Our Abpromise guarantee covers the use of ab9071 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||Use a concentration of 1 - 10 µg/ml.
ab9071 exhibits reactivity with viral lysates by Western blot
|Radioimmunoprecipitation||Use at an assay dependent concentration. The antibody immunoprecipitates p24 protein from radiolabeled infected cell extracts.|
|ELISA||Use at an assay dependent concentration.
ab9071 is especially useful as a solid phase adsorbent or detector antibody in an ELISA format.
|ICC/IF||Use a concentration of 1 - 10 µg/ml. Exhibits reactivity with HIV-1 infected cultures using indirect immunofluorescence.|
|Sandwich ELISA||Use at an assay dependent concentration. Can be paired for Sandwich ELISA with Mouse monoclonal [39/6.14] to HIV1 p24 (ab9072).|
RelevanceHIV1 performs highly complex orchestrated tasks during the assembly, budding, maturation and infection stages of the viral replication cycle. During viral assembly, the proteins form membrane associations and self-associations that ultimately result in budding of an immature virion from the infected cell. Gag precursors also function during viral assembly to selectively bind and package two plus strands of genomic RNA. Capsid protein p24 probably forms the conical core of the virus that encapsulates the genomic RNA-nucleocapsid complex.

Immunoblot analysis of viral proteins in HEK293-derived cells transiently transfected with the proviral plasmid, pNL4-3. EV or POM121C (614–987) cells were transfected with 1.0 μg of pNL4-3. The cells were harvested 48 h post-transfection and lysates were subjected to immnoblot analyses with anti-HIV-1 p24 (top panel; the upper arrow indicated precursor Gag [PrGag], the lower arrow indicated CA), anti-HA (middle panel) and anti-CYPA (bottom panel). One representative set of results from three independent experiments is shown.
Whole-cell lysates were prepared as follows: cells were washed twice with phosphate-buffered saline (PBS) (-), suspended in PBS(-) (500 μl per 1 × 107 cells) and mixed with an equal volume of 2 × sample buffer (4% sodium dodecyl sulfate, 125 mM Tris-HCl, pH 6.8, 10% 2-mercaptoethanol, 10% glycerol, and 0.002% bromphenol blue). Proteins were solubilized by heating for 5 min at 95°C. Samples were subjected to SDS-PAGE, transferred to PVDF membranes, and reacted with mouse monoclonal antibody to HIV-1 p24 (#ab9071, Abcam, Inc., Cambridge, MA), or rabbit polyclonal antibody to CYPA (#BML-SA296, Enzo Life Sciences, Inc., Farmingdale, NY). Membranes were then incubated with horseradish peroxidase-conjugated secondary antibody (#NA934 for anti-rabbit IgG, #NA931 for ant-mouse IgG, #NA933 for anti-human IgG, Amersham Biosciences, Piscataway, NJ), and proteins were visualized by Western Lightning Plus-ECL (PerkinElmer, Waltham, MA) or enhanced chemiluminescence (Pierce Biotechnology, Rockford, IL).
