Human Follistatin Like Protein 1 (FSTL1) ELISA Kit
Principle of the Assay
The microtiter plate provided in this kit has been pre-coated with an antibody specific to FSTL1. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody preparation specific to FSTL1. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After the TMB substrate solution is added, only those wells that contain FSTL1, 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 FSTL1 in the samples is then determined by comparing the O.D. of the samples to the standard curve.
For Use with serum, plasma, and cell culture supernatants. For Research Use Only. Not for use in diagnostic procedures.
Target Information
Secreted glycoprotein that is involved in various physiological processes, such as angiogenesis, regulation of the immune response, cell proliferation and differentiation (PubMed:29212066, PubMed:22265692). Plays a role in the development of the central nervous system, skeletal system, lungs, and ureter (By similarity). Promotes endothelial cell survival, migration and differentiation into network structures in an AKT-dependent manner. Also promotes survival of cardiac myocytes (By similarity). Initiates various signaling cascades by activating different receptors on the cell surface such as DIP2A, TLR4 or BMP receptors (PubMed:20054002, PubMed:22265692).

Performance Characteristics
REPEATABILITY |
Intra-assay Precision (Precision within an assay): 3 samples with low, middle, and high-level FSTL1 were tested 20 times on one plate, respectively. |
SENSITIVITY | The minimum detectable dose was 14.6pg/mL. |
ASSAY RANGE | 31.2-2000pg/mL |
SPECIFICITY | This assay has high sensitivity and excellent specificity for the detection of FSTL1. No significant cross-reactivity or interference between FSTL1 and analogs was observed. Note: Limited by current skills and knowledge, it is impossible to perform all possible cross-reactivity detection tests between FSTL1 and all analogs, therefore, cross reactivity may still exist. |
