Peptide Synthesis

CASLO has delivered peptides worldwide to research institutions, biotechnology and pharmaceutical companies for more than 19 years. CASLO peptides have been used in projects published in more than 800 international articles, and more than thousand not published projects.

CASLO guarantee the quality and specifications of peptides, and peptides are supplied with money back guarantee. Peptides are shipped together with a detailed product certificate containing all analytical data. 

Peptides can be made in almost all purities and quantities from 1 mg up to multiple grams. 

Peptides synthesis is offered in crude purity or as HPLC purified peptides with purities of: >70%, >75%, >85%, >90%, >95% or >98% and for some peptides >99%. Peptides can also be supplied bound to resin for further processing.

The correct sequence of an ordered peptide is verified and documented by mass spectrometry, and the purity by analytical HPLC. Peptides are delivered together with HPLC and mass spectrometry certificates.

If required CASLO can assist with finding the correct purity for the application the peptide will be used for. If you have other doubts about how to design your peptide, please contact us and we will do our best to help you.

Peptides are as standard made as lyophilized trifluoroacetate salts, but peptides can also be supplied as acetate or chloride salts. Peptides are packed under dry conditions with desiccant packs.

A large range of peptide modifications during or after peptide synthesis are possible, for example conjugation to carrier proteins, fluorochromes or biotin and many other modifications. Please click on "Peptide Modifications" on the menu bar for more information.

CASLO can predict an approximate solubility of a peptide sequence and give guidelines for how to dissolve a peptide before it is ordered. If the solubility is low, the peptide can eventually be ordered with a hydrophilic extension in order to increase the aqueous solubility. Solubility test can also be ordered when an order is placed for the peptide.
