Yersinia pseudotuberculosis invasin (794-985) Protein, His Tag, premium grade (INN-Y5144) is expressed from E. coli cells. It contains AA Val 794 - Ile 985 (Accession # P11922-1).

Predicted N-terminus: Met

It is produced under our rigorous quality control system that incorporates a comprehensive set of tests including sterility and endotoxin tests. Product performance is carefully validated and tested for compatibility for cell culture use or any other applications in the early preclinical stage. When ready to transition into later clinical phases, we also offer a custom GMP protein service that tailors to your needs. We will work with you to customize and develop a GMP-grade product in accordance with your requests that also meets the requirements for raw and ancillary materials use in cell manufacturing of cell-based therapies.
