>Heavy Labeled Proteins
>Human HER2 /ErbB2 MS Standard Protein, C13 and N15-labeled
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 70.2 kDa. The protein migrates as 110-115 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
HER2 / ErbB2, Heavy Labeled is labeled with [U- 13C6, 15N4]-L-Arginine and [U- 13C6, 15N2]-L-Lysine
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
