Example 4
Melanocytes (B16F10 cell line) were incubated on 6-well culture plates in an incubator for 24 hours, and were treated with the peptide of the present invention with different concentrations. After the incubation for 24 hours, the cells were dissolved, and the expression of tyrosinase, which is an essential enzyme involved in melanogenesis, was observed by western blot assay using a specific antibody. The test was conducted using an anti-tyrosinase antibody (Santa Cruz Biotechnology, USA).
When melanocytes B16F10 were treated with the peptide having the amino acid sequence of SEQ ID NO: 1 or SEQ ID NO: 2 and the expression aspect of the tyrosinase protein involved in melanogenesis was observed over time, it was verified that the expression of the protein was increased compared with a control in view of the 6-hour treatment and 24-hour treatment (
