Core Molecular Specs & Technical Index

Understanding the fundamental molecular properties of anti inflammatory peptides is essential for evaluating raw material quality. These peptides typically range from 5 to 30 amino acids in length and exhibit specific physicochemical characteristics that influence their performance in formulations and assays.

Basic Properties

Anti inflammatory peptides are characterized by their molecular weight, isoelectric point, and hydrophobicity index. Standard molecular weights fall between 500 and 3500 Da, with an isoelectric point typically between 5.5 and 8.0. The hydrophobicity index, measured via reverse-phase HPLC retention time, directly correlates with membrane permeability and stability in aqueous solutions.

Purity Specifications

High-grade anti inflammatory peptides require a minimum purity of 98% as determined by HPLC analysis. Premium grades achieve 99% or higher, with individual impurity peaks not exceeding 0.5%. Counter-ion content, typically trifluoroacetate (TFA) or acetate, must be controlled below 5% to avoid interference in biological assays.

Solubility & Stability

These peptides demonstrate optimal solubility in water, phosphate-buffered saline (PBS), or dimethyl sulfoxide (DMSO) at concentrations ranging from 1 to 10 mg/mL. Lyophilized powder stored at -20°C under desiccated conditions maintains stability for 24 months. Reconstituted solutions should be used within 72 hours when stored at 2-8°C.

Technical Specifications List

• Purity (HPLC): ≥98% (standard), ≥99% (premium grade)
• Molecular Weight: 500–3500 Da, confirmed by mass spectrometry
