Activin A (ACVA) ELISA Kit

Antigen: Activin A (ACVA)

Reactivity: Rat (Rattus)

Application: ELISA

Catalog no.: ABIN411256

Additional Information

Characteristics: For quantitative detection of rat Activin A in sera, body fluids, tissue lysates or cell culture supernates.

Alternative name: Activin A

Description: 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.

Specificity: No detectable cross-reactivity with any other cytokine.

Sensitivity: Sensitivity: < 12pg/ml. Range: 62.5pg/ml-4000pg/ml

Application Details

Principle: This 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 (clone No. 69403) 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.

Application Notes: Before using Kit, spin tubes and bring down all components to bottom of tube. Duplicate well assay was recommended for both standard and sample testing. Don
