Mouse Macrophage Reporter Cell Line

RAW-Blue™ cells are derived from the murine RAW 264.7 macrophages with chromosomal integration of a secreted embryonic alkaline phosphatase (SEAP) reporter construct inducible by NF-κB and AP-1. RAW-Blue™ cells express many pattern-recognition receptors (PRRs), including toll-like receptors (TLRs), NOD-like receptors (NLRs), RIG-I-like receptors (RLRs) and C-type lectin receptors (CLRs).

Therefore, RAW-Blue™ cells can be used as:

  • TLR reporter cells: they express all TLRs, with the exception of TLR5, at different levels
  • NOD reporter cells: they express NOD2 and, to a lesser extent, NOD1
  • RLR reporter cells: they express RIG-I and MDA-5
  • CLR reporter cells: they express Dectin-1

The presence of agonists of these PRRs induces signaling pathways leading to the activation of NF-κB and AP-1, and the subsequent production of SEAP.

Levels of SEAP can be easily monitored using the detection medium QUANTI-Blue™.



TLR and NOD stimulation profile in RAW-Blue™ Cells
TLR and NOD stimulation profile in RAW-Blue™ Cells

RAW-Blue™ Cells were incubated with TLR or NOD agonists: TLR2 (HKLM, 1.108 cells/ml), TLR1/2 (Pam3CSK4, 100 ng/ml), TLR2/6 (FSL-1, 100 ng/ml), TLR3 (poly(I:C), 10 μg/ml), TLR4 (LPS-EK, 1 μg/ml), TLR5 (RecFLA-ST, 1 μg/ml), TLR7 (CL075, 300 ng/ml), TLR9 (ODN1826, 10 μg/ml), NOD1 (Tri-DAP, 10 μg/ml), NOD2 (MDP, 10 μg/ml). After 24h incubation, TLR and NOD stimulation was assessed by measuring the levels of SEAP using QUANTI-Blue™.

Response of RAW-Blue™ cells to Dectin-1 and TLR2 agonists
Response of RAW-Blue™ cells to Dectin-1 and TLR2 agonists

RAW-Blue™ cells were stimulated with FSL-1 (10 ng/ml), zymosan (10 μg/ml), depleted zymosan (100 μg/ml), HKSC (10e8 cells/ml) or HKCA (10e8 cells/ml) in the presence or absence of 10 μg/ml of an anti-mTLR2 (clone T2.5) or anti-mDectin-1 monoclonal antibody.
After 24h incubation, NF-kB activation was assessed by measuring the levels of SEAP in the supernatant by using QUANTI-Blue™.
