Protocol

High-Throughput Detection of Degraded Polysorbate in Biological Formulations with FMM

Excipients like polysorbate are used in the majority of biologic products to improve stability. However, the polysorbate itself can degrade, impairing the stability of the API and contributing an additional aggregate source that can elicit an immunogenic response. Traditionally, monitoring only poly... More


Protocol

Transfecting Edit-R™ Cas9 mRNA with Synthetic Guide RNA in Cultured Mammalian Cells

This is an abbreviated protocol for transfecting Edit-R™ Cas9 mRNA (Cat #CAS11195, #CAS11859, or #CAS11860) with synthetic guide RNA into cultured mammalian cells using DharmaFECT™ Duo transfection reagent (Cat #T-2010-xx). Synthetic guide RNA can be either synthetic single guide RNA, or synthetic c... More

Investigating the increased lifespan in C. elegans daf-2 mutants by 4D-Lipidomics™

The small nematode Caenorhabditis elegans is one of the premier biomedical model organisms and employed in many aspects of basic and applied science.... More


Protocol

Next-generation MALDI top-down sequencing of protein biotherapeutics – expanding the scope of timsTOF technology

This new method takes advantage of Trapped Ion Mobility Spectrometry (TIMS), to further enhance MALDI-TDS by adding another dimension of separation in the gas phase.High confidence N- and C-terminal sequencing specifically are enhanced by combining high resolution (~ 60,000 RP) and 2 ppm mass accura...

Protocol

Achieving Reproducible and Automated Region-Specific Lipid Annotations using CCS-aware SpatialOMx®

The CCS-aware SpatialOMx® workflow opens new dimensions by combining the molecular and spatial information measured by MALDI-TIMS Imaging with highly confident 4D-Omics annotations. MetaboScape® 2021b and SCiLS™ Lab 2021a provide the interface to match data from both ionization techniques and enable... More
