Human Melatonin,MT ELISA Kit
Product Details
| Description |
The Human Melatonin (MT) ELISA Kit enables the quantification of human (MT) in solution, including serum, plasma, and tissue homogenates. The kit uses the double antibody Sandwich-ELISA technique. Samples, standards, biotin-labeled MT detection antibody, and HRP-avidin are successively added to the microwell plate wells pre-coated with anti-human MT antibody. After incubation and thorough washing, the substrate TMB is pipetted into the wells. The HRP catalyzes TMB, rendering the solution turns blue. The solution finally changes from blue to yellow under the action of the stop solution. The intensity of the color is positively correlated with human melatonin in the sample. Read the absorbance (OD value) with a microplate reader at the wavelength of 450nm, and the MT concentration in the sample can be calculated. This kit has been verified to have high sensitivity, strong specificity, good linearity, recovery of 90%-110%, precision less than 10%, and consistency between batches. Refer to... Read more |

| Linearity |
| To assess the linearity of the assay, samples were spiked with high concentrations of human MT in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay. |

| Materials provided |
- A micro ELISA plate --- The 96-well plate has been pre-coated with an anti-human MT antibody. This dismountable microplate can be divided into 12 x 8 strip plates.
- Two vials lyophilized standard --- Dilute a bottle of the standard at dilution series, read the OD values, and then draw a standard curve.
- One vial Biotin-labeled MT antibody (100 x concentrate) (120 μl/bottle) ---Act as the detection antibody.
- One vial HRP-avidin (100 x concentrate) (120 μl/bottle) --- Bind to the detection antibody and react with the TMB substrate to make the solution chromogenic.
- One vial Biotin-antibody Diluent (15 ml/bottle) ---Dilute the Biotin-antibody.
- One vial HRP-avidin Diluent (15 ml/bottle) ---Dilute the HRP-avidin solution.
- One vial Sample Diluent (50 ml/bottle)---Dilute the sample to an appropriate concentration.
- One vial Wash Buffer (25 x concentrate) (20 ml/bottle) --- Wash away unbound or free substances.
- One vial TMB Substrate (10 ml/bottle) --- Act as the chromogenic agent. TMB interacts with HRP, eliciting the solution turns blue.
- One vial Stop Solution (10 ml/bottle) --- Stop the color reaction. The solution color immediately turns from blue to yellow.
- Four Adhesive Strips (For 96 wells) --- Cover the microplate when incubation.
