Recombinant monoclonal antibody to SEB. Manufactured using AbAb’s Recombinant Platform with variable regions (i.e. specificity) from the hybridoma 14G8.
UniProt Accession Number of Target Protein: P01552
Alternative Name(s) of Target: Staphylococcal enterotoxin B; Enterotoxin type B; entB
Immunogen: The original antibody was generated by immunizing BALB/c mice with full-length staphylococcal enterotoxin B (SEB).
Specificity: This antibody binds a conformational epitope near the C terminal end of the Staphylococcal enterotoxin B. This antibody is suspected to interact with residues 135-R, 137-F, 186-Y, 188-K, 231-E, 233-Y, and 235, 236-T.
Application Notes: This antibody in combination with 6D3 and 20B1 can be used to detect Staphylococcal enterotoxin B (SEB) in a sample using capture ELISA. This antibody is capable of detecting SEB in a western blot assay but not staphylococcal enterotoxin A (SEA) or toxic shock syndrome toxin 1 (TSST-1). 14G8 demonstrated comparable level of inhibition of SEB incuded T cell-proliferation in human T-cells from a normal donor. 14G8 also caused inhibition of cytokine induction in treated T-cells as they produced less IFN-gamma and IL-2. It was reported that 14G8 alone did not provide any protection against SEB induced lethal shock (SEBILS) in BALB/c mice and HLA-DR3 transgenic mouse model. However, when used in combination with mAb 6D3 or 20B1 it showed better results (PMID: 21233204).
