Abstract
Interferon alpha 2b (IFN?-2b) is a critical therapeutic protein with immunomodulatory properties, widely used in the treatment of various diseases, including viral infections and cancer. This study presents a comprehensive methodology for the cloning and characterization of the IFN?-2b gene, including the identification of point mutations, followed by expression in Bacillus subtilis. The research begins with gene isolation, primer design, RNA extraction, cDNA synthesis, and PCR amplification. Cloning into a T/A vector and subsequent sequencing reveal point mutations within the gene. The transformed construct is expressed in Bacillus subtilis, and the resulting protein is analyzed using SDS-PAGE. The identification of point mutations and successful protein expression in Bacillus subtilis. This study provides valuable insights into the IFN?-2b gene and its potential applications.
