Recombinant monoclonal antibody to HIV capsid protein p24. Manufactured using AbAb’s Recombinant Platform with variable regions (i.e. specificity) from the hybridoma A10F9.
UniProt Accession Number of Target Protein: Q9DGV7
Alternative Name(s) of Target: P24; CA; Gag polyprotein
Immunogen: The original antibody was generated by immunizing mice with p24 protein.
Specificity: This antibody recognizes a continuous epitope located at α-helix 10 (residues 196 to residues 207) in the C-terminal domain of the HIV BMJ4 p24 capsid protein. The p24 capsid protein is part of the HIV-1 Gag precursor protein (p55), together with the matrix (MA/p17) and nucleocapsid (NC/p7) protein domains. p55 is the main structural HIV-1 protein, and is uniquely responsible for virion assembly within the virus life cycle.
Application Notes: The crystal structure of the Fab fragment in complex with the p24 protein from natural HIV-1 strain (BMJ4) was determined. The specificity of the antibody for the p 24 protein of BMJ4 strain was demonstrated by ELISA analysis. Immunofluorescence was performed on 293FT cells using this antibody (Gu et al., 2013; 23620741). The antibody detected CA N21C/A22C-V3 protein by Western blot analysis (Zhang et al. 2018; PMID: 30486318).

Note on publication:
The paper describes generation, structure and characterization of the antibody, which is specific for the p24 protein.
