| 英文名稱： | ELISA Kit for Tetrahydrofolic Acid (THFA) |
| 基因別稱： | H4FA; THF; Tetrahydrofolate |
| 實驗步驟： | 1. Prepare all reagents, samples and standards; 2. Add 50µL standard or sample to each well. And then add 50µL prepared Detection Reagent A immediately. Shake and mix. Incubate 1 hour at 37°C; 3. Aspirate and wash 3 times; 4. Add 100µL prepared Detection Reagent B. Incubate 30 minutes at 37°C; 5. Aspirate and wash 5 times; 6. Add 90µL Substrate Solution. Incubate 10-20 minutes at 37°C; 7. Add 50µL Stop Solution. Read at 450 nm immediately. |
| 檢測范圍： | 1.23-100ng/mL |
| 最低檢測限： | The minimum detectable dose of this kit is typically less than 0.44ng/mL |
| 適應(yīng)生物： | Pan-species (General) |
| 樣本： | Serum, plasma, tissue homogenates, cell lysates, cell culture supernates and other biological fluids |
| 實驗時長： | 2h |
| 種類： | Competitive Inhibition |
| 特異性： |
This assay has high sensitivity and excellent specificity for detection of Tetrahydrofolic Acid (THFA). |
| 精度： |
Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Tetrahydrofolic Acid (THFA) 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. |
| 實驗原理： | This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to Tetrahydrofolic Acid (THFA) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled Tetrahydrofolic Acid (THFA) and unlabeled Tetrahydrofolic Acid (THFA) (Standards or samples) with the pre-coated antibody specific to Tetrahydrofolic Acid (THFA). After incubation the unbound conjugate is washed off. Next, avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of Tetrahydrofolic Acid (THFA) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Tetrahydrofolic Acid (THFA) in the sample. |
