简介
The BST2 protein is an IFN-induced antiviral factor that inhibits mammalian enveloped viruses by tethering viral particles to infected cell membranes. BST2 acts as a physical tether connecting virions, limiting their release and spread. BST2 Protein, Mouse (HEK293, hFc) is the recombinant mouse-derived BST2 protein, expressed by HEK293 , with N-hFc labeled tag.

Stability Test
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.
-
Storage & Shelf Life

Protein Description
BST-2, also known as bone marrow stromal antigen 1 (BSA1) or tetherin, is a type II transmembrane protein that plays a critical role in the host immune response against viral infections. It was initially discovered for its ability to restrict the release of enveloped viruses, such as HIV, from infected cells, effectively tethering them to the cellular membrane. This pioneering discovery highlighted the protein's importance in the innate immune defense, intriguingly positioning it as a potential therapeutic target for antiviral strategies. Moreover, BST-2's expression is regulated by various cytokines and can be modulated by different pathogens, including certain viruses that exploit it for their replication. Research into BST-2 has expanded to explore its diverse roles beyond antiviral responses, revealing associations with cancer metastasis and immune regulation. Understanding the molecular mechanisms underlying BST-2 function and its interactions with viral components has become a significant area of interest, as it could lead to novel approaches for enhancing immune responses or developing antiviral therapies. As such, BST-2 recombinant proteins are increasingly utilized in basic and applied research to dissect its mechanisms of action and assess its potential as a biomarker or therapeutic target in various disease contexts, paving the way for innovative strategies in both virology and oncology.
