| Description |
The Human Gelsolin (GSN) ELISA Kit quantifies GSN in human serum, plasma, cell culture supernates, or tissue homogenates. It is not intended for diagnostic use. This assay kit was designed and optimized for metabolic research use in humans. The kit has undergone rigorous quality control in multiple parameters, including sensitivity, specificity, precision, linearity, recovery, and inter-batch difference. Refer to the product instructions for more details. This assay employs the quantitative sandwich enzyme immunoassay technique, in which GSN in the samples or standards are sandwiched between pre-coated GSN antibody and Biotin-conjugated GSN antibody. HRP-avidin is then added into the wells. Following a wash to remove any unbound reagent, the TMB substrate solution is added to the wells and color develops in proportion to the amount of GSN bound in the initial step. The color development is stopped upon adding the stop solution, and the intensity of the color is measured at 450 nm via a... Read more |

| Linearity |
| To assess the linearity of the assay, samples were spiked with high concentrations of human gelsolin 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 GSN 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 GSN 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-antibodyDiluent (15 ml/bottle) ---Dilute the Biotin-antibody.
- One vial HRP-avidin Diluent (15 ml/bottle) ---Dilute the HRP-avidin solution.
