技術規格
工作原理 | 本試劑盒采用的是雙抗體夾心法酶聯免疫吸附檢測技術(ELISA)。測定樣品中人腫瘤壞死因子β水平。向預先包被了抗人腫瘤壞死因子β抗體的酶標孔中,加入標準品和樣本,溫育後,加入生物素標記的抗腫瘤壞死因子β抗體。再與HRP標記的鏈黴親和素結合,形成免疫複合物,再經過溫育和洗滌,去除未結合的酶,然後加入顯色底物TMB,產生藍色,並在酸的作用下轉化成最終的黃色。最後,在450 nm處測定反應孔樣品吸光度(OD)值,樣本中的人腫瘤壞死因子β濃度與OD值成正比,通過繪製標準曲線計算出樣本中人腫瘤壞死因子β的濃度。 |
Purpose | This assay employs the Sandwich enzyme immunoassay technique. Determine the level of Human TNF-β(Tumor Necrosis Factor Beta) in the sample. Add standard and sample to the microplate that have been pre-coated with Anti-Human TNF-β(Tumor Necrosis Factor Beta) antibody. After incubation, add Biotin-conjugated anti-Human TNF-β(Tumor Necrosis Factor Beta) antibody. It is then combined with HRP-conjugated streptavidin to form an immune complex, then incubated and washed to remove unbound enzyme, and then added to the chromogenic substrate TMB to produce a blue color, and converted to the final yellow under the action of acid. Finally, the absorbance (OD) value was measured at 450 nm. The concentration of Human TNF-β(Tumor Necrosis Factor Beta) in the sample was proportional to the OD value. The concentration of Human TNF-β(Tumor Necrosis Factor Beta) in the sample can be calculated by drawing a standard curve. |
靈敏度 | 9.38 pg/mL |
Sensitivity | 9.38 pg/mL |
檢測範圍 | 15.63-1000 pg/mL |
Examination range | 15.63-1000 pg/mL |
特異性 | 可檢測樣本中的人腫瘤壞死因子β,且與其類似物無明顯交叉反應。 |
Specificity | This kit recognizes Human TNF-β(Tumor Necrosis Factor Beta) in samples. No significant cross-reactivity or interference between Human TNF-β(Tumor Necrosis Factor Beta) and analogues was observed. |
重複性 | 三種不同濃度的樣本在同一塊板子上分別檢測20次,以及在不同的板子上分別檢測20次,板內和板間變異係數均小於10%。 |
Repeatability | Three different concentrations of samples were detected 20 times on the same board and 20 times on different boards. Within the plate or between the plates, the coefficient of variation is <10%. |
回收率 | 分別往稀釋不同倍數的5個樣本中加入已知濃度的目標蛋白,做回收實驗,得出回收率範圍和平均回收率。 |
Recovery | A known concentration of the target protein was added to 5 samples which were diluted to different multiples, and a recovery experiment was performed to obtain a recovery range and an average recovery rate. |
