Application ELISA
Kit Detection Method Colorimetric, OD450 nm
Kit Duration ~ 3 Hours
Kit Principle Aviva Systems Biology INHBA ELISA Kit (Rat) (OKBB00125) is based on standard sandwich enzyme-linked immune-sorbent assay technology. An antibody specific for INHBA has been pre-coated onto 96-wellplate (12 x 8 Well Strips). Standards (CHO, G311-S426) and test samples are added to the wells, incubated and removed. A biotinylated detector antibody specific for INHBA is added, incubated and followed by washing. Avidin-Biotin-Peroxidase Complex is then added, incubated and unbound conjugate is washed away. An enzymatic reaction is visualized through the addition of TMB substrate which is catalyzed by HRP to produce a blue color product that changes yellow after adding acidic stop solution. The density of yellow coloration read by absorbance at 450 nm and is quantitatively proportional to the amount of sample Rat INHBA captured in well.

:: Principle: Aviva’s rat Activin A ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. Rat Activin A specific-specific monoclonal antibodies were precoated onto 96-well plates. The rat specific detection monoclonal antibodies were biotinylated. The test samples and biotinylated detection antibodies were added to the wells subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the rat Activin A amount of sample captured in plate.
:: Notes: 1. To inspect the validity of experiment operation and the appropriateness of sample dilution proportion, pilot
experiment using standards and a small number of samples is recommended.
2. The TMB Color Developing agent is colorless and transparent before using, contact us freely if it is not the case.
3. Before using the Kit, spin tubes and bring down all components to the bottom of tubes.
4. Duplicate well assay is recommended for both standard and sample testing.
5. Don’t let 96-well plate dry, for dry plate will inactivate active components on plate.
6. Don’t reuse tips and tubes to avoid cross contamination.
7. To avoid to use the reagents from different batches together.
8. In order to avoid marginal effect of plate incubation due to temperature difference ( reaction may be stronger in the
marginal wells), it is suggested that the diluted ABC and TMB solution will be pre-warmed in 37C for 30 min before
using.
Background: Activin A is a homodimer of 14kDa beta-A. Activin A, a cytokine member of the transforming growth factor-beta superfamily, is expressed locally by the mesenchymal component of the hemopoietic microenvironment. Its expression is regulated on the mRNA level by different cytokines, and the biological activity of the protein is tightly controlled by several inhibitory molecules.1 Inhibins and activins are members of the transforming growth factor beta superfamily and are known to modulate the growth and differentiation of several cell types.2 Inhibins and activins inhibit and activate, respectively, the secretion of follitropin by the pituitary gland. Inhibins/activins are involved in regulating a number of diverse functions such as hypothalamic and pituitary hormone secretion, gonadal hormone secretion, germ cell development and maturation, erythroid differentiation, insulin secretion, nerve cell survival, embryonic axial development or bone growth, depending on their subunit composition. Inhibins appear to oppose the functions of activins. The standard product used in this kit is recombinant Activin A, which is composed of two single chains of 116 amino acids with the molecular mass of 26KDa.
