Expression Host
HEK-293
Immunogen
DENV-1C19 was generated as part of a large panel of cross-neutralizing human monoclonal antibodies derived from human subjects who were confirmed to have had DENV infection by testing their serum for the presence of antibodies that neutralized each of the DENV serotypes 1.
Product Concentration
≥ 5.0 mg/ml
Endotoxin Level
< 1.0 EU/mg as determined by the LAL method
Purity
≥95% monomer by analytical SEC
Formulation
This recombinant monoclonal antibody is aseptically packaged and formulated in 0.01 M phosphate buffered saline (150 mM NaCl) PBS pH 7.2 - 7.4 with no carrier protein, potassium, calcium or preservatives added. Due to inherent biochemical properties of antibodies, certain products may be prone to precipitation over time. Precipitation may be removed by aseptic centrifugation and/or filtration.
Storage and Handling
Functional grade preclinical antibodies may be stored sterile as received at 2-8°C for up to one year. For longer term storage, aseptically aliquot in working volumes without diluting and store at ≥ -70°C. Avoid Repeated Freeze Thaw Cycles.
Country of Origin
USA
Shipping
Standard Overnight on Blue Ice.

Each investigator should determine their own optimal working dilution for specific applications. See directions on lot specific datasheets, as information may periodically change.

Description

Specificity
DENV-1C19 activity is directed against the bc loop of domain II of the E glycoprotein adjacent to the fusion loop (FL), is quaternary structure dependent, and cross-reactive against DENV-1, 2, 3, 4.

DENV-1C19 exhibited ultrahigh neutralization potency against strains corresponding to all four DENV serotypes. Fine epitope mapping studies revealed that DENV-1C19 recognizes a novel conserved site known as the bc loop (amino acids 73-79) adjacent to the fusion loop (FL) of DENV E protein in the DI/II hinge region. The bc loop residues 73, 78, and 79 have been identified as critical residues by loss-of-function binding screens. DENV-1C19 does not directly bind the FL and was unable to bind to wild-type E protein of West Nile Virus. DENV-1C19 binding was also not affected by alterations in DII-FL residues in yeast surface display or shotgun mutagenesis screenings.

DENV-1C19 neutralizes DENV effectively and competes for binding against low-potency FL antibodies, which are believed to contribute to antibody-mediated disease1. When DENV-1C19 was tested in AG129 mice for protective efficacy, it reduced the level of viremia after sublethal virus challenge for DENV-1 and -2. DENV-1C19 was able to bind to four chimeric yellow fever-dengue vaccine viruses and detected all four serotypes equally in a dot plot2.
Background
Dengue virus (DENV) is the most common insect-transmitted virus to target humans, with an estimated 390 million infections annually1. DENVs are members of the Flaviviridae family and can be divided into four closely related but antigenically distinct serotypes2. They encode a single-stranded positive sense RNA genome and display 180 copies of envelope (E) glycoprotein and premembrane/membrane (prM/M) proteins. E glycoprotein is comprised of three structural domains, DI, DII, and DIII, and exists as a homodimer in the pre-fusion state on the mature virus particle. E undergoes multiple conformation changes during maturation and fusion.
