表达区间及表达系统（Source）

Human DLL1 Protein, Fc Tag, premium grade (DL1-H5259) is expressed from human 293 cells (HEK293). It contains AA Gln 18 - Gly 540 (Accession # O00548-1).

Predicted N-terminus: Gln 18

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.

蛋白结构（Molecular Characterization）

This protein carries a human IgG1 Fc tag at the C-terminus.

The protein has a calculated MW of 82.8 kDa. The protein migrates as 103 kDa±5 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素（Endotoxin）

Less than 0.01 EU per μg by the LAL method / rFC method.

无菌（Sterility）

Negative

支原体（Mycoplasma）

Negative

纯度（Purity）

>90% as determined by SDS-PAGE.

>90% as determined by SEC-MALS.

制剂（Formulation）

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
