Chonluten powder is a synthetic tripeptide made from the short sequence Glu-Asp-Gly, also written as EDG. It is a small peptide chain with a molecular weight of 319.27, so the structure is much simpler than long peptide fragments or protein-based materials. In production, the peptide is usually prepared by solid-phase peptide synthesis, purified by HPLC, and then freeze-dried into a white or off-white powder for easier storage and handling.
This EDG tripeptide is mainly used in laboratory research related to short peptide regulation, respiratory-related cell models, peptide signaling studies, and molecular biology assays. Since the sequence is short and clearly defined, buyers usually pay attention to purity, water solubility, molecular weight confirmation, moisture level, and batch documents. The material is supplied for research use only.
Shaanxi Medibridge Biotech Co., Ltd. provides research-grade peptide raw materials in bulk powder and vial forms. We support custom vial filling, private labeling, COA, HPLC, LC-MS, MSDS, and batch traceability.

EDG Sequence Notes
The EDG sequence refers to three amino acids: Glu, Asp, and Gly. Both Glu and Asp have acidic side chains, while Gly is the smallest amino acid in common peptide structures. This gives the molecule a very short and clean chain, with a molecular weight of only 319.27.
For this kind of small tripeptide, the sequence itself is one of the main specification points. The powder is usually checked by HPLC for purity and by MS for molecular weight confirmation. Appearance, water solubility, moisture level, and batch COA are also part of the normal quality file for supply. The structure is simple, but the batch information still needs to be clear enough for laboratory research use.

Why This Tripeptide Is Different
Chonluten is built from only three amino acids: Glu, Asp, and Gly. The chain is short, but it has a clear acidic character because both Glu and Asp carry acidic side groups. Gly sits at the end of the sequence as the smallest amino acid, keeping the whole molecule compact and light.
With a molecular weight of 319.27, this EDG tripeptide is much smaller than many common research peptides. Its structure is not complicated, and that is part of its identity. The material is defined by a simple sequence, a small molecular size, water solubility, and a clean lyophilized powder form. In short peptide research, these basic details matter more than broad functional language.

Research Use Context
This EDG tripeptide is mainly used in laboratory research where short peptide behavior needs to be observed in a controlled setting. It may appear in studies related to peptide signaling, cell response models, respiratory-related cell research, and basic molecular biology assays.
Because the sequence is very short, it is also used in comparative peptide work, especially when researchers need a simple tripeptide structure rather than a long peptide chain. In this kind of research setting, the material is usually valued for its defined sequence, small molecular weight, water solubility, and stable lyophilized powder form.
The product is supplied for laboratory research use only. It is not supplied for human use, clinical use, or therapeutic application.

Powder Form & Lab Handling
Chonluten powder is usually supplied as a white or off-white lyophilized powder. The freeze-dried form helps keep the material dry and easier to store before preparation. Since the peptide has a short EDG sequence and good water solubility, it can be prepared in water or common research-use buffer systems depending on the lab setting.
The powder should be kept sealed, dry, and protected from strong light. Low-temperature storage is commonly used for peptide raw materials, especially when the product is kept for longer periods. After opening, the material should be handled in a dry environment to reduce moisture exposure.
For vial filling or custom packaging, the powder can be supplied in different mg-per-vial formats. Each batch can be matched with COA and related test documents for research-use supply.

Batch Quality & Documents
For a short peptide like EDG, the batch file is usually kept simple but complete. Purity is checked by HPLC, and molecular weight can be confirmed by MS. Appearance, solubility, moisture level, and related impurity information are also part of the normal quality record.
Each batch can be supplied with COA and supporting test documents. The COA usually lists appearance, identification, purity, water content, MS result, storage condition, and conclusion. For vial filling orders, the batch number, filling amount, label information, and packaging details can also be matched with the same production record.
This kind of document support is useful for research-use raw material supply, especially when the same specification needs to be ordered again later. The focus is on clear batch information, traceable testing, and stable specification control.
