Amino Acid Sequence

Glp-His-Trp-Ser-Tyr-Trp-Leu-Arg-Pro-Gly-NH2

Application

[D-Trp6]-LH-RH (luteinizing hormone releasing hormone) has been used to study whether the (M. – X) region in electron capture dissociation provides information on amino acid composition of polypeptides. It is also used to study the effect of LH-RH on the production of progesterone (P), estradiol (E2) or human chorionic gonadotropin (hCG) by JEG-3 choriocarcinoma cells.

Biochem/physiol Actions

Potent LH-RH agonist with enhanced biological activity due to its slower rate of degradation. Like [D-Lys6]-LH-RH, the D-Trp6 analog has been shown to be effective against cancers expressing the LH-RH receptor. However, unlike the D-Lys6 analog, it is generally used in the unconjugated form.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.
