BioLegend — Premium Antibodies & Life Science Reagents

BioLegend is a global leader in the development and manufacture of high-quality antibodies, recombinant proteins, kits, and reagents for life science research. Founded in 2002 and headquartered in San Diego, California, BioLegend has grown into one of the most cited reagent suppliers in the world — with over 34,000 products referenced in more than 30,000 peer-reviewed publications across 190+ countries.

In 2021, BioLegend was acquired by PerkinElmer for $5.25 billion and now operates as part of Revvity, a global health science company. Despite this integration, BioLegend continues to operate under its own brand, maintaining the same product portfolio, quality standards, and commitment to innovation that researchers have relied on for over two decades.

BioLegend's product expertise spans immunology, oncology, neuroscience, stem cell biology, and cell biology. Whether you need a straightforward flow cytometry antibody or a cutting-edge single-cell multiomics reagent, BioLegend offers validated, publication-ready solutions at outstanding value.

BioLegend Product Lines: Antibodies, LEGENDplex™, TotalSeq™, MojoSort™ & More

BioLegend's portfolio is organized into focused product lines, each designed to address specific research workflows. Below is an overview of the core product categories available through Iright.

Antibodies BioLegend's antibody catalog is one of the most comprehensive in the industry, covering thousands of human, mouse, and rat targets. Products are available in a wide range of formats — purified, biotinylated, and directly conjugated to fluorophores including PE, APC, FITC, PerCP, and the proprietary Brilliant Violet™ series. Applications include flow cytometry, immunohistochemistry (IHC), immunofluorescence (IF), Western blotting (WB), and mass cytometry (CyTOF).

Brilliant Violet™ — Next-Generation Fluorescent Dyes Introduced in 2011 and developed using Nobel Prize-winning polymer chemistry, the Brilliant Violet™ dye series delivers exceptional brightness and photostability for flow cytometry panel design. BV421, BV510, BV605, BV711, and BV785 are among the most widely adopted fluorophores in high-parameter panels, enabling sharper resolution and reduced spectral spillover compared to conventional dyes.

TotalSeq™ — Antibody-Oligonucleotide Conjugates for Single-Cell Multiomics TotalSeq™ is BioLegend's proprietary platform for simultaneous protein and RNA detection at the single-cell level. Compatible with 10x Genomics and other leading sequencing platforms, TotalSeq™ reagents integrate seamlessly into CITE-seq and related workflows. Available in three formats — TotalSeq™-A, -B, and -C — to match different sequencing chemistries and capture methods.

LEGENDplex™ — Multiplex Bead-Based Immunoassays LEGENDplex™ enables quantification of up to 13–14 soluble analytes simultaneously in a single sample using a standard flow cytometer. Pre-designed panels cover human and mouse cytokines, chemokines, growth factors, and more. Custom panels are also available. This platform is an efficient alternative to multi-tube ELISA for cytokine profiling and immune monitoring.

MojoSort™ — Magnetic Cell Separation MojoSort™ is BioLegend's magnetic bead-based cell isolation system, designed for high-purity and high-yield separation of target cell populations. The system supports both positive and negative selection protocols for T cells, B cells, NK cells, monocytes, and more from human or mouse samples. MojoSort on Columns™ extends the platform with a column-based format compatible with third-party systems.

Recombinant Proteins & Cytokines BioLegend offers a broad range of recombinant proteins, including interleukins, interferons, growth factors, and chemokines for use in cell culture stimulation, functional assays, and ELISA standard preparation. All proteins are functionally validated and available in research-grade and carrier-free formats.

ELISA Kits & LEGENDScreen™ ELISA kits from BioLegend provide sensitive, reproducible quantification of specific targets in serum, plasma, cell culture supernatants, and other biological matrices. LEGENDScreen™ kits offer a broader screening approach, enabling rapid immunophenotyping of large marker panels from a single sample.

Cell Biology Reagents This category includes apoptosis detection kits (Annexin V), cell viability dyes, cell proliferation assays, fixation/permeabilization buffers, and isotype controls. These reagents are validated for use across flow cytometry, microscopy, and functional assay workflows.
