Description

Stresscopin (3-40) (Human) Trifluoroacetate Salt is a synthetic peptide fragment corresponding to the 3-40 sequence of human stresscopin, a neuropeptide involved in the body's stress response system. This high-purity reference standard is critical for research and development in neuroendocrinology and metabolic disease studies. It is primarily utilized by pharmaceutical R&D teams, academic research institutions, and diagnostic developers requiring precise and reliable bioactive peptides for assay development, receptor binding studies, and pharmacological evaluation.

Application

• Biomedical Research: Used as a reference standard in studies investigating the Urocortin/CRF receptor system, stress response pathways, and related metabolic functions.
• Assay Development: Essential for the calibration and validation of immunoassays (ELISA, RIA) and cell-based assays designed to detect or quantify stresscopin-related activity.
• Drug Discovery: Serves as a key pharmacological tool for screening and characterizing novel therapeutics targeting CRF receptors for conditions like anxiety, depression, and metabolic disorders.
• Academic & Clinical Studies: Provides a defined standard for experimental reproducibility in university labs and clinical research programs focused on neuropeptide biology.
• Quality Control: Employed by manufacturers of diagnostic kits and biopharmaceuticals as an in-house control standard to ensure batch-to-b consistency.
