Quality Control (QC)
Quality Control (QC) — The systematic processes and procedures ensuring that a manufactured peptide meets defined specifications for identity, purity, and potency.
What Is Quality Control?
Quality control (QC) is the set of analytical tests performed on a peptide product to verify it meets predetermined specifications before release for use. QC testing confirms the peptide's identity, purity, potency, and safety at both the raw material and finished product stages. For GMP-grade peptides, QC follows ICH guidelines with validated methods and documented specifications.
Standard QC Panel for Research Peptides
- Identity: MS molecular weight (±0.1% of theoretical)
- Purity: RP-HPLC ≥ 95% for research grade, ≥ 98% for in vivo grade
- Content: Net peptide content by AAA or UV
- Appearance: White to off-white lyophilized powder
- Solubility: Clear solution at specified concentration
- Safety: Endotoxin < 1 EU/mg for cell culture grade
