Development of monoclonal antibodies specifically recognizing the endogenous sterile alpha motif and HD domain 1 protein in porcine cell lines.

ABSTRACT: The sterile alpha motif and HD domain 1 (SAMHD1) protein has been identified as a novel innate immunity restriction factor that participates in processes crucial to the viral life cycle. In the present study, we describe a procedure to generate monoclonal antibodies (MAbs) against porcine SAMHD1 and investigate its characteristics to analyze the expression of endogenous SAMHD1. The open reading frame of porcine SAMHD1 was cloned into the prokaryotic expression vector pCold-TF DNA to construct a recombinant plasmid pcold-pSAMHD1 and induce expression of recombinant porcine SAMHD1 protein by IPTG in Escherichia coli Rosetta. The purified recombinant porcine SAMHD1 protein was used to prepare MAbs of SAMHD1. After subcloning five times hybridoma cell clones expressing SAMHD1, MAbs were genera
