  2. Western blot - Wikipedia

    en.wikipedia.org/wiki/Western_blot

    The confirmatory HIV test employs a western blot to detect anti-HIV antibody in a human serum sample. Proteins from known HIV-infected cells are separated and blotted on a membrane as above. Then, the serum to be tested is applied in the primary antibody incubation step; free antibody is washed away, and a secondary anti-human antibody linked ...

    In a generally healthy low-risk population, indeterminate results on western blot occur on the order of 1 in 5,000 patients. [16] However, for those individuals who have had high-risk exposures to individuals where HIV-2 is most prevalent, Western Africa, an inconclusive western blot test may prove infection with HIV-2. [17]

    en.wikipedia.org/wiki/Lysis_buffer

    A lysis buffer is a buffer solution used for the purpose of breaking open cells for use in molecular biology experiments that analyze the labile macromolecules of the cells (e.g. western blot for protein, or for DNA extraction).

  5. Viral load monitoring for HIV - Wikipedia

    en.wikipedia.org/wiki/Viral_load_monitoring_for_HIV

    Viral load monitoring for HIV complements the CD4 count, which is another sort of test associated with monitoring HIV. Confusion about when to take a CD4 test is common. [1] The results of a viral load test help determine when a CD4 count is indicated. [1] CD4 cells are the primary target of HIV. A CD4 test quantifies Helper T cells and is ...

    Thus, the antibodies used in RPMA must be carefully validated for specificity and performance against cell lysates by western blot. [ 1 ] [ 7 ] RPMA has various uses such as quantitative analysis of protein expression in cancer cells, body fluids or tissues for biomarker profiling, cell signaling analysis and clinical prognosis, diagnosis or ...

  7. Pathophysiology of HIV/AIDS - Wikipedia

    en.wikipedia.org/wiki/Pathophysiology_of_HIV/AIDS

    A good CD8 + T cell response has been linked to slower disease progression and a better prognosis, though it does not eliminate the virus. [3] During the acute phase, HIV-induced cell lysis and killing of infected cells by cytotoxic T cells accounts for CD4 + T cell depletion, although apoptosis may also be a factor.
