Human Beta-defensin 119 (DEFB119) ELISA Kit

Designed by Assay Genie for quantitative detection of human Beta-defensin 119 (DEFB119), this sandwich ELISA kit targets a secreted antimicrobial peptide that contributes to innate immune defense. The assay is specific to natural and recombinant human Beta-defensin 119 and is intended for research into immune function, inflammation, and infectious disease.

The kit is suitable for use with human samples including serum, plasma, tissue homogenates, cell culture supernates, and other biological fluids. According to the manufacturer's specifications, the detection range is 0.312–20 ng/mL with a sensitivity of 0.12 ng/mL. Reported precision is an intra-assay CV of 6.1% and an inter-assay CV of 9.3%.

Linearity has been validated across serum, EDTA plasma, and heparin plasma at dilutions of 1:2, 1:4, 1:8, and 1:16, with average recovery of 83% for serum (range 80–89%) and 85% for plasma (range 80–91%). For research use only.
