General description
Fusion glycoprotein F0 (UniProt: P03420) is encoded by the F gene (Gene ID: 1494475) in Human respiratory syncytial virus A (strain A2). Human respiratory syncytial virus (hRSV) is a pneumovirus that causes significant respiratory disease in premature and full-term infants. Fusion glycoprotein F0 of RSV is synthesized with a signal peptide (aa 1-15), which is subsequently cleaved off. The inactive F0 precursor is then cleaved at two sites (aa 109-110 and 136-137) by furin-like protease to give rise to produce mature F1 and F2 fusion glycoproteins. Fusion glycoprotein F1 is a single-pass type I membrane protein that can exist as homotrimer or can form disulfide-linked heterodimer with fusion glycoprotein F2. Its N-terminus has a hydrophobic fusion peptide that inserts into the target host membrane. It is buried in the center of the trimer cavity before cleavage by host furin. The fusion glycoprotein F2 is the major determinant of the species specificity of RSV infection. Fusion protein can exist in at least 3 conformational states: pre-fusion native state, pre-hairpin intermediate state, and post-fusion hairpin state. During viral and plasma cell membrane fusion, the coiled coil regions assume a trimer-of-hairpins structure, positioning the fusion peptide in close proximity to the C-terminal region of the ectodomain. This fusion is pH independent and occurs at the plasma or endosomal membrane. The fusion protein is reported to be involved in the entry into the host cell through the interaction with host IGF-R1. This interaction activates protein kinase z that recruits host NCL/nucleolin to the apical cell surface where it can bind fusion glycoprotein F1. Later in infection, fusion protein expressed at the plasma membrane of infected cells can mediate fusion with adjacent cells to form syncytia, a cytopathic effect that could lead to tissue necrosis. Fusion protein can also trigger p53-dependent apoptosis in cells. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Biochem/physiol Actions
Clone 131-2A is a Mouse recombinant monoclonal antibody that detects fusion protein in Respiratory syncytial virus (RSV).
Physical form
Purified recombinant mouse monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.
Preparation Note
Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
