Is a postfusion antigen a substitute for prefusion F0?
No. Prefusion and postfusion antigens represent different conformations and may expose different epitopes. Choose the antigen that matches your research objectives.
Q
What validation should be reviewed before use?
Check the selected construct’s purity and binding data, and confirm conformation-sensitive recognition with suitable controls.
Q
How should I immobilize His-tagged RSV postfusion F0?
Consider a compatible His-tag capture system, then verify antigen accessibility and background under the chosen assay conditions.
Q
Which subtype should be selected?
Choose RSV A or RSV B according to the study antigen and the specificity of the antibody or assay.
Q
Can postfusion F0 serve as an epitope comparison reagent?
It can be paired with prefusion F0 in binding studies to compare conformation-sensitive recognition.
Q
Which antibody formats are available with postfusion F0?
The portfolio includes antibodies described as specific to postfusion F0, alongside the antigen proteins.
Q
How does postfusion F0 differ from prefusion F0?
RSV F undergoes an irreversible refolding from the labile prefusion state to the more stable postfusion state.
Q
Which RSV postfusion F0 proteins are available?
Available options include His-tagged postfusion F0 proteins from RSV A strain A2 and RSV B strain B1.
