Flash Cartridges Address a Peptide Synthesis Bottleneck
The SNAP Bio C18 and C4 cartridges are a new series of high-performance flash cartridges with wide pore media (300 å) for reversed-phase purification of peptides and other large molecules. Reversed-phase high-performance liquid chromatography (RP-HPLC) is one of the main bottlenecks in the peptide synthesis workflow, limited by small loading amounts, long separation times, poor recoveries, and high costs. These cartridges offer similar performance to traditional formats, but in a flash design and at a fraction of the cost. They have a higher loading capacity than prep RP-HPLC, enabling more peptide to be processed in a single injection, as well as faster, more efficient peptide purification. Flash formats also require less solvent, thereby creating less waste. The columns are available in 10-g, 25-g, 50-g, and 100-g sizes.
Bioprocess Controller Determines Key Process Information
The high metabolic burden during recombinant protein production in E. coli can cause cell death and lysis, increasing impurities and product loss. PATfix is an in-process control system that offers fast and precise analysis and monitoring of bioprocesses. It retrieves key process information, such as the optimal time of harvest, to help facilitate important process decision-making. High-performance liquid chromatography (HPLC) fingerprinting supported by chemometric techniques evaluates data and indicates an optimal harvest time. Integrated multivariate data analysis (MVDA) tools determine deviations from optimal conditions. Impurity monitoring enables reliable detection of physiological events in the bioreactor, eliminating the need for cumbersome offline analytics.
Filtration System Prepares Samples for Clarification
Preparing samples by clarification is an essential step prior to nearly all analytical techniques, such as highpressure liquid chromatography (HPLC). This filtration step to remove particles is crucial for maintaining the integrity of chromatography columns and for maximizing their operating life. The Claristep is a fast, small-volume filtration system that consists of a workstation and filter units. It does not require the addition of any leachables or extractables to the original sample. An exchangeable tray enables easy and accurate positioning of sample vials and filter units. Unique grooves in the filter unit’s lid automatically guide caps into the correct position for simultaneous and accurate cap closure. The system filters up to eight samples at once, without a power supply or a vacuum pressure source. Single-use filter units are optimized for solvents and aqueous solutions at volumes between 60 µL and 600 µL.

Process Control Software Automates Step-Testing Activities
When a process significantly changes, engineers conduct step-testing to understand the effects each process variable has on other process variables. This requires a series of small changes, and it can be time-consuming to collect data, build algorithms, and generate dynamic models. Pavilion8 Version 5.12 model predictive control (MPC) software empowers engineers to design and execute step-tests faster, more safely, and more accurately. Unlike manual step-testing that must be continuously monitored on-site, the Step Test Assistant independently makes adjustments in a test environment to identify models that drive operations to their best performance faster. Tests can be completed as much as 30% faster than manual testing. The software features Windows-based configuration and support, a multivariable run-time controller, continuous controller monitoring, and support for current browsers and operating systems.
