Commonly used in FCM, Isotype Control applications. Typical workflows include Select staining controls in cells\/tissues (isotype\/KD\/KO), Phenotype target-positive cells by flow cytometry in PBMCs\/cell suspensions, Optimize antibody dilution for staining in cells\/tissues using a reference sample, QC lot-to-lot by comparing signal in a reference lysate or cell line.

They are used to estimate non‑specific binding and background signal in immunoassays. In flow cytometry and immunofluorescence, isotype controls can help identify staining driven by Fc receptor interactions, sticky epitopes, or fluorophore\/label-associated background rather than true antigen recognition. When conjugated, the isotype control should be used with the same fluorophore\/label and at the same concentration as the corresponding test antibody. This reagent is characterized by its host species (Human), isotype (IgG), which should match your primary antibody format as closely as possible.\u003c\/p\u003e\n\n\u003ch3\u003eHow this reagent helps\u003c\/h3\u003e\n\u003cp\u003eUse this isotype control to estimate non-specific background under matched staining conditions.
