Peptide purification

PEPTIDE PURIFICATION

Proteogenix proposes a large range of purity levels:

• Crude / Desalted peptide

• Immunograde peptide (purity >75%): the crude peptide is either 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.
