pTH (28-48) (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.

Flurocitabine HCl is a fluorinated anhydride analog of cytarabine, which is partially hydrolyzed in vivo to two active antitumor substances (arabinosyl-fluorouracil (ara-FC) and arabinosyl-fluorouracil (ara-FU)).

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.
