Recombinant Mouse CSK Protein, GST & His-tagged
Recombinant mouse CSK (P41241?) (Met 1-Leu 450) was fused with the N-terminal polyhistidine-tagged GST tag at the N-terminus.
Predicted N Terminal:
Supplied as sterile 20mM Tris, 500mM NaCl, pH 8.0, 10% glycerol.
The specific activity was determined to be 70 nmol/min/mg using Poly(Glu,Tyr) 4:1 as substrate.
The secreted recombinant mouse CSK/GST chimera consists of 687 amino acids and has a calculated molecular mass of 78.5 kDa. The recombinant protein migrates as an approximately 65 kDa band in SDS-PAGE under reducing conditions.
< 1.0 EU per μg of the protein as determined by the LAL method.
>85 % as determined by SDS-PAGE.
Samples are stable for up to twelve months from date of receipt at -70ºC.
Store it under sterile conditions at -20ºC~-70ºC. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
