Rapid Induction Heating
The Prelude® X is the first instrument of its kind to include rapid induction heating. The patent-pending technology takes just seconds to reach temperature, and enables controlled heating between 25 degrees C and 90 degrees C. Each of the 6 reaction vessels is equipped, and the heating parameters can be independently programmed and controlled. The technology is fully-compatible with oscillation mixing, which ensures even temperature profiles, homogenous chemistry, and high yields.
All 6 reaction vessels on the Prelude X are equipped with oscillation mixing. This method creates a uniform heating profile throughout the reaction vessel, eliminating the potential for hot spots or burnt resins. Additionally, it functions to keep resins off the side walls and submerged within the solution. Combined with the fully adjustable nitrogen mixing that is also included on each reaction vessel, the Prelude X allows complete control of reaction parameters for precise and reproducible peptide synthesis.
Minimize trial-and-error when synthesizing difficult peptides using real-time UV monitoring on the Prelude X. The Prelude X monitors the reaction solution while it’s mixing – enabling full control of the deprotection reaction times, not just the number of repetitions.
Efficient Reagent Additions
The Prelude X comes with up to 27 amino acid positions to accommodate any chemistry. Expensive reagents can be added to any reactor without priming or wasting a drop using Single-Shot™ deliveries, thus saving money with no manual intervention required and allowing greater automation capacity.
The Prelude X features automated, fully customizable cleavage options. Choose to cleave immediately (Fmoc only), at the end of a synthesis, or at a specified date and time. Cleaved peptides are collected in convenient 50 mL centrifuge vials. All PTI synthesizers are built with robust TFA-resistant materials, so you can cleave for years on the instruments without worry.
The Prelude X has the ability to run 3 preactivation reactions in parallel. This is ideal for sterically hindered amino acid additions. Additionally DIC/HOBt chemistry can be optimized and go straight to scale-up.
Efficiently rinses your reaction between steps.
Reliability – the PTI difference
Other systems use off-the-shelf valves that leak, cross-contaminate, and quickly fail when exposed to harsh peptide synthesis chemicals. Our patented valve block system was specifically designed for peptide synthesis, so you get zero dead volumes, no cross-contamination, and worry-free performance that lasts for years.
Personalized User Databases
Individual users can create their own programs, peptide sequences, and syntheses that can only be accessed from their own personalized user database. Individual databases can be stored on the instrument, or on a portable USB drive.
E-mail Notification Feature
Have the Prelude X send an email to a computer or cell phone at a specified program step, at the beginning of each cycle, or when an error occurs.
Safe Response Feature
The Prelude X can rinse and drain a reaction with a solvent of choice if a synthesis is interrupted for any reason.
Dynamic Sequence Programming
Need more flexibility? The Dynamic Sequence Programming option allows the reaction vessels to operate semi-independently. Have one peptide run a special cycle in the middle of a sequence while the other reaction vessels sit idle. Add pre- or post-processing cycles. Or add or remove amino acids from a peptide sequence.
