GBP1 ELISA Kit (Human)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Guanylate Binding Protein 1, Interferon Inducible (GBP1) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Guanylate Binding Protein 1, Interferon Inducible (GBP1) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

GBP-1; GTP-binding protein 1; guanine nucleotide-binding protein 1; guanylate binding protein 1, interferon-inducible, 67kDa; guanylate-binding protein 1; huGBP-1; interferon-induced guanylate-binding protein 1.

Hydrolyzes GTP to GMP in 2 consecutive cleavage reactions. Exhibits antiviral activity against influenza virus. Promote oxidative killing and deliver antimicrobial peptides to autophagolysosomes, providing broad host protection against different pathogen classes.

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Guanylate Binding Protein 1, Interferon Inducible (GBP1) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Guanylate Binding Protein 1, Interferon Inducible (GBP1) . Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Guanylate Binding Protein 1, Interferon Inducible (GBP1), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm +/- 10nm. The concentration of Guanylate Binding Protein 1, Interferon Inducible (GBP1) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
