Area of Science:

• Biochemistry
• Synthetic Chemistry
• Molecular Biology

Background:

• Peptide libraries are crucial tools in drug discovery and biological research.
• Current methods for preparing binary peptide libraries face limitations in efficiency and control.

Purpose of the Study:

• To introduce and validate a new portioning-mixing method for binary peptide library preparation.
• To demonstrate the method's capability in accurately assembling library components.
• To explore the scalability and screening potential of the generated libraries.

Main Methods:

• Development of a novel "non-coupling" operation within a portioning-mixing framework.
• Preparation of a simple binary peptide library using the new method.
• Analytical assessment of the mixture to confirm the presence and ratios of all components.

Main Results:

• The portioning-mixing method, with the non-coupling operation, is effective for binary peptide library synthesis.
• Experimental results confirm the presence of all intended peptide components in the prepared library.
• The study discusses the influence of component number and molar ratios on library characteristics.

Conclusions:

• The novel portioning-mixing approach offers a robust and reliable strategy for binary peptide library construction.
• This method enhances the precision and versatility of peptide library preparation for screening applications.
• Further investigations into optimizing component ratios and screening protocols are warranted.
