ZHEJIANG PEPTITES BIOTECH Co.,Ltd sell "Tetracosactide"

Tetracosactide Acetate (CAS 16960-16-0) has the sequence Ser-Tyr-Ser-Met-Glu-His-Phe-Arg-Trp-Gly-Lys-Pro-Val-Gly-Lys-Lys-Arg-Arg-Pro-Val-Lys-Val-Tyr-Pro, molecular formula C136H210N40O31S, and a molar mass of 2933.44 g/mol, with purity of at least 98% and impurity content no greater than 0.5%. It should be stored at 2-8C and is packed in 1g, 10g, or 50g bottles, or per customer specification. It is used to test adrenal gland function: tetracosactide, also known as cosyntropin, is a synthetic peptide identical to the 24-amino-acid N-terminal segment of adrenocorticotropic hormone (sequence SYSMEHFRWGKPVGKKRRPVKVYP). This segment, ACTH(1-24), is conserved across species and carries the biological activity that stimulates corticosteroid production in the adrenal cortex; tetracosactide reproduces all the biological activities of natural ACTH. The resulting complex is absorbed in humans over a longer period than...
