REAfinity™ Recombinant Antibodies: Superior Quality, Zero Background Analysis

REAfinity™ recombinant antibodies represent a groundbreaking advancement in flow cytometry analysis, engineered with specifically mutated human IgG1 Fc regions to completely eliminate Fcγ receptor binding and achieve true zero background signals. This innovative technology fundamentally solves the persistent background signal problems that have long plagued flow cytometry applications, delivering unprecedented clarity and accuracy in cellular analysis.

The cornerstone of REAfinity™ technology lies in its sophisticated Fc region engineering, where precise mutations are introduced to the human IgG1 framework to abolish any interaction with Fcγ receptors while maintaining optimal antigen binding characteristics. This revolutionary approach ensures that researchers can achieve crisp, clean data with minimal non-specific binding, particularly crucial when analyzing cell populations with high Fcγ receptor expression such as macrophages, dendritic cells, and B cells.

One of the most significant advantages of REAfinity™ antibodies is the implementation of a single, universal human IgG1 isotype control across the entire product range. This standardization dramatically simplifies experimental design, reduces costs, and eliminates the complexity of managing multiple isotype controls, allowing researchers to focus on their scientific objectives rather than experimental logistics.
