Other Tags and Version Biotin & Other Labeled Version
This protein carries a polyhistidine tag at the N-terminus. Pro-GDF8 was predominantly migrated to 45-50 kDa precursor monomers, and latent GDF8 showed 35 kDa prodomain monomer bands together with a 14 kDa growth factor monomer when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE).
The protein is designed as a dimer.
Endotoxin
Less than 0.01 EU per μg by the LAL method / rFC method.
Purity
>90% as determined by SDS-PAGE.
>95% as determined by SEC-MALS.
Formulation
Lyophilized from 0.22 μm filtered solution in PBS, 0.2 M Arginine, pH7.4 with trehalose as protectant.
