Active Recombinant Human FOLR2 protein, His-tagged

• Cat.No.: FOLR2-031H
• Product Overview: Recombinant Human FOLR2 (Thr17-His228) protein was fused to His-tag at C-terminus and expressed in human 293 cells (HEK293).

Specification

• Source: HEK293
• Species: Human
• Tag: His
• Form: Lyophilized from 0.22 μm filtered solution in Tris and Glycine, pH7.5. Normally trehalose is added as protectant before lyophilization.
• Bio-activity: Immobilized Folic acid-BSA conjugate at 5 μg/mL (100 μL/well) can bind Human FOLR2, His Tag with a linear range of 2-20 ng/mL.
• Molecular Mass: The protein has a calculated MW of 26.5 kDa. The protein migrates as 30-35 kDa under reducing (R) condition (SDS-PAGE) due to N-linked glycosylation which has been verified by PNGase F digestion.
• Protein length: Thr 17 - His 228
• Endotoxin: Less than 1.0 EU per μg by the LAL method.
• Purity: >90% as determined by SDS-PAGE.
• Storage: For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower.
  Please avoid repeated freeze-thaw cycles.
  This product is stable after storage at:
  -20 centigrade to -70 centigrade for 12 months in lyophilized state;
  -70 centigrade for 3 months under sterile conditions after reconstitution.
• 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.
