Our core value lies in delivering high-purity BNP peptides that meet rigorous quality benchmarks, supporting accurate research outcomes and reliable formulation results.
Core Molecular Specs & Technical Index
Brain natriuretic peptide is a 32-amino acid polypeptide with a molecular weight of approximately 3.46 kDa. It plays a key role in natriuresis, vasodilation, and the renin-angiotensin-aldosterone system. For laboratory and cosmetic applications, precise technical specifications are non-negotiable.
Basic Properties
BNP is a cyclic peptide stabilized by a disulfide bridge between cysteine residues at positions 10 and 26. It is highly soluble in water and physiological buffers, with an isoelectric point (pI) around 9.5. The peptide is supplied as a lyophilized powder, typically in vials of 0.5 mg, 1 mg, or 5 mg.
Purity & Quality Index
- Purity ≥ 98% by HPLC analysis, ensuring minimal batch-to-batch variation.
- Peptide content ≥ 80% by amino acid analysis, verified through quantitative assays.
- Endotoxin levels < 1 EU/mg, suitable for cell culture and in vivo research.
- Solubility > 10 mg/mL in deionized water or PBS, with clear reconstitution.
- Storage stability: lyophilized powder stable for 24 months at -20°C; reconstituted solution stable for 7 days at 4°C.
Industry data indicates that over 70% of BNP-related research failures are attributed to peptide degradation or impurity interference. High-purity BNP (≥98%) reduces experimental variability by up to 40%, according to a 2023 survey of 150 peptide laboratories.
Manufacturing & Quality Control
Our BNP peptide is manufactured using solid-phase peptide synthesis (SPPS) with Fmoc chemistry, followed by reverse-phase HPLC purification and mass spectrometry verification. Each batch undergoes rigorous quality control to ensure consistency and reliability.
Production Process
The synthesis begins with resin-bound amino acids, sequentially coupled using HBTU activation. After cleavage and deprotection, the crude peptide is purified via preparative HPLC. The final product is lyophilized and packaged under inert argon gas to prevent oxidation.
Quality Control Measures
- HPLC purity analysis with UV detection at 214 nm and 280 nm.
- Mass spectrometry (ESI-MS or MALDI-TOF) for molecular weight confirmation.
- Amino acid analysis for peptide content and composition verification.
- Endotoxin testing using LAL assay, with results below 1 EU/mg.
- Certificate of Analysis (CoA) provided with each batch, including all test results.
Commercial Application Scenarios
BNP peptides are widely used in cosmetic formulation development, laboratory research, and bulk wholesale supply. Understanding brain natriuretic peptide elevation causes is critical for optimizing these applications.
Cosmetic Formulation
In anti-aging and skin-rejuvenating products, BNP is incorporated as a signaling peptide to support dermal matrix maintenance. Formulators require high-purity BNP to avoid unwanted side reactions and ensure batch-to-batch consistency. Typical usage levels range from 0.01% to 0.1% in serum or cream bases.
Laboratory Research
Researchers studying cardiovascular physiology, heart failure biomarkers, or natriuretic peptide pathways rely on BNP as a standard. Accurate quantification and stable peptide stocks are essential for ELISA, Western blot, and cell-based assays. Brain natriuretic peptide elevation causes are often investigated in relation to cardiac stress, renal function, and hormonal regulation.
Bulk Wholesale Usage
Bulk buyers, including contract research organizations (CROs) and peptide libraries, require large quantities of BNP with consistent purity. Our bulk supply options range from 10 mg to 100 g, with custom packaging and expedited shipping for time-sensitive projects.

Frequently Asked Questions
Q: What are the primary brain natriuretic peptide elevation causes in research settings?
A: In laboratory contexts, BNP elevation is typically induced by cardiac stress models, such as pressure overload or ischemia-reperfusion injury. It can also result from renal impairment or hormonal stimulation. Using high-purity BNP ensures that observed changes are due to experimental conditions, not peptide degradation.
Q: How does peptide purity affect the study of brain natriuretic peptide elevation causes?
A: Low-purity BNP may contain truncated or oxidized forms that interfere with binding assays and cell-based experiments. This can lead to false positives or negatives when investigating elevation causes. Purity ≥98% minimizes these artifacts, providing reliable data.
Q: What storage conditions are recommended for bulk BNP peptide orders?
A: Lyophilized BNP should be stored at -20°C or below, protected from light and moisture. For reconstituted solutions, use sterile water or PBS and store at 4°C for up to 7 days. Avoid repeated freeze-thaw cycles. Proper storage preserves peptide integrity and supports accurate research on brain natriuretic peptide elevation causes.
