Sample Preparation

Protein sample preparation kit for mass spectrometry

The new Pierce Mass Spec Sample Prep Kit for Cultured Cells provides the components needed to generate consistent and reproducible protein digests that are directly compatible with LC-MS workflows. The digests do not require further processing, such as C18 clean up or detergent removal.

Eliminate endotoxins from various protein sources, sizes and charges

Traditional endotoxin removal methods require significant optimization for every target molecule being purified. Furthermore, ionic methods for binding endotoxins require pH optimization to avoid binding highly charged proteins, and size-exclusion methods to filter endotoxins are not effective for large proteins. In this Product Article about removing endotoxins from samples, our scientists demonstrate how they used

Removing endotoxins from protein samples

Endotoxin removal during the development of biological therapeutics is critical for preventing inflammation, tissue death and endotoxin shock. In this Product Article about removing endotoxins, our scientists discuss how they evaluated a spin-column method that is ideal for protein samples.

Introducing Detergent Removal Resin for Low Concentration Protein Sample Cleanup

ROCKFORD, Ill.
