BioLegend provides a wide selection of antibodies validated and quality-control tested for a variety of applications including Western Blot (WB), Immunohistochemistry (IHC), Immunocytochemistry (ICC), Immunoprecipitation (IP), or Chromatin IP (ChIP). Targets include a wide selection of cell biology proteins including cell signaling, cell structure, cell development and differentiation, cell proliferation and growth, cell cycle, epigenetic and transcriptional regulators, cell adhesion, and cell death proteins, as well as epitope tags.

Application Protocols

BioLegend’s Commitment to Antibody Quality


To ensure the highest quality of products, BioLegend’s cell biology antibodies undergo extensive validation processes, which include:


  • Testing on knockout (KO) or knockdown (KD) cell lysates (CRISPR/Cas9 or siRNA), and negative control cell lines to confirm antibody specificity.
  • Testing on multiple species (human, mouse, rat, yeast, bacteria, zebrafish) whenever applicable, to determine antibody cross-reactivity.
  • Side-by-side comparison testing with competitor’s antibody to ensure sensitivity.
  • Side-by-side comparison testing of lots with internal controls for lot-to-lot consistency.
  • Clones for one application (such as WB or ChIP) further validated in multiple applications (such as microscopy, flow cytometry) to provide the user the flexibility of supplementing their data with additional assays specific to their research.
  • Optimization of antibody suggested use by a titration range.

Go-ChIP-Grade™ Protein G Enzymatic Kit

BioLegend offers a variety of products to help perform effective ChIP assays. We offer high-quality Go-ChIP-Grade™ Purified Antibodies for ChIP assays directed toward diverse targets including histone modifications, chromatin-associated proteins, and transcription factors. We also offer a Go-ChIP-Grade™ Protein G Enzymatic Kit for a quicker, easier, and more efficient way to perform ChIP assays.



Direct-Blot™ HRP Antibodies

When performing western blots, it is common to use a secondary antibody to detect the proteins of interest. To help you perform western blots with ease, BioLegend offers Direct-Blot™ primary antibodies directly conjugated to horseradish peroxidase (HRP).


Prime-Step™ Prestained Broad Range Protein Ladder

The Prime-Step™ Prestained Broad Range Protein Ladder is a three-color protein standard with 10 prestained chromophore-conjugated recombinant proteins covering a wide range of molecular weights, from 6.5-270 kDa. It is ideal for monitoring protein separation during SDS-PAGE, confirming WB transfer on membranes, and estimating protein sizes.
