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.
Source : HEK293
Species : Human
Tag : Fc
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.
