academia only

分子别名（Synonym）

GDNF, ATF

表达区间及表达系统（Source）

Human GDNF Protein (E. coli), Research Grade (GDF-H5119) is expressed from E. coli cells. It contains AA Ser 78 - Ile 211 (Accession # P39905-1).

Predicted N-terminus: Met

蛋白结构（Molecular Characterization）

This protein carries no "tag".

The protein has a calculated MW of 15.2 kDa. The protein migrates as 15 kDa±3 kDa under reducing (R) condition, and 30 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under non-reducing (NR) condition (SDS-PAGE).

内毒素（Endotoxin）

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

纯度（Purity）

>95% as determined by SDS-PAGE.

制剂（Formulation）

Lyophilized from 0.22 μm filtered solution in 20 mM Sodium Citrate, 150 mM NaCl, pH4.0 with trehalose as protectant.
