• Cat.No.: CD19-4660H
• Product Overview: Site-specific APC-Labeled Active Recombinant Human CD19 protein(P15391-1)(Pro 20 - Lys 291), fused with C-terminal His tag, was expressed in HEK293.

Specification

• Source: HEK293
• Species: Human
• Tag: C-His
• Protein length: Pro 20 - Lys 291
• Conjugation/Label: Site-specific APC
• Form: Lyophilized from 0.22 μm filtered solution in PBS, 0.5% BSA, pH7.4.
• Bio-activity: 5e5 of anti-CD19 CAR-293 cells were stained with 100 μL of 1:50 dilution (2 μL stock solution in 100 μL FACS buffer) of APC-Labeled Human CD19 (20-291), His Tag and negative control protein respectively. APC signal was used to evaluate the binding activity.
