What we make

Purpose-built for
biologics pipelines

Protein A/G/L Resins

High-capacity affinity resins engineered for consistent IgG and Fc-fusion capture across discovery and process development workflows.

Custom Affinity Matrices

Ligand-coupled agarose and magnetic bead formats for target-specific purification of antibodies, enzymes, and recombinant proteins.

Fluorescence Control Beads

Multi-intensity bead sets calibrated across the visible spectrum — optimized for flow cytometry, imaging cytometry, and multiplex assay platforms.

Assay Standards & QC Sets

Lot-to-lot consistency reference materials for instrument standardization, panel optimization, and inter-lab reproducibility programs.

About us

Science you can
build on.

Pacific Immunogel was founded by researchers who understood that the tools behind great science need to be as rigorous as the science itself. We develop and manufacture bioanalytical products that meet the demands of both early discovery and regulated quality control environments.

Our protein purification portfolio is designed around real workflow bottlenecks — maximizing yield, minimizing impurities, and giving teams the reproducibility they need to move faster. Our fluorescence control beads are manufactured under tight spectral tolerances, making them reliable reference points across platforms and laboratories.

Our commitments

  • Reproducibility first. Every product is batch-validated against reference standards before release.
  • Platform agnostic. Our beads and resins are tested across major cytometry and chromatography systems.
  • Responsive support. Direct access to our scientific team — not a call center.
  • Custom capabilities. Unique coupling chemistries and bead formats available for specialized applications.
  • Regulatory readiness. Documentation packages available for GxP environments.
