The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition.\nTo minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eAssay procedure summary\u003c\/b\u003e: 1.

Incubate 1 hour at 37°C;\n4. Aspirate and wash 3 times;\n5. Add 100µL prepared Detection Reagent B. Incubate 30 minutes at 37°C;\n6. Aspirate and wash 5 times;\n7. Add 90µL Substrate Solution. Incubate 10-20 minutes at 37°C;\n8. Add 50µL Stop Solution. Read at 450nm immediately.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eTest principle\u003c\/b\u003e: 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 Immunoglobulin G4 (IgG4). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Immunoglobulin G4 (IgG4). 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 Immunoglobulin G4 (IgG4), 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 Immunoglobulin G4 (IgG4) in the samples is then determined by comparing the O.D. of the samples to the standard curve.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eResearch Area\u003c\/b\u003e: Infection immunity;Immune molecule;\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReferences Citing This Product\u003c\/b\u003e: \u003ca href=\"http:\/\/www.hindawi.com\/journals\/bmri\/aa\/345413\/\"\u003eThe Effect of CXC Motif Chemokine 13 on Hepatocellular Carcinoma Associates with Wnt Signaling\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"http:\/\/www.ncbi.nlm.nih.gov\/pubmed\/25194335\"\u003eUtility of serum IgG, IgG4 and carbonic anhydrase II antibodies in distinguishing autoimmune pancreatitis from pancreatic cancer and chronic pancreatitis\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"http:\/\/www.ncbi.nlm.nih.gov\/pubmed\/25529861\"\u003eBeneficial effect of T follicular helper cells on antibody class switching of B cells in prostate cancer\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"http:\/\/www.ncbi.nlm.nih.gov\/pubmed\/25561924\"\u003eEffect of Cysteamine on Cell Growth and IgG4 Production in Recombinant Sp2.0 Cells\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"http:\/\/www.ncbi.nlm.nih.gov\/pubmed\/26377996\"\u003eLoss of interleukin-21 leads to atrophic germinal centers in multicentric Castleman’s disease\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"http:\/\/www.ncbi.nlm.nih.gov\/pubmed\/26161394\"\u003eThe Effect of C-X-C Motif Chemokine 13 on Hepatocellular Carcinoma Associates with Wnt Signaling\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"http:\/\/thailand.digitaljournals.org\/index.php\/ARJ\/article\/view\/30785\"\u003eIncreasing Foxp3, IgG4 and improvement quality of life after immunotherapy treatment in allergic rhinitis patients\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":48696751652964,"sku":"SEA234Hu","price":897.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/files\/no_image_default_image-jpeg_b79f1d45-6af0-47e4-bc95-a7845c0d7a81.jpg?v=1783136250","url":"https:\/\/www.genebiosystems.com\/en-fr\/products\/igg4-elisa-kit-for-human","provider":"GeneBio ","version":"1.0","type":"link"}
