The cDNA sequence encoding Hc-CATH and native Hc-CATH expression in snake tissues. A, the nucleotide sequence encoding Hc-CATH and the deduced amino acid sequence of Hc-CATH precursor. The putative mature peptide is boxed. The stop codon is indicated by an asterisk (*). B, the native Hc-CATH expression in different snake tissues. The synthetic Hc-CATH was used as antigen to immunize mice, and the polyclonal antibody of Hc-CATH was prepared. Western blot was performed using the prepared polyclonal antibody, and β-actin was used as control.
