(Tyr1)-pTH (1-34) (human) is a polypeptide that can be found by peptide screening. Peptide screening is a research tool that pools active peptides primarily by immunoassay. Peptide screening can be used for protein interaction, functional analysis, epitope screening, especially in the field of agent research and development.

This peptide is a TRP-tyrosinase-related protein. Its immunization results in effective induction of antitumor immunity.

Methyl retinoate (Retinoic acid, methyl ester) induces aseptic inflammation at the site of administration in in vivo experiments, which causes an increase in the number of leukocytes in the blood and a decrease in the levels of red blood cells and Hb.Methyl retinoate promotes spontaneous leukemia.Methyl retinoate can be Used in the treatment of gastric hypertrophy and ulcers due to vitamin A deficiency.
