Recombinant Human CD19 Protein (Pro 20 - Lys 291), Fc-tagged, FITC-Labeled

• Cat.No.: CD19-341H
• Product Overview: Recombinant Human CD19 Protein, Fc-tagged, FITC-Labeled is expressed from human HEK293 cells. It contains AA Pro 20 - Lys 291 (Accession # P15391-1). It is the FITC labeled form of Human CD19 (20-291), Fc Tag. Predicted N-terminus: Pro 20. This protein carries a human IgG1 Fc tag at the C-terminus. The protein has a calculated MW of 56.6 kDa. The protein migrates as 70 kDa and 150 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation. Conjugate (FITC): Excitation source: 488 nm spectral line, argon-ion laser; Excitation Wavelength: 488 nm; Emission Wavelength: 535 nm.

Specification

• Source: HEK293
• Species: Human

• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
• Molecular Mass: 56.6 kDa
• Protein length: Pro 20 - Lys 291
• Endotoxin: Less than 1.0 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.
