Endothelin research reagents

Endothelin-1, -2 and -3 are 21-residue peptides held in a rigid fold by two disulphide bridges, and ET-1 remains the most potent vasoconstrictor described. They are produced from big-endothelin precursors by endothelin-converting enzyme, so the big-ET fragments are used as substrates in processing assays while the mature peptides and ETA/ETB receptor-domain sequences are used in binding and vascular-tone work. The sarafotoxins, structurally related snake-venom peptides, are studied as receptor probes alongside them.

This page lists all 116 Endothelin entries in the reference catalog — 43 peptides, 20 labeled antibodies, 19 assay kits, 18 antibodies and 16 labeled peptides, across bovine, canine, human, monkey, mouse, porcine, rabbit and rat sequences. Reference prices run $51 – $1,159; everything is available to order by catalog number.

Ordering Endothelin reference material

Every row above is a reference listing, not a stocked storefront line: the catalog number is the reference we quote against, and the price shown is the reference price for the size in the detail column. Send the catalog number and we will confirm current availability, lead time and the exact size before anything is ordered. If a sequence, species or label you need is not in this family, ask — our reference network is wider than this catalog.

Endothelin material listed here is laboratory research material. It is not a drug, supplement or consumer product, and nothing on this page describes a therapeutic use.
