catnap_antibody_info ~230 tokens
Metadata for an HIV antibody in LANL CATNAP: which region of the virus it binds (CD4 binding site, V3 glycan, MPER, …), its aliases, the paper that isolated it with PubMed id, light chain type, ADCC activity, and its mean panel IC50 with the number of viruses tested. Answers "what does PGT121 bind",
catnap_search_neutralization ~326 tokens
HIV broadly neutralizing antibody POTENCY: IC50/IC80/ID50 measurements for an antibody across viral strains, or for a strain across antibodies, from LANL CATNAP. Answers "how potent is VRC01 against this strain", "which antibodies neutralize CNE8", "compare this antibody's panel across subtypes". Ev
immunology_search ~481 tokens
Search the LANL HIV Molecular Immunology Database for T-cell epitopes (CTL/CD8+ or T-helper/CD4+) or antibody binding sites — a different question from catnap_search_neutralization: this is about WHERE on the virus an immune response targets and WHICH HLA restricts it, not how potently an antibody n
