产品描述
The Human α-Smooth muscle actin (α-SMA) ELISA Kit can quantitatively detect the content of α-SMA in human serum, urine, or tissue homogenates. This assay employs the sandwich ELISA mechanism and enzyme-substrate chromogenic reaction to achieve the measurement. The solution develops in proportion to the amount of α-SMA in the sample. And the color intensity can be measured at 450 nm through a microplate reader. The kit has undergone rigorous quality validation in many aspects, including sensitivity, specificity, precision, recovery, linearity, and consistency between batches.
Due to its absence in fibroblasts of normal hearts, α-SMA is the definitive marker for the activated myofibroblasts in hypertrophic and fibrotic hearts and heart failure in humans. α-SMA is also considered not only a mediator of traction forces in contractile myofibroblasts, but also a component of the global mechanotransduction system. The study of Arti V.Shinde etc. has shown that α-SMA knockdown attenuates serum-induced contraction of fibroblast-populated collagen pads. And α-SMA overexpression reduces pad contraction, attenuating fibroblast proliferative activity.

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