Chonluten analysis

The Chonluten Analysis is a targeted laboratory test designed to confirm the identity, determine the amount, and assess the peptide purity of Chonluten in lyophilised vials and raw active pharmaceutical ingredient (API) powders.

For lyophilised samples, results are reported in milligrams per vial together with peptide purity. Raw API powders can be evaluated using purity in % (m/m) together with peptide purity.

About Chonluten

Chonluten is a short synthetic tripeptide with the amino acid sequence Glu-Asp-Gly (EDG). It has been studied as a bioregulatory peptide associated primarily with the respiratory system.

Research on Chonluten has examined its effects on inflammatory and proliferative processes, including cytokine responses in cellular models.

Key Features

• Targeted identification and quantification of Chonluten
• Determination of peptide purity
• Suitable for lyophilised vials and raw API powders
• Analysis by HPLC
• Results for lyophilised samples reported in mg per vial and peptide purity
• Alternative result format for raw API powders includes purity in % (m/m) and peptide purity
• Minimum sample amount of one whole unopened vial with lyophilisate
• Minimum sample amount of 30 mg for raw API powders
• Average turnaround time of 7 business days

Analysis Parameters

• Target compound: Chonluten
• Molecular weight: 319
• Sequence: Glu-Asp-Gly-OH
• Testing method: HPLC
• Minimum amount of target compound for evaluation: Less than 1/20 of the usual dosage per vial
• Result format for lyophilised samples: mg per vial and peptide purity
• Result format for raw API powders: Purity in % (m/m) and peptide purity
• Minimum sample amount for lyophilised samples: One whole unopened vial with lyophilisate
• Minimum sample amount for raw API powders: 30 mg in a sealed glass vial to prevent the sample from absorbing moisture
• Average turnaround time: 7 business days

Important Notice

• This analysis is specifically intended for Chonluten. It does not automatically screen the sample for other peptides, related compounds, contaminants, or undeclared substances.
• For lyophilised samples, one whole unopened vial containing lyophilisate is required.
• Raw API powder should be supplied as at least 30 mg in a sealed glass vial to minimise moisture absorption.
• The alternative result format for raw API powders includes both purity in % (m/m) and peptide purity.
