Active Recombinant Human MS4A1 Protein (Ile141-Ser188), TrxA-tagged, Biotinylated

• Cat.No.: MS4A1-470H
• Product Overview: Recombinant Human MS4A1 Protein (NP_068769.2) (Ile141-Ser188) was produced by E. coli expression system. This protein was expressed with a TrxA tag at the N-terminus. The purified protein was biotinylated in vitro.

Specification

• Species: Human
• Source: E.coli
• Tag: TRxA
• Protein Length: Ile141-Ser188
• Form: Lyophilized from sterile 50 mM Tris, pH 8.0.
  Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Bio-activity: Using the Octet RED System, the affinity constant (Kd) of CD20 Protein, Human, Recombinant (TrxA Tag), Biotinylated bound Mabthera was 0.04 μM.
• Molecular Mass: The recombinant human MS4A1 consists of 218 amino acids and predicts a molecular mass of 23.9 kDa.
• Purity: > 80 % as determined by SDS-PAGE
• Storage: Samples are stable for up to twelve months from date of receipt at -20°C to -80°C
  Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4℃ before opening to recover the entire contents.
