| 英文名稱： | ELISA Kit for Semaphorin 4B (SEMA4B) |
| 基因別稱： | SEMAC; SEMC; Sema Domain, Transmembrane Domain And Cytoplasmic Domain Protein 4B |
| 實(shí)驗(yàn)步驟： | 1. Prepare all reagents, samples and standards; 2. Add 100µL standard or sample to each well. Incubate 2 hours at 37°C; 3. Aspirate and add 100µL prepared Detection Reagent A. Incubate 1 hour at 37°C; 4. Aspirate and wash 3 times; 5. Add 100µL prepared Detection Reagent B. Incubate 30 minutes at 37°C; 6. Aspirate and wash 5 times; 7. Add 90µL Substrate Solution. Incubate 10-20 minutes at 37°C; 8. Add 50µL Stop Solution. Read at 450nm immediately. |
| 檢測(cè)范圍： | 0.156-10ng/mL |
| 最低檢測(cè)限： | The minimum detectable dose of this kit is typically less than 0.055ng/mL |
| 適應(yīng)生物： | Homo sapiens (Human) |
| 樣本： | Serum, plasma, tissue homogenates, cell lysates and other biological fluids |
| 實(shí)驗(yàn)時(shí)長(zhǎng)： | 3h |
| 種類： | Double-antibody Sandwich |
| 特異性： |
This assay has high sensitivity and excellent specificity for detection of Semaphorin 4B (SEMA4B). |
| 精度： |
Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Semaphorin 4B (SEMA4B) were tested 20 times on one plate, respectively. |
| 穩(wěn)定性： |
The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. |
| 實(shí)驗(yàn)原理： | 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 Semaphorin 4B (SEMA4B). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Semaphorin 4B (SEMA4B). 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 Semaphorin 4B (SEMA4B), 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 Semaphorin 4B (SEMA4B) in the samples is then determined by comparing the O.D. of the samples to the standard curve. |
