Recombinant Human SELM protein(Ala24-Leu145), His-tagged

• Cat.No.: SELM-550H
• Product Overview: Recombinant Human SELM (Q8WWX9) (Ala 24-Leu 145) was expressed in E. coli, fused with a polyhistidine tag at the C-terminus and an initial Met at the N-terminus.

Specification

• Source: E. coli
• Species: Human
• Tag: C-His
• Protein length: Ala24-Leu145
• Form: Lyophilized from sterile 50mM Tris, 50mM NaCl, 50mM Arg, 0.3% Tween 20, 5% glycerol, pH 8.5 Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Molecular Mass: The recombinant human SELM comprises 133 amino acids and has a calculated molecular mass of 15.4KDa. It migrates as an approximately 19 kDa band d in SDS-PAGE under reducing conditions.
• Purity: > 97 % 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°C before opening to recover the entire contents.
