Detection of p56 in grouper (Chromileptes alvitelis) by giving peridinin chlorophyll protein (PCP) using immunohistochemical

P56 protein is a protein molecule that has immune activity, which inhibits the initiation of the translation of viral genetic material. The administration of Peridinin Chlorophyl Protein (PCP) is thought to be able to initiate the release of the P56 molecule, detection of protein 56 expression can be carried out using immunohistochemical techniques, namely painting by involving labeled antibodies. This study looked qualitatively at P56 expression in the brain tissue and eyes of grouper rats that had been given Peridinin Chlorophyl Protein (PCP) and infected with Viral Neveous Necrosis (VNN). Based on the results of painting anti-P56 antibodies, it can be seen that P56 is expressed in tissue of fish organs that have been given PCP, as well as in fish exposed to VNN.
