• To establish a streamlined process for antibody screening and validation.

Main Methods:

• Application of antibody phage display technology to ribonucleoprotein (RNP) complexes as antigens.
• Development of a simple and efficient screening protocol for RNP-specific antibodies.
• Implementation of a method to resolve issues with amber stop codons in phage display clones.
• Validation of generated antibodies using Enzyme-Linked Immunosorbent Assay (ELISA) and Western blot analysis.

Main Results:

• Successful generation of antibodies specific to large intact ribonucleoprotein (RNP) complexes.
• Production of antibodies targeting individual components of RNPs.
• An efficient method was established to overcome amber stop codon challenges in phage clones.
• The developed antibodies demonstrated utility in standard immunological assays like ELISA and Western blot.

Conclusions:
