Active Recombinant Human LAG3 Protein (Leu 23 - Leu 450), His-tagged, low endotoxin

• Cat.No.: LAG3-381H
• Product Overview: Recombinant Human LAG3 Protein, His-tagged, low endotoxin is expressed from human 293 cells (HEK293). It contains AA Leu 23 - Leu 450 (Accession # P18627). Predicted N-terminus: Leu 23. This protein carries a polyhistidine tag at the C-terminus, and has a calculated MW of 47.1 kDa. The predicted N-terminus is Leu 23. The reducing (R) protein migrates as 55-60 kDa in SDS-PAGE due to glycosylation.

Specification

• Source: HEK293

• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
• Bio-activity: Immobilized Anti-Human LAG3 MAb, Human IgG1 at 2μg/mL (100 μL/well) can bind Recombinant Human LAG3 Protein, His-tagged, low endotoxin with a linear range of 1-6 ng/mL (QC tested).
• Molecular Mass: 47.1 kDa
• Protein length: Leu 23 - Leu 450
• Endotoxin: Less than 0.01 EU per μg by the LAL method.
• Purity: >90% as determined by SDS-PAGE.
• Notes: Please avoid repeated freeze-thaw cycles.
• Stability: No activity loss is observed after storage at:
  4-8 centigrade for 12 months in lyophilized state;
  -70 centigrade for 3 months under sterile conditions after reconstitution.
• Storage: For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 mg/ml. Centrifuge the vial at 4 centigrade before opening to recover the entire contents.
