About Qingli Shangmao—Your Premier Research Peptide Suppliers Partner

Qingli Shangmao (www.qinglishangmao.com) is a China‑based peptide factory specializing in custom and catalog peptides for research. Over the past seven years, we have grown from a small lab to a global supplier, serving academic institutions, CROs, and biotech companies. Our core strengths include:

• Seven years of expertise in solid‑phase peptide synthesis

• Strict QC protocols, including HPLC and mass spectrometry for ≥ 98% purity

• Fast shipping: domestic orders within 2 days, international in 3–5 days

• Dedicated B2B support: English‑speaking account managers and technical scientists

As one of the most reliable research peptide suppliers, Qingli Shangmao has built a reputation for consistency, transparency, and responsiveness.

Why Purity Matters with Research Peptide Suppliers

High peptide purity directly impacts experimental reproducibility. Impurities can:

1. Skew assay results, leading to false positives or negatives

2. Complicate downstream analyses, such as binding studies

3. Reduce peptide stability, shortening shelf life

Therefore, reputable research peptide suppliers like Qingli Shangmao guarantee ≥ 98% purity. We provide a detailed Certificate of Analysis (CoA) with every order, including:

• HPLC chromatograms

• Mass spectrometry spectra

• Peptide sequence and molecular weight

By placing your trust in www.qinglishangmao.com, you minimize the risk of experimental failures.

Quality Certifications & Documentation

To ensure global compliance, Qingli Shangmao maintains:

• ISO 9001:2015 quality management system

• GMP‑grade production lines (upon request)

• Third‑party audits by TÜV SÜD

These certifications reinforce our position among leading research peptide suppliers.

Custom Peptide Synthesis—Advanced Services

Beyond catalog peptides, Qingli Shangmao excels at custom sequences. Our custom services include:

• Post‑translational modifications, such as phosphorylation and glycosylation

• Labeling with fluorophores or biotin

• Peptide stapling for enhanced stability

• Isotope‑labeled peptides for quantitative proteomics

Because we integrate customer feedback into every project, we rank highly among research peptide suppliers for technical flexibility.
