Physical Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.


Lyophilized from 1mg/ml solution in 0.05M Tris-HCl buffer pH 7.4.


It is recommended to reconstitute the lyophilized Activin B in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.


Lyophilized Activin B although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Activin B should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.


Greater than 97.0% as determined by Analysis by SDS-PAGE.

Amino acid sequence


Biological Activity

The biological activity of Activin B is measured by its ability to inhibit mouse plasmacytoma cell line (MPC-11) cells proliferation. EC50 <5ng/ml is required to stimulate a half-maximal response at cytokine saturation. Note: Since applications vary, each investigator should titrate the reagent to obtain optimal results.

An Investigation into the Functional Roles and Therapeutic Potential of Activin-B Human Recombinant, Active 


1. Abstract


Activin-B Human Recombinant, Active, also referred to as beta-2, Activin beta-B chain, or MGC157939, is a crucial component of the Transforming Growth Factor-beta (TGF-beta) superfamily. The multifaceted nature of this protein implicates it in numerous physiological processes. This paper delves into the bioactivity of Activin-B, exploring its role in cellular proliferation, differentiation, apoptosis, and its potential for therapeutic applications, especially in the realms of regenerative medicine, reproductive health, and cancer therapy.


2. Introduction


The TGF-beta superfamily, of which Activin-B is a member, is renowned for its far-reaching implications in cell and developmental biology. This superfamily boasts members that control cell growth, differentiation, and apoptosis, thus playing vital roles in organogenesis, bone growth, and reproductive functions. This research paper aims to shed light on the characteristics and potential therapeutic applications of Activin-B.


3. Structure and Synthesis of Activin-B


Activin-B is a dimeric protein, composed of two identical beta-B chains. This homodimer undergoes multiple stages of synthesis, starting as a precursor protein, which then experiences proteolytic processing to eventually form the mature peptide. It is this coordinated activity of various enzymes and molecular chaperones that ensure the accurate biosynthesis of Activin-B.


4. Biological Functions of Activin-B


Activin-B's roles extend from embryogenesis and organogenesis to the modulation of reproductive functions. Its influence over cellular proliferation, differentiation, and apoptosis has significant repercussions in physiological and pathological scenarios. Its regulatory functions also encompass immunomodulation and wound healing, underpinning its extensive biological reach.


5. Activin-B in Regenerative Medicine


Regenerative medicine's primary focus is the repair and regeneration of tissues, and it is here that the potential of Activin-B shines. The protein's capacity to regulate cellular processes positions it as a possible agent in tissue repair, making it an intriguing research topic for therapeutic applications in regenerative medicine.


6. Activin-B and Reproductive Health


Activin-B’s role in reproductive health is undeniable, having been implicated in follicular development, ovulation, and pregnancy maintenance. Its potent influence on reproductive functions indicates the possibility of its use in the treatment of reproductive disorders, providing a potential pathway for further therapeutic development.


7. Activin-B in Cancer


Recent research has connected the deregulation of Activin-B to various types of cancer. Deciphering the mechanisms through which Activin-B affects cancer cell proliferation and survival could open up new avenues for targeted cancer therapy. This critical linkage emphasizes the need for comprehensive studies on Activin-B's role in oncogenesis.


8. Conclusion and Future Perspectives


Our understanding of Activin-B's biological functions has grown immensely, but many mysteries remain. The continued exploration of the molecular mechanisms through which Activin-B operates will undoubtedly yield more insights into its potential therapeutic uses, guiding the development of new treatments for a myriad of diseases.
