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. Prepare all reagents, samples and standards;\n2. Add 100µL standard or sample to each well. Incubate 1 hours at 37°C;\n3. Aspirate and add 100µL prepared Detection Reagent A. 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 Defensin Beta 2 (DEFb2). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Defensin Beta 2 (DEFb2). 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 Defensin Beta 2 (DEFb2), 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 Defensin Beta 2 (DEFb2) 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;\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReferences Citing This Product\u003c\/b\u003e: \u003ca href=\"http:\/\/www.ncbi.nlm.nih.gov\/pubmed\/24124699\"\u003eIdentification of sociodemographic and clinical factors associated with the levels of human β-defensin-1 and human β-defensin-2 in the human milk of Han Chinese\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"http:\/\/researchcommons.waikato.ac.nz\/handle\/10289\/8785\"\u003eThe Assessment of Vitamin D, Antimicrobial Peptides and Procalcitonin in Bronchiectasis\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"http:\/\/www.ncbi.nlm.nih.gov\/pubmed\/25444792\"\u003eOn birth single dose live attenuated OPV and BCG vaccination induces gut cathelicidin LL37 responses at 6 week of age: A natural experiment\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"http:\/\/search.ebscohost.com\/login.aspx?direct=true\u0026amp;profile=ehost\u0026amp;scope=site\u0026amp;authtype=crawler\u0026amp;jrnl=16629795\u0026amp;AN=120009165\u0026amp;h=jupfn%2FMiDiaZL8LtOt7Jno1xWtb%2FBt0ZZXQp8Soeo46uaDs%2BcqHXIAVZpBeIlAPgFqTE%2F%2Fwn0zNlBBi1agdxpw%3D%3D\u0026amp;crl=c\"\u003eThe Level of Inflammatory Cytokines and Antimicrobial Peptides after Composite Material Implantation and Contamination with Bacterial Culture.\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"https:\/\/content.sciendo.com\/view\/journals\/prolas\/73\/2\/article-p177.xml\"\u003eInfluence of Antibiotic-Impregnated Biomaterials on Inflammatory Cytokines\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"https:\/\/www.hindawi.com\/journals\/jir\/2019\/9708769\/abs\/\"\u003eDamage-Associated Molecular Patterns and Myeloid-Derived Suppressor Cells in Bronchoalveolar Lavage Fluid in Chronic Obstructive Pulmonary Disease Patients\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/34362937\/\"\u003eHuman beta defensin levels and vaginal microbiome composition in post-menopausal women diagnosed with lichen sclerosus\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/35687771\/\"\u003eRegulatory T cells, damage-associated molecular patterns, and myeloid-derived suppressor cells in bronchoalveolar lavage fluid interlinked with chronic obstructive …\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":48696693194852,"sku":"SEA072Hu","price":1093.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/files\/no_image_default_image-jpeg_54492274-8c31-4266-82fa-ab37a4154473.jpg?v=1783134333","url":"https:\/\/www.genebiosystems.com\/en-us\/products\/defb2-elisa-kit-for-human","provider":"GeneBio ","version":"1.0","type":"link"}
