Activin A ELISA Kit

  • Created on the 6 February, 2017.


Human activin A ELISA kit is a reliable quantitative procedure for measuring bone activin-A in human serum, cell culture supernatant, tissue lysates and body fluids. This assay has a minimum sensitivity detection limit of < 12.0 pg/ml.


Activin A is a 14kDa beta-A homodimer, a cytokine that is member of the transforming growth factor-beta super family. It is predominately locally expressed by mesenchymal component in hemopoietic micro-environment. The expression of activin A can be regulated by a number of different cytokines at the mRNA level, in addition there are also several inhibitory molecules which are involved in tightly controlling the biological activity of this protein.

Inhibins and activins can modulate the growth and differentiation of many cell types, they function in opposing actions inhibit (inhibins) and activate (activin) the secretion of follitropin by the pituitary gland. Inhibins and activins are both important in the regulation a many diverse functions such as; erythroid differentiation, embryonic axial development, insulin secretion, bone growth, gonadal hormone secretion, germ cell development and maturation, nerve cell survival, pituitary and hypothalamic hormone secretion and embryonic axial development. The standard product which is used in the following activin A ELISA kit is recombinant activin A that is composed of two single chains made up of 116 amino acids having a molecular mass of 26KDa.


The minimum sensitivity detection limit of activin-A using current human activin A ELISA kit was approximately < 12.0 pg/ml. The dynamic assay range for this assay is 62.5 – 4000.0 pg/ml.

Your secretory IgA ELISA kit gave good results and I was also really impressed with how quickly we received it.

It is refreshing to know that you have a technical team that is very knowledgeable. I have already recommended your company to other researchers in our department.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA kit performed well and I was happy with the results that were generated.

I carried out a pilot study comparing the performance of many ELISA kits from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.

You are my first point of contact when I am looking to purchase ELISA kits. You have such an easy and simple system, yet it is very effective.
