THP1-XBlue™-CD14 Cells

THP1-XBlue™-CD14 cells derive from the THP1-XBlue™ cell line. THP1-XBlue™-CD14 cells stably express the human CD14 gene, encoding a macrophage-specific differentiation antigen. CD14 interacts with several TLRs in the induction of the signaling cascade upon TLR stimulation and its overexpression was found to increase the reponse to the majority of TLR ligands.

THP1-XBlue™-CD14 cells express an NF-κB/AP-1-inducible SEAP (secreted embryonic alkaline phosphatase) reporter gene. TLR stimulation in THP1-XBlue™-CD14 cells induces signaling cascades leading to the activation of NF-κB and AP-1 and the subsequent production of SEAP. The reporter protein is easily detectable and measurable when using QUANTI-Blue™, a medium that turns purple/blue in the presence of SEAP.
