GDF-8, Myostatin, GDF8, MSTN, Growth, differentiation factor 8
Human latent GDF-8, His Tag (GD8-H5243) is expressed from human 293 cells (HEK293). It contains AA Asn 24 - Ser 375 (Accession # O14793-1).
Predicted N-terminus: His
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.
Less than 0.01 EU per μg by the LAL method / rFC method.
>90% as determined by SDS-PAGE.
>95% as determined by SEC-MALS.
Lyophilized from 0.22 μm filtered solution in PBS, 0.2 M Arginine, pH7.4 with trehalose as protectant.
