Sandwich ELISA - Caffeine ELISA Kit - Extracellular (AB325037)
Interpolated concentration of native Caffeine was measured in duplicate at different sample concentrations. Undiluted samples are 1 : 2,000 Human serum, and 1 : 4,000 Human plasma (citrate), plasma (EDTA) and plasma (heparin). The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). Sample dilutions are made in Cell Extraction Buffer SSW.

제품 세부 정보
Caffeine ELISA Kit- Extracellular (ab325037) is a rapid single-wash competitive 90-min ELISA to measure Caffeine in Serum, Citrate Plasma, EDTA Plasma, Heparin Plasma, Saliva, Urine, Cell Culture Supernatant. This SimpleStep sensitivity is 2.391 pg/ml.<br><br><strong>How the assay works</strong><br><br>Caffeine ELISA Kit- Extracellular (ab325037) uses an affinity tag recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to competitive ELISA® allows the formulation of the antibody-analyte complex in a single step, saving you significant time at the bench.<br>In the antigen-down format, the labeled antigen and the unlabeled antigen from your sample compete to bind to the HRP-tagged capture antibody. In the antibody-down format, the HRP-tagged antigen and the unlabeled antigen from your sample compete to bind to the capture antibody. The component labeled with the CaptSure™ affinity tag, either antigen or antibody, binds to the SimpleStep ELISA® plate. A decrease in signal indicates the presence of antigen in the sample when compared to wells containing only the labeled antigen.<br><br><strong>Assay Specificity</strong><br><br>Our SimpleStep ELISA® kits use recombinant monoclonal antibodies rigorously validated to ensure the highest level of consistency and reproducibility, improved sensitivity and specificity and ease of scalability and security of supply.<br>Please refer to our protocol booklet for more details.<br><br><strong>Caffeine (ab325037) protocol summary</strong><br><br>1. Mix : add samples / standards to the wells together with the Captsure conjugate solution and HRP Conjugate solution. Incubate 1 hr at room temperature<br>2. Wash<br>3. Add TMB development solution - incubate for 10 min<br>4. Add Stop solution<br>5. Read the results on a plate reader at 450 nm<br><br>
