General assays are standardized test procedures for detecting or quantifying biomarkers, active agents, and biological molecules in molecular biology, diagnostics, and biochemical research. Select methods by target analyte, measurement principle, sensitivity, specificity, equipment compatibility, throughput, and sample requirements; common principles include enzymatic, fluorescence-based, and cell-based tests.
View product category →ELISA kits enable detection and quantitative measurement of specific antigens or antibodies in biological samples for diagnostics, research, quality control, and bioprocess monitoring. Choose according to analyte, sample matrix, assay format, sensitivity, and instrument compatibility; sandwich assays can increase specificity.
View product category →Recombinant proteins and peptides support molecular biology, diagnostics, biochemical, and pharmaceutical applications as reference materials, ligands, substrates, or immunoreactants. Select according to expression source, construct format, purity, specificity, and functionality; consider post-translational modification requirements, endotoxin status, and storage needs.
View product category →Monoclonal antibodies are highly specific immune proteins that bind a single antigen epitope, supporting molecule identification in diagnostics and research, including immunophenotyping and flow cytometry. Select for target specificity, affinity, epitope, isotype, application validation, formulation, and detection-method compatibility; antigen alterations may reduce binding.
View product category →Polyclonal antibodies are heterogeneous serum-derived antibody mixtures that recognize multiple antigen epitopes, supporting immunoprecipitation, Western blot, immunofluorescence, and ELISA. Select according to host species, target, antigen form, specificity, affinity, and cross-reactivity; document batch changes, as binding characteristics may vary.
View product category →Recombinant antibodies are genetically engineered immunologically active proteins used in research, diagnostics, and biopharmaceutical development, including immunoassays and therapeutic protein building blocks. Select formats and expression systems according to epitope specificity, affinity, stability, and glycosylation, as these can affect binding and biological activity.
