The activity of Alexa Fluor 488-Labeled Human Mesothelin (296-580), His Tag (Cat. No. MSN-HA2H9) was higher than other Competitor.
5e5 of anti-MSLN CAR-293 cells were stained with 100 μL of 3 μg/mL of AF488-Labeled Human Mesothelin (296-580), His Tag (Cat. No. MSN-HA2H9) and negative control protein respectively (Fig. C and B), and non-transfected 293 cells were used as a control (Fig. A). AF488 signal was used to evaluate the binding activity (QC tested).
5e5 of PBMCs were stained with AF488-Labeled Human Mesothelin (296-580), His Tag (Cat. No. MSN-HA2H9) and anti-CD3 antibody, washed and then analyzed with FACS. PE signal was used to evaluate the expression of CD3+ T cells in PBMCs, and AF488 signal was used to evaluate the non-specific binding activity to PBMCs (QC tested).
