(Tyr27)-α-CGRP (27-37) (canine, mouse, 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.

Anaritide is a synthetic form of atrial natriuretic peptide (ANP) composed of 25 amino acids. Anaritide increases glomerular filtration rate by dilating into and contracting out the bulbar arterioles. Anaritide can be used to study the effects on patients with acute tubular necrosis, particularly in improving dialysis free survival.

Levothyroxine, the major hormone derived from the thyroid gland, is the agonist of Thyroid hormone receptor alpha and beta.evothyroxine (L-T(4))can upregulate the expression of P-gp mRNA and protein in LS180 cells, but only L-T(4) and L-T(3) can produce the same effect in Caco-2 cells, which are relatively lacking in PXR.
