表达区间及表达系统（Source）
Human IL17A, premium grade (ILA-H5219) is expressed from human 293 cells (HEK293). It contains AA Gly 24 - Ala 155 (Accession # Q16552-1).
Predicted N-terminus: Gly 24
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.
Request for sequence蛋白结构（Molecular Characterization）
This protein carries no "tag".
The protein has a calculated MW of 15.1 kDa. The protein migrates as 16 kDa, 17 kDa and 19 kDa under reducing (R) condition, and 27-34 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.
