Intra-assay Precision (Precision within an assay): CV%<8% | ||||||
Three samples of known concentration were tested twenty times on one plate to assess. | ||||||
Inter-assay Precision (Precision between assays): CV%<10% | ||||||
Three samples of known concentration were tested in twenty assays to assess. | ||||||
To assess the linearity of the assay, samples were spiked with high concentrations of pig TNF in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay. | ||||||

This ELISA kit provides quantitative measurement of TNF-α in porcine samples, supporting immunology research where this master pro-inflammatory cytokine drives innate immune activation, sepsis modeling, and tissue inflammation. Because porcine TNF-α levels can shift rapidly from undetectable baseline concentrations to high nanogram ranges during acute immune challenge, the kit is designed to capture this dynamic expression across diverse experimental contexts.
Detection Range: The 23.5–1500 pg/mL range spans the concentrations typically observed in LPS-stimulated porcine whole blood, activated alveolar macrophage supernatants, and serum from experimentally induced endotoxemia, reducing the need for extensive serial dilution in most acute inflammation models.
Sensitivity: At 11.75 pg/mL, the kit detects the low constitutive TNF-α levels present in unstimulated porcine monocyte cultures and baseline serum, enabling accurate measurement of early innate immune priming before overt inflammatory amplification.
Sample Compatibility: Validation across serum, plasma, cell culture supernatants, and tissue homogenates allows researchers to correlate systemic circulating TNF-α with local production in gut, lung, or lymphoid tissue — critical for porcine mucosal immunology and organ-level inflammation studies.
Assay Efficiency: The 1–5 hour protocol using only 50–100 µL accommodates limited-volume neonatal piglet samples and high-throughput screening of multiple treatment groups common in swine vaccine trials.
This kit directly supports research in porcine sepsis modeling, PRRSV-associated immunopathology, and intestinal barrier dysfunction studies.
Sample type: Serum
Sample species: Pig
Sample dilution: : 1:10
Review: We used the CSB-16980p-IS kit to detect the LPS-induced piglet model, and through the use of this kit, we found that LPS caused an increase in the expression of tumor necrosis factor in piglet serum.
