Recombinant Human GALNT13(Ser29-Thr556) fused with His tag at C-terminal was expressed in HEK293.
Predicted N Terminal:
Supplied as a 0.2 μm filtered solution in Tris and NaCl.
Measured by its ability to transfer GalNAc from UDP-GalNAc to peptide EA2. The specific activity is >600 pmol/min/μg.
Predicted Molecular Mass: 61 kDa;
SDS-PAGE: 60-70 kDa, reducing conditions.
<1.0 EU per 1 μg of the protein by the LAL method.
>95%, by SDS-PAGE visualized with Silver Staining and quantitative densitometry by Coomassie® Blue Staining.
Avoid repeated freeze-thaw cycles.
6 months from date of receipt, -20 to -70 centigrade as supplied.
3 months, -20 to -70 centigrade under sterile conditions after opening.
