Ultrasensitive Immunoassay for Simian Immunodeficiency Virus p27.

Although effective for suppressing viral replication, combination antiretroviral treatment (cART) does not represent definitive therapy for HIV infection due to persistence of replication-competent viral reservoirs. The advent of effective cART regimens for simian immunodeficiency virus (SIV)-infected nonhuman primates (NHP) has enabled the development of relevant models for studying viral reservoirs and intervention strategies targeting them. Viral reservoir measurements are crucial for such studies but are problematic.
