Fusion glycoprotein F0/F Protein, HRSV (AFX60213, sf9, His)

F0/F is a class of viral fusion proteins that, as an inactive precursor, are cleaved by a furfurin-like protease at two sites to produce mature F1 and F2 fusion glycoproteins.The F protein can mediate cell-cell fusion, lead to syncytial formation, and trigger p53-dependent apoptosis in the later stages of infection.Fusion glycoprotein F0/F Protein, HRSV (AFX60213, sf9, His) is the recombinant Virus-derived Fusion glycoprotein F0/F protein, expressed by Sf9 insect cells , with C-His labeled tag.

F0/F is a class of viral fusion proteins that, as an inactive precursor, are cleaved by a furfurin-like protease at two sites to produce mature F1 and F2 fusion glycoproteins. The F1-F2 trimer (F protein) plays a dual role, helping to attach to host cells by binding to host heparin sulfate, and facilitating entry into host cells by interacting with host IGFR1. F protein can mediate cell-cell fusion, leading to syncytial formation, and F protein may trigger p53-dependent apoptosis in the late stage of infection^[1][2][3].

Approximately 66.9 kDa & 57.9 kDa,based on SDS-PAGE under non-reduced conditions.

≥ 90%, as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.2 μm filtered solution of 20mM PB, 300mM NaCl, 10% Glycerol, pH7.5, 22.5% Trehalose.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
