Click & Execute Method
This advanced method offers an end-to-end solution developed around an advanced application, a specialized kit, or an analytical system. It delivers complete functional, ready-to-use protocols that are qualitatively and quantitatively assessed for consistency, executability, and repeatability, usually without needing to make any changes. It operates per batch size and is scalable to accommodate changing requirements.

The task of accurately separating, identifying, and quantitating amino acids in the research, development, and commercialization of food, feed, and biotherapeutic products is challenging. To analyze released amino acids by HPLC or UPLC, Waters provides many solutions that use pre-column derivatization so that amino acids can be analyzed by optical detection.

Tutorial Method
This basic method provides the core methodology for translating a workflow into OneLab-executable script(s) as an attempt to fully or semi-automate a specific procedure. It demonstrates the benefits of automation and highlights OneLab capabilities and best practices to promote solution adoption, helping transition from manual to a more automated approach. It can be used alone or serves as a building block for a more complex workflow and is easily adaptable to users' requirements.

Bottom-up proteomics is a useful approach for the discovery of signature peptides to identify specific proteins found in the complex food matrix. Here we present a fully automated sample preparation protocol for protein digestion using the ProteinWorks kit, and the final mixture obtained will be ready for a typical LCMS method.

The European Food Safety Authority (EFSA) predicts that PFAS exposure is primarily through food. Milk, being the staple food product for toddlers and children, would affect them disproportionately compared to adults, so there is a need to monitor PFAS levels in milk. In addition to using Andrew+ and Extraction+ for improved throughput and reduced errors, this method uses Oasis WAX SPE cartridges to enhance PFAS recovery and reduce matrix interferences for LC-MS/MS analysis. Automation also allowed for washing the walls of the sample vials with eluent, increasing the recovery of PFAS.

Get Started Method
This example method provides a freely adjustable framework for measuring the adaptability of the OneLab environment to workflows from different application fields. It helps to understand various nuances of the code-free, universal protocol designer and provides general indications as to the feasibility of a project. Scripts generally require fine adjustment to correct for variables and support specific labware implementation.
Version 2, 2 Oct 2022 at 8:16 AM
Adequate endotoxin testing is invaluable in ensuring quality and safety. LAL assays require cumbersome sample preparation and are easily disturbed by different constituents of the sample. EndoLISA, combining solid-phase format and synthetic rFC, achieves sensitive detection of endotoxin by eliminating interfering components. It can be automated, which accelerates the test with minimal human error.

Sandwich ELISA is the most robust and sensitive type of ELISA technique. ELISA protocols traditionally have a complex workflow that requires optimization to obtain accurate results with low analytical error. To maximize accuracy and reproducibility, OneLab can guide you through your optimized protocol to ensure consistent pipetting throughout the assay and between sample replicates.
