Partial purification of native HIV transmembrane protein gp41: generation of polyclonal and monoclonal antibodies.

abstract：:Cyanovirin-N (CV-N), an 11-kDa cyanobacterial protein, potently inactivates diverse strains of HIV-1, HIV-2, and simian immunodeficiency virus (SIV) and also prevents virus-to-cell fusion, virus entry, and infection of cells in vitro. These properties make CV-N an attractive candidate for use as a topical microbicide ...
