Activin A, INHBA
Human Activin A Protein (E. coli), premium grade (ACA-H5113) is expressed from E. coli cells. It contains AA Gly 311 - Ser 426 (Accession # P08476).
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.
This protein carries no "tag".
The protein has a calculated MW of 13.1 kDa. The protein migrates as 14 kDa±3 kDa under reducing (R) condition, and 25 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under non-reducing (NR) condition (SDS-PAGE).
Less than 0.01 EU per μg by the LAL method / rFC method.
