ELISA (Enzyme-Linked Immunosorbent Assay) is a complementary technology to bioassays as it is commonly used to quantify specific proteins or antibodies as part of a bioassay workflow. While ELISA provides quantitative data on specific components, bioassays often assess the overall biological effect of a substance or mixture.

CE (Capillary Electrophoresis) can be complementary to bioassays. CE is an analytical technique used to separate and quantify different components within a sample, such as proteins or DNA fragments. In the context of bioassays, CE can be used to characterize the components of a sample before or after the bioassay, offering information about its composition or the impact of the bioassay on the sample's components.

HPLC (High-Performance Liquid Chromatography) is a complementary technology to bioassays because it is used to separate, identify, and quantify components of a mixture. In the context of bioassays, HPLC can be used to prepare samples, purify compounds, or analyze the composition of a sample before or after the bioassay. It provides valuable information about the chemical characteristics of the substances being tested or produced, which complements the biological activity data obtained from bioassays.
