Generation of Schlafen 8-Specific Antibodies

Area of Science:

• Molecular Biology
• Immunology
• Protein Research

Background:

• Schlafen (SLFN) 8 and SLFN9 are mouse proteins with poorly defined physiological roles.
• Lack of reliable antibodies hinders the study of SLFN8 and SLFN9 functions.

Purpose of the Study:

• To develop specific antibodies for detecting Schlafen (SLFN) 8 and SLFN9 proteins.
• To enable further research into the physiological functions of SLFN8 and SLFN9.

Main Methods:

• Amino acid sequence alignment and AlphaFold modeling identified a surface-exposed peptide.
• Peptide conjugation, mouse immunization with Poly(I:C) adjuvant, and hybridoma generation.
• Antibody specificity verified using Western blotting, immunoprecipitation, immunohistochemistry, and ELISA.

Main Results:

• Successfully generated and validated anti-SLFN8 antibodies with high specificity.
• Antibodies demonstrated efficacy across various immunodetection techniques.
• Developed hybridomas secreting IgG antibodies specific to the SLFN8 peptide.

Conclusions:

• The identified peptide is highly immunogenic and elicits specific antibodies.
• The developed antibodies can distinguish between the highly similar SLFN8 and SLFN9 proteins.
• This work provides essential tools for advancing Schlafen protein research.
