Catalog peptides, also known as off – the – shelf peptides, are pre – synthesized peptides that are readily available in a supplier’s catalog. These peptides serve a wide range of applications, from basic research in biochemistry and pharmacology to more advanced applications in drug discovery and diagnostics. As a catalog peptides supplier, I often receive inquiries about the price range of these products. In this blog, I will delve into the factors that influence the price of catalog peptides and provide an overview of the typical price range. Catalog Peptides
Factors Influencing the Price of Catalog Peptides
1. Peptide Length
One of the most significant factors affecting the price of a catalog peptide is its length. Peptides are chains of amino acids, and the synthesis process becomes more complex and time – consuming as the number of amino acids increases. Each additional amino acid in the peptide sequence requires a specific chemical reaction to be added to the chain accurately. For short peptides, typically those with 5 – 10 amino acids, the synthesis is relatively straightforward. The cost of materials and labor is lower, resulting in a relatively affordable price. On the other hand, longer peptides, say 50 or more amino acids, require a highly precise and multi – step synthesis process. This complexity drives up the production cost, and thus, the price of the peptide.
2. Amino Acid Composition
The type of amino acids used in the peptide sequence also plays a crucial role in determining its price. Some amino acids are more expensive than others due to their complex chemical structures or the difficulty in sourcing them. For example, non – natural amino acids, which are often used in specialized research to introduce unique properties to the peptide, are generally much costlier than the standard 20 amino acids. Additionally, amino acids with special modifications, such as phosphorylation, acetylation, or glycosylation, require additional chemical reactions during synthesis. These modifications not only increase the cost of the raw materials but also add to the complexity of the manufacturing process, leading to higher prices for the final peptide product.
3. Purity Requirements
Purity is another critical factor in peptide pricing. Peptides can be synthesized with different levels of purity, usually expressed as a percentage. For general research purposes, peptides with a purity of 70% – 80% may be sufficient, and these are relatively inexpensive. However, in applications such as in – vivo studies or clinical trials, higher purity levels of 95% or above are often required. Achieving such high purity levels involves additional purification steps, such as high – performance liquid chromatography (HPLC). These purification processes are time – consuming and require expensive equipment and reagents, which significantly increase the cost of the peptide.
4. Quantity Ordered
The quantity of peptides ordered also has a direct impact on the price. As with many products, there are economies of scale in peptide synthesis. Ordering larger quantities of a particular peptide often results in a lower per – unit cost. This is because the fixed costs associated with setting up the synthesis process, such as equipment calibration and reagent preparation, can be spread over a larger number of peptide units. For small – scale research projects, ordering a small quantity of peptides may be more expensive on a per – milligram basis compared to large – scale industrial orders.
5. Customization and Special Requirements
If a customer requests a custom – synthesized peptide, the price will be higher than that of standard catalog peptides. Customization may involve incorporating specific amino acid sequences, modifications, or conformations. These special requirements often demand additional research and development efforts, as well as modifications to the standard synthesis protocols. Moreover, if the customer requires special packaging, such as lyophilization in a specific vial or under a particular atmosphere, or rapid delivery, these services will also add to the overall cost of the peptide.
Typical Price Range of Catalog Peptides
Based on the factors mentioned above, the price range of catalog peptides can vary significantly.
Short and Simple Peptides
For short peptides with 5 – 10 amino acids and relatively simple amino acid compositions, and a purity level of around 70% – 80%, the price can range from $100 – $300 per milligram. These peptides are commonly used in preliminary research experiments, such as screening assays or basic biochemical studies. For example, a simple pentapeptide with natural amino acids and no special modifications can be relatively inexpensive, making it accessible for researchers with limited budgets.
Medium – Length and Standard Purity Peptides
Peptides with 11 – 20 amino acids and a purity of 80% – 90% typically cost between $300 – $800 per milligram. These peptides are often used in more in – depth research, such as studying protein – protein interactions or developing peptide – based probes. The increased length and purity requirements contribute to the higher price compared to shorter peptides.
Long and High – Purity Peptides
Long peptides with 21 or more amino acids and a purity of 95% or higher can cost upwards of $800 per milligram, and in some cases, even several thousand dollars per milligram. These high – end peptides are used in advanced applications, such as drug development, where the quality and purity of the peptide are crucial for the success of the project. For example, a long peptide with multiple non – natural amino acids and high – level modifications for a specific drug candidate can be extremely expensive due to the complexity of its synthesis and purification.
