Services
  • 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".

Animal-Free Proteins

animal-free proteins
Animal-free proteins offer an alternative to researchers concerned about the experimental variables caused by the use of reagents containing trace animal components and mammalian pathogens. All of our animal-free proteins are manufactured in dedicated facilities using only animal-free reagents and components. Animal-free proteins have comparable biological activity and purity to animal-derived proteins produced using standard techniques.
