+ What purity would you advise me to use for my peptide synthesis project?
ProteoGenix proposes a large range of purity levels for your peptides:
- Crude peptide / Desalted peptide
- Immunograde peptide (purity >75%): the crude peptide is precipitated and washed several times for the complete extraction of organic impurities and to remove most secondary products. This level of purity of the peptides is usually enough for generating or testing antibodies.
- Purified peptides (purity >85%): further purification by preparative HPLC allows the elimination of peptides resulting from incomplete coupling (i.e. peptide lacking one or more amino acids). The 85% purified peptides can be used for antiserum production, ELISA antibody titration and monoclonal antibody production for example.
- Highly purified peptide (purity >95%): this level of purity is required for most biological or enzyme activity studies.
- Purity > 98% or > 99% can also be performed.

Lowercase letters are considered by our system as D-Amino Acids, if you do not require this type of Amino Acids, please replace yellow highlighted letters by capital letters.

Sequence Sent.

Your sequence contents more than 8 consecutive identical characters or Lys or Arg which may lead to synthesis difficulties and the sequence should be checked by our chemist to provide a quotation.

Letter highlighted in red do not correspond to any Amino Acid recognized by our system. It’s either a typo or a possible specific modification. Please correct the typo or remove the modification and select it next step to proceed.
