> IgG Isotype Controls
Antibody drugs have become an important field in the development of biomedicine. Isotype control antibodies in antibody drug development are of the same class and subtype as the primary antibody developed against the target, but do not specifically bind to a known or potential target. The purpose of using the isotype control is to confirm that the binding or effect of the primary antibody is specific, excluding non-specific interactions with Fc receptor proteins or with other proteins. Meanwhile, isotype control can also be used as an antibody that competes for binding to Fc receptor proteins, which is related to functional blocking antibody perform the same function, which facilitates effective and reasonable evaluation of the efficacy of antibody drugs. Non-specific background is an important variable that needs to be controlled. Setting the corresponding isotype control antibody to detect non-specific binding can reduce the generation of false positive results and evaluate the possible influencing factors accurately in the drug development process.
We offer high-performance wild-type and mutant antibody isotype controls designed to accelerate your research. The wild-type Fc maintains its native conformation for reliable foundational studies and control experiments. And our mutant Fc is engineered with clinically relevant modifications that precisely match the engineering requirements of over 20 marketed therapeutic antibody. These rigorously validated isotype controls deliver exceptional specificity and reproducibility, with no endogenous background interference, ensuring trustworthy results across FACS, ELISA, and SPR applications. Whether you're conducting basic research or developing next-generation biologics, our isotype controls provide the critical standardization needed to advance your antibody discovery, validation, and therapeutic development workflows with confidence.
Dual Fc Design - Flexible for Your NeedsWild-type Fc: Preserves native conformation, ideal for high-confidence controls
Mutant Fc: Engineered to match 20+ approved therapeutic antibodies
High ReproducibilityRigorous QC ensures batch-to-batch consistency
No endogenous background for reliable results
Ready-to-Use Multi-Tag SystemDirect compatibility with major platforms (FACS/ELISA/SPR)
