| Background | Abatacept (CTLA4lg) is a soluble fusion protein consisting of the extra-cellular domain of human CTLA4 and a fragment of the Fc portion of human IgG1 (hinge and CH2 and 3 domains). Abatacept is a selective T-cell co-stimulation modulator and a protein agent for the autoimmune diseases. |

SEC-HPLC detection for Research Grade Abatacept.

Flow-cytometry using APC anti-human CD80 &/or CD86 antibody. Raji cells were stained with an irrelevant antibody (Blue Histogram) or an APC anti-human CD80 &/or CD86 monoclonal antibody (Catalog: HW630296, Yellow Histogram) at a concentration of 5 µg/ml for 30 mins at RT. After washing, cells analysed on a NovoCyte Flow Cytometer.

Flow-cytometry using PE anti-human CD80 &/or CD86 antibody. Raji cells were stained with an irrelevant antibody (Blue Histogram) or an PE anti-human CD80 &/or CD86 monoclonal antibody (Catalog: HW630296, Yellow Histogram) at a concentration of 5 µg/ml for 30 mins at RT. After washing, cells analysed on a NovoCyte Flow Cytometer.
