Recombinant Human CD19 protein, His-tagged, FITC-labelled

• Cat.No.: CD19-3211H
• Product Overview: FITC-labelled Recombinant Human CD19 protein(P15391-1)(Pro20-Lys291), fused with C-terminal His tag, was expressed in HEK293.

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: Pro20-Lys291
• Tag: C-His
• Conjugation/Label: FITC
• Form: Supplied as 0.22μm filtered solution in PBS (pH 7.4).
• Bio-activity: Use 100 μl FITC-Compatible Human CD19 (10 μg/ml) to detect the positive rate of 1脳10^6 anti-CD19 CAR cells and FITC-labeled irrelevant protein (100 μl, 10 μg/ml) was served as a negative control.
• Molecular Mass: The protein has a predicted MW of 60.1 kDa. Due to glycosylation, the protein migrates to 68-72 kDa based on Tris-Bis PAGE result.
• Endotoxin: Less than 1EU per μg by the LAL method.
• Purity: > 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
• Storage: Valid for 12 months from date of receipt when stored at -80°C; Recommend to aliquot the protein into smaller quantities for optimal storage. Please do not 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.
