[Use of agarose for isolating influenza virus proteins retaining a high immunogenicity]

Area of Science:

• Virology
• Immunology
• Biochemistry

Background:

• Influenza virus characterization requires efficient separation and protein analysis.
• Existing methods for influenza virus separation may have limitations in accessibility or efficacy.

Purpose of the Study:

• To modify and optimize a method for influenza virus separation using agarose.
• To evaluate the utility of domestically produced agarose and Difco agar for this separation.
• To isolate key influenza virus proteins (RNP and M) and develop specific antibodies.

Main Methods:

• Modification of an existing agarose gel electrophoresis technique for influenza virus separation.
• Isolation and purification of Ribonucleoprotein (RNP) and Matrix (M) proteins from influenza virus.
• Development and characterization of polyclonal antisera against isolated RNP and M proteins.
• Validation of antibody activity using Enzyme-Linked Immunosorbent Assay (ELISA) and Radioimmunoassay (RIA).

Main Results:

• The modified agarose separation method proved effective for influenza virus isolation.
• Both national agarose and Difco agar were suitable for the separation process.
• Highly active antisera against RNP and M proteins were successfully prepared.
• The developed antibodies demonstrated high efficacy in both ELISA and RIA applications.

Conclusions:

• The optimized agarose separation technique enhances influenza virus isolation capabilities.
• The availability of specific, highly active anti-RNP and anti-M sera facilitates improved influenza virus detection and characterization.
• This work provides valuable tools for influenza research and diagnostics.
