocols and a multi-parameter detection platform to enable systematic identification and functional analysis of M1, M2, and key subtype polarization phenotypes. A major strength of the service lies in its highly reproducible standardized workflows, extensive experience with both human primary cells and cell lines, and precise assessment of dynamic changes across the polarization continuum, effectively minimizing experimental variability arising from diverse cell sources and microenvironmental factors.

Introduction

Macrophage polarization is a fundamental manifestation of the remarkable functional plasticity exhibited by macrophages, representing their ability to differentiate into distinct functional phenotypes, namely the pro-inflammatory M1 and the anti-inflammatory M2 states, in response to specific microenvironmental cues. This process is precisely regulated by a complex array of stimuli, including cytokines (e.g., IFN-γ/GM-CSF for M1; IL-4/IL-10/IL-13/M-CSF for M2), pathogen-associated molecular patterns (PAMPs), and other signaling molecules. Conducting precise macrophage polarization assays is therefore critically important, as it enables the quantitative assessment of macrophage functional status, which is essential for elucidating disease mechanisms (such as chronic infection, cancer, and autoimmune disorders), evaluating immune responses, and developing targeted immunotherapeutic strategies.

Macrophage Polarization Assay Service at Creative Biolabs

Creative Biolabs' Macrophage Polarization Assay Service employs highly reproducible, standardized protocols to perform phenotypic identification and functional analysis of macrophages, whether derived from primary cells or cell lines. We deliver comprehensive and reliable polarization data, empowering you to gain deeper insights into macrophage functional states within specific disease models or under pharmacological intervention.

What we can offer

To ensure the phenotypic accuracy of our macrophage polarization models, we employ standardized induction protocols. These protocols use specific stimuli to treat primary cells (such as bone marrow-derived or peritoneal macrophages) and directionally induce the target subsets. And then we perform phenotypic validation based on the significantly expressed surface markers and characteristic cytokine profiles of each subset, providing robust data support for your research conclusions.
