Peptide Synthesis

RPeptide provide custom peptide synthesis services.

Customers provide information on the sequence, structure (such as the introduction of other groups or structures), purity, quantity, and salt system of the peptide. We provide the corresponding peptide products according to these requirements.

 

1, The polypeptide sequence description: the basic structure of the polypeptide is composed of one amino acid, the customer can provide the corresponding amino acid sequence, there are two letters and three letters. The left side is the N end and the right side is the C end.

 For example, the single letter of the polypeptide H6 is: HHHHHH. The three letters are His-His-His-His-His-His or H-His-His-His-His-His-His-OH.

 

 

2, The structure of the polypeptide: in the complete structure of the polypeptide, usually in addition to the basic sequence, there are some other compounds, such as fluorescently labeled compounds, fatty acids, PEG, etc., customers need to introduce such structures in the polypeptide sequence, Before placing an order, please explain with our sales staff, or provide a complete map of the chemical structure of the peptide (we sales staff can help draw the structure), in order to determine the uniqueness of the structure of the polypeptide. 

 

3, The purity of the peptide: polypeptide organisms can provide crude peptides and purity of >70%, >75%, >80%, >85%, >90%, >95%, >98%, >99% pure Peptide. Most of them choose the purest peptide with the highest cost performance of “>95%” purity. 

 

4, Description of the number of peptides: The peptide-specific organisms provide milligrams and grams of peptides for the needs of scientific research, such as ordering 5mg or 10g. For additional dispensing, peptide-specific organisms can also be dispensed according to your requirements. For example, 100mg is divided into 30mg+30mg+40mg, a total of 3 tubes. 

 

5, Description of the peptide salt system: Since the conventional mobile phase used for peptide purification is 0.1% TFA/H2O and 0.1% TFA/ACN, the basic group of the final polypeptide will carry trifluoroacetic acid, forming a stable state, which we call It is a trifluoroacetic acid system. Some customers' experiments are not exposed to trifluoroacetic acid, such as cell experiments. For this purpose, the peptide-specific organisms provide the acetic acid system, the hydrochloric acid system, and the polypeptide of the phosphoric acid system, which are available for customers to choose, and the price is usually 1.3-1.4 times that of the conventional trifluoroacetic acid system polypeptide. 

 

6, Description of peptide delivery standards:

 

1. The product itself provides the corresponding peptide products according to the conditions required by customers. Refer to Articles 1 to 5.

 

2. Test report We will provide the HPLC map of the peptide, MS map and COA report.

 

 


 

RPeptide provide custom peptide synthesis services, and the price of the polypeptide is mainly divided into two parts, the price of the common sequence part and the price of the modified part.


1, The price list of the common sequence. (20% off the price in 2019)

 

                                                                     

The amino acid price list is applicable to the calculation of the price of a simple or medium synthetic difficulty coefficient, the number of amino acids is less than or equal to 30, and the number is less than or equal to 1 gram.

 

The price of the ordinary sequence is an example. (If you don't understand, you can contact our sales staff)

  1. Order the polypeptide H2N-Ala-Pro-Ser-Gly-Ala-Gln-Arg-Leu-Tyr-Gly-Phe-Gly-Leu-NH2, 13AA, 20 mg, 95%, trifluoroacetic acid contect.

      Price = 13 * $21.0 * 0.8 (8 fold) = $218. 

        218 dollar is of the price of the peptide (13AA, 20 mg, 95%)

 

  2. Order the polypeptide H2N-Tyr-Arg-Gln-Ser-Met-Asn-Asn-Phe-Gln-Gly-Leu-Arg-OH, 12AA, 200 mg, 90% or more, trifluoroacetic acid contect.

      Price = 12 * $27.7 * 1.4 * 0.8 (8 fold) = $372. 

        372 dollar is of the price of the peptide (12AA, 200 mg, 90%)

 

  3. Order the polypeptide Ac-Ser-Tyr-Ser-Met-Glu-His-Phe-Arg-Trp-Gly-Lys-Pro-Val-Gly-OH, 14AA, 100 mg, 95% or more, acetic acid system.

        Price = 14 * $34.3 * 0.8 (8 fold) * 1.3 (times) = $499. 

        499 dollar is of the price of the peptide (14AA, 100 mg, 95%, Acetic acid contect)

       We replace trifluoroacetic acid with acetic acid, so the price needs to be multiplied by 1.3.

 

2, The modify the price. 

Since the modification price is affected by factors such as the polypeptide sequence, the type of modification and the price of the raw material, if your peptide needs to be contacted by a salesperson, an inquiry is made.
