THP-1 h

The THP-1h cell line is a highly characterized and functionally enhanced human monocytic model, specifically selected for its superior responsiveness and phenotypic stability compared to standard monocytic lineages. Derived from a patient with acute monocytic leukemia, this "High-Response" (h) variant serves as a critical in vitro tool for researchers who require consistent, robust performance in inflammatory signaling, macrophage polarization, and vaccine development assays.

• Enhanced Differentiation Kinetics: THP-1h cells exhibit an accelerated and highly synchronized transition from monocytes to macrophage-like cells upon induction (e.g., with PMA). This leads to a more uniform cell population, providing higher sensitivity for studying M1/M2 macrophage polarization and tissue-specific immunity.
• Superior Inflammasome Sensitivity: Our THP-1h variant is validated for its robust activation of the NLRP3 inflammasome pathway. It demonstrates significantly higher secretion levels of pro-inflammatory cytokines like IL-1β and TNF-α following TLR-4 priming, making it the ideal substrate for screening small-molecule anti-inflammatory inhibitors.
• Optimal Phagocytic and Chemotactic Activity: These cells maintain high expression of essential surface markers such as CD14, CD11b, and CCR2. This ensures superior performance in functional assays, including pathogen phagocytosis, efferocytosis, and chemotactic migration studies.
• High Post-Thaw Recovery & Purity: Each lot is rigorously screened for exceptional post-thaw viability (>90%) and genetic stability. Their predictable doubling time and consistent morphology minimize experimental drift, ensuring that your high-throughput screening (HTS) data remains reproducible across multiple passages.

By utilizing the THP-1h cell line, you gain a high-fidelity, human-derived system that offers the sensitivity and reliability required for the most demanding preclinical research and drug discovery applications.
