  • Immunohistochemistry Services

  • Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting immunostaining in relation to complex human pathologies.

  • TCR Screening Services

  • Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding. Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".

We have a collection of 529,578 monoclonal and polyclonal antibodies to most target proteins. They cover all major research species, applications, and are available in multiple conjugated forms. Our IHC-plus™ antibodies are highly characterized for use in FFPE human tissue Immunohistochemistry.

ELISA and Assay Kits
ELISA and Assay Kits

Our traditional Sandwich, Competitive EIA, and Direct ELISA kits provide a means to quantitatively measure thousands of targets of interest, while our Cell-Based and DNA-Binding ELISA kits are ideal for in-vitro studies and transcription factor analysis. Chemiluminescent CLIA kits provide high-sensitivity detection of low-copy targets and our Development kits enable researchers to cost-effectively run large numbers of assays. Our growing collection of Assay kits provide researchers with the means to monitor a variety of biological processes, such as apoptosis, cell proliferation, metabolism, and more.


Proteins can be used in a wide variety of applications, such as for the development of functional assays, small-molecule screening, receptor activation in-situ, or simply as controls for a Western Blot. We offer extracted native proteins and recombinant proteins in the form of cell lysates, or purified from bacterial or mammalian expression systems. Many proteins are bio-active and certified low-endotoxin.


Featured product categories including agonists, antagonists, inhibitors and modulators for your biomedical research needs. High quality products are available for use in cancer research, cardiovascular disease, cell biology, lipid research, immunology, metabolism, neuroscience, oxidative injury, and toxicology.
