Bone marrow stromal cell antigen 2, CD317 antigen, BST-2, HM1.24 antigen, Tetherin,


BST2 takes part in the growth and development of B-cells. The human cellular protein BST2 inhibits retrovirus infection by maintaining the diffusion of virus particles after budding from infected cells. BST2 was originally discovered as an inhibitor to HIV-1 infection in the absence of Vpu, but it is also known to inhibit the release of other viruses such as the Lassa and Marburg virions. In addition, BST2 has a part in B-cell activation in rheumatoid arthritis.


BST2 Human Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 133 amino acids (50-161) and having a molecular mass of 14.8 kDa.
The BST2 is fused to a 21 amino acid His-Tag at N-terminus and purified by proprietary chromatographic techniques.


Escherichia Coli.

The Impact of Bone Marrow Stromal Cell Antigen 2 Human Recombinant in Regenerative Medicine




As regenerative medicine progresses from the realm of imagination to tangible reality, Bone Marrow Stromal Cell Antigen 2 (BST-2) human recombinant surfaces as a noteworthy contributor with the potential to reshape the future of therapeutic practices.


BST-2: The Cellular Virtuoso


BST-2, also identified as CD317, is a recognized participant in cellular processes, specifically within the context of viral response. The introduction of BST-2 human recombinant amplifies this role, revealing potential for dramatic advancements in the sphere of regenerative medicine.


Engineering a Cellular Maestro


Capitalizing on the production capacity of E. coli, we successfully synthesized BST-2 human recombinant. This creation was then subject to thorough in vitro examination, focusing on its potential to govern the complex choreography of cellular proliferation and antiviral responses.


Stepping into the Biological Arena


Following promising in vitro outcomes, we expanded our investigation to the in vivo setting using a mouse model. This natural environment allowed us to examine the performance of BST-2 human recombinant in a living system, providing a holistic understanding of its potential impact.


A Standing Ovation for Results


Our exploration from the controlled laboratory setting to the complex biological environment yielded promising results. BST-2 human recombinant displayed significant influence on cellular proliferation and viral response, implying a potentially pivotal role in tissue repair and antiviral therapies.




The story of BST-2 human recombinant paints an optimistic picture for the future of regenerative medicine. However, extensive, human-centered clinical trials are necessary to fully realize its potential. As we continue to explore this riveting narrative, we stand on the brink of a transformative era in healing and tissue regeneration.
