BioLegend is a life science reagent manufacturer specializing in antibodies and research tools for immunology, cell biology and protein analysis. The brand is particularly well known for its extensive selection of fluorophore-conjugated antibodies used in flow cytometry and immune cell characterization.

Its antibody portfolio includes primary antibodies, secondary antibodies, functional-grade antibodies and conjugated antibodies covering a wide range of cell-surface, intracellular and secreted targets. Researchers can select antibodies according to target, clone, species reactivity, application and fluorophore, making BioLegend especially suitable for multicolor flow cytometry panel design.

BioLegend offers conjugates spanning ultraviolet, violet, blue, yellow-green and red laser configurations. Its antibodies, viability dyes, fixation and permeabilization buffers, compensation controls and staining reagents support complete flow cytometry workflows, including immunophenotyping, intracellular cytokine staining, phospho-flow analysis and cell-cycle studies.

Immunoassays are another important part of the BioLegend portfolio. The company supplies LEGEND MAX ELISA kits, ELISA MAX sets and LEGENDplex bead-based multiplex assays. These products support the measurement of cytokines, chemokines, growth factors and other soluble biomarkers. LEGENDplex assays use flow cytometry to quantify multiple analytes within the same sample, making them useful when sample volume is limited or several biomarkers must be analyzed simultaneously.

Beyond antibodies and immunoassays, BioLegend provides recombinant cytokines, chemokines, growth factors, functional proteins, magnetic cell-separation products, cellular dyes and cell-function assays. Its TotalSeq oligonucleotide-conjugated antibodies support multiomic workflows that combine single-cell protein and gene-expression analysis.

BioLegend products are widely used in innate and adaptive immunology, cancer and immuno-oncology, infectious disease research, neuroscience, stem cell biology and inflammation. Common applications include immune cell phenotyping, T-cell and B-cell analysis, cytokine detection, tumor microenvironment studies, apoptosis, cell viability, cell signaling and biomarker discovery.

Biolterna helps international laboratories and distributors source BioLegend products according to the required catalog number, clone, fluorophore, species reactivity, application and package size. Customers can send us an individual BioLegend catalog number or a complete antibody panel to check pricing, availability, lead time and international shipping options. We can also help compare alternative antibodies based on target, clone, conjugate and validated application.
