Peptides are the complex protein derived compounds from organic molecular substances and hence they have typical structural configuration and the nature in which they respond to various processes involving their refining and purification. As the drugs formulated from research peptides constitute over wide array of range and engage high monitoring and error-free manufacturing in world’s leading scientific and biopharmaceutical research labs, the experts and the scientists authorize to manufacture these highly complex research compounds go for a extra mile ahead in terms of careful supervision and surveillance on the overall manufacturing and design process to achieve the best possible peptide drug’s nomenclature and chemical formation. The hi-tech designing of such many classified peptide have produced and made the availability of world acclaimed research drugs possible like GHRH, GHRP-2, GHRP-6, ALD403, IGF1-LR3 which are just a few research peptides among several available classifications, types and categories like GH Peptides, Melanotan 2, TB-500 and Cosmetic Peptides which were evolved time by time through consistent research and up gradation of manufacturing architecture. Purification process of Peptides involves a comprehensive method of crystallization to isolate and obtain the desired molecule and content but when it comes to achieve high efficacy, potency and high yields, various companies dealing in peptide purification business started concentrating on scopes of another yet advanced purification methods which utilize different principles of Chromatography such as Reverse phase chromatography (RPC), Ion Exchange Chromatography (IEC), Gel permeation chromatography (GPC). These advanced purification methods have replaced certain traditional peptide refining and fractioning methods which were under use in the past among which renowned ones are the Counter Current Distribution [1] and Partition Chromatography.
In process of purification, a sufficient care is taken so that the chances of generating impurities in peptide-based product mixtures should become negligible, it has been studied that the quality peptide solutions must not have impurities more than 0.1% otherwise the research and treating scopes of the prepared products will get compromised. The addition of major impurities which were observed during generation process are not limited to Diastereomers, hydrolysis products of labile amide bonds, deletion sequences formed predominantly in solid-phase peptide synthesis, Polymeric forms of the desired peptide and by-products formed during removal of protection groups. The challenge faced when we are to develop a process employing chromatography as the purification principle is to isolate the desired peptide in the mother liquor from a complex mixture of impurities discussed above. Now we shall discuss the potential and efficient purification methods based on chromatographic media principles as mentioned above, which help deliver the high yielding and best quality peptide based research compounds.
1. REVERSE PHASE CHROMATOGRAPHY (RPC) This advanced method is the most powerful and known procedure in the peptide purification, it implants hydrophobic interactions as the main split principle. It uses stationery phase and an aqueous mobile phase containing organic solvent alcohol. For the large scale and industrial purifications it uses reversed phase resins, which are very popular types of methods based on C-4, C-8 and C-18 alkyl chains attached to a silica surface.
2. ION EXCHANGE CHROMATOGRAPHY (IEC) In this method, Separation depends on the ionic interaction between the support surface and charged groups of the peptide. Both cation (a positively charged ion) and anion ( a negatively charged ion) exchangers have been used with success for peptide purifications. For large-scale purification, high flow-rates and efficiency are compatible. Such high performance ion exchangers of different chemical compositions are now commercially available.
3. GEL PERMEATION CHROMATOGRAPHY (GPC) This method separates molecules primarily on the basis of size exclusion. The technique is highly efficient for separation of polymeric forms of peptides and for desalting of peptide solutions. Sephadex is a well-known example of a commercially available gel permeation material and has been used successfully in purification of various molecules .
