Calcitonin (rat) 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.

Aflatoxin B2 is a major naturally produced aflatoxin. Aflatoxin B2 is a mycotoxin produced by the fungi Aspergillus flavus and Aspergillus parasiticus.The level of toxicity associated with Aflatoxin is AflatoxinB1>Aflatoxin M1>Aflatoxin G1>Aflatoxin B2>Aflatoxin M2>Aflatoxin G2.

Cyanidin 3-arabinoside is a selective and reversible protein tyrosine phosphatase 1B (PTP1B) inhibitor, with an IC50 of 8.91 μM. Cyanidin 3-arabinoside is potential for the research of type 2 diabetes.
