This kit quantitatively measures mouse IL-1β, a master pro-inflammatory cytokine central to innate immune activation, inflammasome signaling, and fever response. Because IL-1β is often released in sharp, transient bursts following stimuli like LPS challenge or NLRP3 inflammasome activation, accurate capture across both baseline and induced conditions demands a carefully calibrated assay.
Detection Range: The 12.5–800 pg/mL range spans resting-state serum levels in naïve mice through the elevated concentrations typical of acute inflammatory models such as endotoxemia or colitis, minimizing the need for serial dilutions while covering most in vivo and in vitro experimental conditions.
Sensitivity: At 6.25 pg/mL, the kit detects the low basal IL-1β secretion from unstimulated bone marrow-derived macrophages or dendritic cells, enabling meaningful fold-change calculations between vehicle and treatment groups.
Sample Compatibility: Validation across serum, plasma, cell culture supernatants, and tissue homogenates allows researchers to correlate systemic circulating IL-1β with local production at the tissue or cellular level within a single experimental cohort, supporting integrated inflammasome-activation studies.
Assay Efficiency: The assay requires only a 50µL sample loading volume, which can be diluted by 2 times, effectively demanding just 25µL of precious sample material. This "mini sample" feature makes it ideal for studies with limited sample availability. The 50 µL sample volume and 3.5-hour protocol accommodate limited volumes from murine cardiac bleeds and small-scale primary macrophage cultures, enabling same-day data acquisition.
This kit directly supports studies in sepsis modeling, sterile inflammation, and NLRP3-driven autoinflammatory disease.
