Comparison Guide,starting at .20 per amino acid

When embarking on research or development that requires custom peptides, understanding the associated costs is paramount. GenScript peptide synthesis price is a frequent query among scientists and researchers, and for good reason. The quality, purity, and turnaround time of synthesized peptides directly impact experimental outcomes, making informed decisions about pricing crucial. This article delves into the factors influencing GenScript peptide synthesis price, exploring various service offerings, pricing structures, and considerations that contribute to the overall cost.

GenScript peptide synthesis is a cornerstone for many in the life sciences, providing a wide array of services from standard to highly complex custom peptides. The company is known for its commitment to quality, with custom synthesized peptides from GenScript manufactured under strict high-level quality control processes, backed by their ISO 9001 certification and Total Quality Management system. This dedication to quality assurance is a significant factor in their pricing.

Factors Influencing GenScript Peptide Synthesis Price

Several key elements contribute to the GenScript peptide synthesis price:

* Peptide Length and Complexity: The number of amino acids in a peptide sequence is a primary cost driver. Longer peptides generally require more reagents, time, and purification steps, thus increasing the peptide price. Similarly, peptides with complex modifications, unusual amino acids, or challenging sequences can incur higher costs due to the specialized techniques and expertise required for their synthesis. GenScript can synthesize peptides with up to 3 disulfide bonds, but the complexity of such syntheses is reflected in the pricing.

* Purity Requirements: Different research applications demand varying levels of peptide purity. GenScript peptide synthesis offers a range of purity levels, from crude peptides to highly purified (>98%) options. The higher the required purity, the more intensive the purification process, leading to a higher GenScript peptide synthesis price. For instance, crude peptide synthesis might start from $3.35/aa, while high purity peptide synthesis (>98%) can range from $17.47/aa.

* Scale and Quantity: The quantity of peptide needed significantly impacts the cost. While initial research might only require milligram quantities, larger-scale production for preclinical or clinical studies will have different pricing structures. GenScript offers a large-scale peptide synthesis service designed for such needs, with pricing that scales accordingly. Some price lists indicate prices for quantities like 1-4 mg, $14.14, $9.90, $15.47, $10.83, and larger quantities like 60mg, $6.5, $7.5 per amino acid in their Standard Peptide Synthesis Price List.

* Turnaround Time: GenScript offers various turnaround times, including expedited services. Faster delivery often comes at a premium. For example, their TurboTIDE Peptide Synthesis Service guarantees speed, often offering production in 5/7 business days – or your money back. This rapid service is designed for urgent research needs and is typically priced higher than standard delivery options.

* Modifications and Special Features: Peptides can be synthesized with a wide range of modifications, such as N-terminal or C-terminal modifications, phosphorylation, glycosylation, and fluorescent labeling. These add-ons require specialized chemistry and can significantly increase the GenScript peptide synthesis price. The synthesis of peptides with an unlimited range of modifications is available, with pricing potentially starting at €1.66 per amino acid.

* Specific Services and Platforms: GenScript utilizes various proprietary platforms to enhance peptide synthesis. For example, their PepPower™ Peptide Synthesis Platform is designed to enhance synthesis success rates and accelerate discoveries. The use of such advanced technologies can influence the overall cost.

Understanding Pricing Structures and Examples

GenScript provides various ways to understand their pricing:

* Per Amino Acid Pricing: A common method is pricing per amino acid. This is particularly useful for estimating the cost of custom sequences. For example, their standard custom peptide synthesis can start at $3.20 per amino acid. Other providers may offer competitive prices, starting at $3.50/residue to $4.50/residue for crude peptides.

* Fixed Pricing for Standard Peptides: GenScript also offers a catalog of pre-synthesized peptides, often referred to as catalog peptides. These have fixed prices, making them a cost-effective option for commonly used sequences. Examples include \u03b2-Amyloid (1-40) for $114.00 or \u03b1-Factor Mating Pheromone, yeast for $120.00. Other catalog items like CEF pool (extended)-70% are priced at $160.00.

* Project-Based Quotes: For highly complex or large-scale projects, GenScript provides custom quotes based on the specific requirements of the peptide synthesis. This ensures that clients receive pricing tailored to their unique needs. One user reported being quoted 1500 euros for a 11 amino acid custom peptide, highlighting that complex requests can lead to higher figures.
