| pubmed-article:20591456 | pubmed:abstractText | In this paper, the cDNA encoding the extracellular soluble domain of rabbit BAFF (rsBAFF) was subcloned into the pET28a vector and the recombinant rsBAFF protein was solubly produced in Escherichia coli. Recombinant rsBAFF protein of 17.1kDa was then purified to a purity of 95% by using Ni(2+)-IDA resin. In vitro, purified rsBAFF protein was able to promote the survival/proliferation of B-lymphocytes of rabbits, mice and humans in the presence of anti-IgM antibodies. These findings indicate that the recombinant rsBAFF produced in E. coli have the bioactivity, and functional cross-reactivity occurs between rabbit and other mammalians BAFF proteins. | lld:pubmed |
