What BQ-123 is studied for

  • Vascular reactivity in aortic ring and mesenteric bed preparations
  • Renin–angiotensin–aldosterone system (RAAS) mechanistic studies
  • Natriuretic and diuretic pathway characterization
  • Cardiac remodeling and hypertrophy models

Mechanism of action

BQ-123 sits within the Cardiovascular research class (CPC reference ENDT-008). Cardiovascular peptides act on GPCRs and receptor systems in vascular smooth muscle, endothelium, and cardiac myocytes — modulating vasoconstriction, natriuresis, RAAS signaling, or ionotropic responses. Effects are typically measured in isolated vessel, Langendorff heart, or receptor-transfected cell assays.</ Investigators typically incorporate BQ-123 as a reference standard, tool ligand, or substrate in the assay contexts listed above. Radioligand-binding, IP-1 / cAMP HTRF, and organ-bath tension recordings are the standard readouts.

Frequently asked questions

What is BQ-123?

BQ-123 (CPC catalog code ENDT-008) is a synthetic cardiovascular research peptide in the cardiovascular category. It is provided as a lyophilized ~1 mg vial for in-vitro research use only.

What is BQ-123 studied for?

Published and internal research programs use BQ-123 as a reference standard in cardiovascular workflows — for example, vascular reactivity in aortic ring and mesenteric bed preparations and renin–angiotensin–aldosterone system (raas) mechanistic studies. Human clinical evidence is not established.

Is BQ-123 FDA-approved for human use?

No. BQ-123 is a research-grade reference peptide and is not approved by the FDA or any national regulator for human or veterinary therapeutic use. It is offered exclusively for in-vitro laboratory research and does not ship to the United States for consumer use.

How is BQ-123 typically used in the lab?

In a cardiovascular workflow, BQ-123 is reconstituted in sterile buffer or DMSO (solubility-dependent) and applied in the researcher's chosen assay format. Radioligand-binding, IP-1 / cAMP HTRF, and organ-bath tension recordings are the standard readouts.

How should BQ-123 be stored?

Stable lyophilized at −20 °C for ≥24 months. Reconstitute in normal saline or PBS. Follow your institution's standard operating procedures for handling synthetic peptides.

Where does the BQ-123 product page point to?

This kindr reference page mirrors CPC Scientific's catalog metadata for ENDT-008. The upstream reference sheet — including sequence, purity, MW, and application notes where published — is linked from the buy panel. All orders placed on kindr Peptides ship internationally under research-use terms only.

What quality specifications apply to BQ-123?

Research-grade peptides in the CPC catalog are synthesized by solid-phase peptide synthesis (SPPS), purified by preparative RP-HPLC, and characterized by analytical HPLC and mass spectrometry. Typical purity is ≥95%; certificate of analysis is available on request.
