Human RNF39 (Ring Finger Protein 39) Microsample ELISA Kit

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 Human RNF39. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human RNF39. 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 Human RNF39, 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 Human RNF39 in the samples is then determined by comparing the OD of the samples to the standard curve.Detection Range: 0.32-20 ng/mL. Sensitivity: 0.128 ng/mL. Assay Type: Sandwich. Standard: 20 ng/mL. Sample Type: sTissue homogenates and other biological fluids.. Assay duration: 3.5h. Protein Function: Plays an inhibitory role in anti-RNA viral innate immunity by targeting the adapter DDX3X and promoting its 'Lys-48'-linked polyubiquitination (PubMed:33674311). Alternatively, enhances the cGAS-STING pathway activation by promoting 'Lys-63'-linked ubiquitination of STING1, facilitating the STING1-TBK1 complex formation and STING1 activation (PubMed:39255680) , (Microbial infection) Plays a positive role in human immunodeficiency virus (HIV-1) replication [The Uniprot Consortium]
