PEPscreen Webinar

Watch the webinar and learn about the importance of utilizing custom peptide libraries for different types of screening applications. You will learn about designing the optimal peptide libraries as well as epitope mapping and ELISPOT assays involving peptide libraries. You will also learn from other researchers how they are utilizing peptide libraries in their specific applications.

Design

Design your library with ease using our convenient design tool. It enables you to design overlapping peptide fragment libraries, alanine scanning libraries, truncation libraries, and positional scanning libraries.

You’ll be able to:

• Set custom sequence parameters (peptide length and amino acid offset)
• Format the sequence output
• Export the custom peptide library sequences (MS Word, Excel, etc.)

Benefits

We have developed a proprietary custom peptide synthesis platform utilizing Fmoc chemistry, providing a solution to enhance peptide screening applications. Using this technology we can provide high-quality peptide libraries with:

• Low variability: Completely automated synthesis eliminates errors
• Fast delivery: Receive your library in less than 7 business days!
• Unsurpassed flexibility: Include multiple peptide lengths and designs in a single library
• Easy-to-use formatting: Individual tubes are in 96-well format making it compatible with high-throughput robotic assays and eliminates cross-contamination. Individual tubes are triple-labeled for maximum user flexibility
