Identification of novel KRT32-associated proteins in primary keratinocytes cells lysate by GST-KRT32 pulldown assays coupled with mass spectrometry.

GST-KRT32 and its interacting proteins in primary keratinocytes cells were enriched by pull-down using glutathione-Sepharose beads. Then, KRT32-interacting proteins were identified by mass spectrum. Proteins obtained in Pulldown were subjected to SDS-PAGE gel electrophoresis and silver staining. The SDS-PAGE gel was sent to the mass spectrometry platform of the Jingjie PTM Biolab for subsequent processing and mass spectrometry detection.
