Cardigan Powder is a synthetic tetrapeptide material with the sequence Ala-Glu-Asp-Arg, often shortened as AEDR. In the peptide market, it is also commonly connected with the name Cardiogen. This material is not extracted from plants or animal tissue. It is made by peptide synthesis, then purified by HPLC and dried into a stable powder form for easier laboratory storage, testing, and small-batch handling.
The AEDR sequence is short, but it has a clear structure profile. Glu and Asp bring acidic groups, while Arg adds a basic side chain at the end of the peptide. Because of this mixed amino acid pattern, this tetrapeptide is often used in research work related to short regulatory peptides, peptide signaling, cardiovascular biology models, fibroblast studies, and cell-level comparison experiments. It is supplied as a research-grade raw material only, not as a finished health or medical product.
Shaanxi Medibridge Biotech Co., Ltd. supplies synthetic peptide powders with controlled purity, clear batch documents, and flexible vial filling service. For buyers who need AEDR peptide powder, Cardiogen peptide supplier support, or custom peptide vial filling from China, we can provide raw powder, labeled vials, COA, HPLC data, LC-MS support, and repeat-order batch consistency.

What Makes the AEDR Sequence Different
|
The AEDR sequence looks simple at first glance, but it is not a plain neutral peptide chain. It contains alanine at the beginning, two acidic amino acids in the middle, and arginine at the end. This gives the peptide a mixed charge profile, which is one reason buyers often check both sequence identity and purity data before placing an order.
Glu and Asp are both acidic residues. They make the molecule more polar and easier to work with in water-based lab systems. Arg is different. It has a basic side chain and adds another layer of charge behavior to the sequence. For researchers comparing short regulatory peptides, this small change can matter. Because the chain is only four amino acids long, the material is usually not judged by appearance alone. More practical points include HPLC purity, LC-MS confirmation, water solubility, moisture control, and whether the same specification can be supplied again for repeat studies. |
Research Context
This material is usually discussed in the context of short regulatory peptide research. The main interest is not its appearance, but its defined AEDR sequence, small molecular size, and how it may be used in controlled cell-level studies.
In laboratory work, this tetrapeptide may be used in cardiovascular biology models, fibroblast-related studies, peptide signaling research, and sequence comparison experiments. Some researchers also pay attention to its possible link with cytoskeletal and nuclear matrix protein expression in cell models. These are research directions, not finished product claims.
For this type of AEDR tetrapeptide, the supporting documents usually include HPLC purity, LC-MS confirmation, solubility information, and batch records. The powder form, moisture level, and repeatable specification are also part of the supply details. It is provided as a research-use synthetic peptide, available in raw powder or vial form.
Cell Model Research Notes
In published research, the AEDR tetrapeptide has been discussed in connection with cell-level regulatory studies. The focus is usually placed on how a short, defined peptide sequence may relate to cellular protein expression, rather than on broad finished-product claims.
For this material, fibroblast-related models are one common research angle. Some studies also look at cytoskeletal and nuclear matrix proteins, such as actin, tubulin, vimentin, and lamin A/C. These markers are often used when researchers want to observe cell structure, protein expression, and peptide-related response patterns under controlled conditions.
In cell model work, a short AEDR sequence is easier to define and compare than larger peptide fragments. Its small molecular weight, clear sequence, and controlled purity make it suitable for studies where researchers need a simple peptide material with stable batch information. Raw powder and vial formats can also be prepared for different laboratory testing plans.
Powder Form & Handling
Cardigan Powder is normally supplied as a white to off-white lyophilized powder. This form is convenient for small research batches, vial filling, and long-distance shipment. Compared with solution form, dry powder is easier to store and gives buyers more flexibility when preparing their own lab solutions.
This AEDR peptide is soluble in water and common laboratory buffer systems. In actual preparation, the final concentration and solvent system usually depend on the test design. Since it is a short synthetic peptide, the powder should be kept sealed, dry, and protected from repeated moisture exposure.
For storage, low-temperature conditions are usually preferred. Unopened material can be packed in sealed vials or raw powder packaging according to order size. After opening, the material should be handled in a clean, dry environment. Batch COA, purity data, and basic handling notes can be provided with the shipment.
Custom Supply & Documentation
This AEDR peptide can be supplied as raw powder or filled into vials according to the order plan. For small research batches, vial format is often easier to handle. For larger preparation work, raw powder packaging can be arranged based on the required quantity.
Custom details can be discussed before shipment, including vial size, mg per vial, label style, packing method, and document requirements. For repeat orders, the same specification can be followed as closely as possible, including purity level, appearance range, filling format, and batch document style.
Each batch can be supported with basic quality documents, such as COA, HPLC purity data, LC-MS confirmation, and handling notes. Private label peptide supply, custom peptide vial filling, and small-batch peptide powder orders are available for laboratory research use.
