Our team has rich experience in project development, custom synthesis of peptide products, synthesis process development and drug peptide modification, supporting the research and development of peptide apis, the company can carry out reasonable transformation strategy design for the target peptide according to your requirements. We offer a variety of options in size, purity level, modification and salt form. Our goal is to quickly provide high quality peptide products for your drug discovery research! With a wide range of synthetic scales from mg to kg and fast turnaround times, the product can be delivered in resin, coarse powder and purified powder form with the required purity up to 99%. A wide range of peptide products, including linear peptides, cyclic peptides, modified peptides and peptide-based complex couplings.
Difficult peptide | Conventional peptide | Fast peptide | Rush peptide | |
| Delivery period | 20 days or more | 10 days | 6 days | 3 days |
| The sequence length | Up to 500AA | 5-25AA | 5-25AA | 5-25AA |
| Purity | Pure crude product -99% | Crude product -99% | Crude product -99% | Crude product |
| Specifications | mg | mg-kg | mg | mg-g |
| Type | Retouching based on customer needs | More than 300 extensive retouching | More than 30 retouching | More than 30 retouching |
| Solubility test | √ | √ | √ | × |
| Salt containing species | TFA、HCL、ACE、Free | TFA、HCL、ACE、Free | TFA | TFA |
Note: Common are TFA salt, HCL salt, ACE salt and desalting (free form), TFA salt is the standard form, customers can choose other forms of salt service according to the experimental requirements.
The common purity is 90% 95% 98% (due to the peptide itself, it is not guaranteed that each peptide can reach more than 98% purity.
Common difficult peptides include long-chain peptides, cyclic peptides, multi-pair disulfide polypeptides, and other difficult modified polypeptides. Difficult peptides have the risk of failure due to the difficulty of synthesis. We will try our best to complete the commissioned production.
Carrier proteins can be coupled, such as KLH, OVA, BSA, etc.
When a large number of peptides are produced, they can be delivered in batches, and we guarantee the stability of products between batches.
Each of our peptides has undergone multiple MS and HPLC tests in the production process (detection equipment is, the chromatographic column is C18 column) to ensure that the quality of the peptide products meet customer requirements. And for each peptide to provide COA documents, including the peptide sample quality spectrum, shape and appearance, delivery specifications, molecular quality and purity information (if there are other quality requirements, please inform us in advance) Kang Yong Rui to provide peptide packaging services (the first 10 tubes free, each tube minimum of 100μg) polypeptides are generally delivered in the form of freeze-dried powder, Packaged in individual sample tubes according to customer requirements.
The customer can raise objections within 10 working days after receiving the product, and return or exchange the product free of charge after determining that the product is unqualified; Provide after-sales service within 1 year.
