Recombinant Human MS4A1 protein, His/trxA-tagged
Recombinant Human MS4A1(Ile 141 - Tyr 184) fused with His/trxA tag at N-terminal was expressed in E. coli.
Predicted N Terminal:
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally Mannitol or Trehalose are added as protectants before lyophilization.
Has a calculated MW of 22.3 kDa. The reducing (R) protein migrates as 25 kDa in SDS-PAGE .
Ile 141 - Tyr 184
Less than 1.0 EU per μg of the Human MS4A1 Protein, His Tag by the LAL method.
>90% as determined by SDS-PAGE.
Avoid repeated freeze-thaw cycles.No activity loss was observed after storage at:In lyophilized state for 1 year (4 centigrade); After reconstitution under sterile conditions for 3 months (-70 centigrade).
