Human Fc Fragment Of IgA Receptor ELISA Kit

Listed in the Antibodies.com catalogue as a sandwich ELISA for human samples, this kit targets the Fc Fragment Of IgA Receptor, also referred to as CD89. The manufacturer's description states that it is intended for the in vitro quantitative determination of human CD89 in serum, plasma, tissue homogenates or other biological fluids, using a pre-coated microplate and colorimetric detection read at 450 nm.

Reported performance includes an assay range of 0.781–50 ng/ml, a sensitivity of 0.35 ng/ml and a total assay time of 4 h 30 m. Sample-recovery validation showed averages of 91% in serum (range 80–102%, n=5), 90% in EDTA plasma (range 81–100%, n=5) and 84% in heparin plasma (range 80–89%, n=5). Dilution-linearity testing across 1:2, 1:4, 1:8 and 1:16 ratios returned 70–107%, 89–93%, 86–104% and 80–103% for serum; 95–100%, 85–110%, 81–99% and 90–102% for EDTA plasma; and 77–104%, 88–95%, 94–104% and 80–107% for heparin plasma (each n=5).
