HS024 TFA is a peptide antagonist of melanocortin receptors with high affinity for the human melanocortin-4 receptor (MC4R). HS024 TFA blocks α-MSH (HY-P0252)-induced cAMP accumulation and MC4 receptor signaling. HS024 TFA induces dose-dependent feeding stimulation without affecting anxiety-related behavior or locomotor activity. HS024 TFA can be used in research related to MC4 receptor-mediated diseases, such as eating disorders.

All Melanocortin Receptor Isoforms :

In Vitro

HS024 TFA is a selective MC4 receptor antagonist with a K_i of 0.29 nM in COS-1 cells expressing the human MC4 receptor^[1].
HS024 TFA blocks intracellular cAMP accumulation triggered by α-MSH (HY-P0252) in COS-1 cells expressing human MC1, MC3, MC4, and MC5 receptors^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

HS024 (0.1-1.0 nmol; i.c.v.; single injection on each test day; repeated every three days) TFA induces a dose-dependent increase in food intake in free-feeding Wistar rats^[1].
HS024 (0.02-0.1 nmol; i.c.v.; single injection 20 min before testing) TFA does not alter exploratory/locomotor activity in the elevated plus maze or open field^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
