Simian immunodeficiency virus, SIV, is a retrovirusthat is found in strains, having the HIV-1and HIV-2specific strains that infect humans. SIV strains may cause an AIDS-like immune deficiency known as SAIDS (simian acquired immunodeficiency syndrome) if they cross species boundaries. HIV-2 is more similar to SIV strains than to HIV-1, suggesting for the first time the simian origin of HIV. HIV-2 is derived from the SIV strain found in sooty mangabeys whereas HIV-1, the predominant virus found in humans, is derived from SIV strains infecting chimpanzees.
Recombinant SIV p55 although stable at 4℃ for 3 weeks, should be stored desiccated below -18℃. For long term storage it is recommended to add a carrier protein (0.1% HSA).
Please avoid freeze-thaw cycles.
