  • 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".

LifeSpan BioSciences, Inc. (LSBio) provides high-quality antibodies and immunohistochemistry (IHC) data and services to researchers worldwide.

Founded in 1995 by Drs. Joseph Brown and Glenna Burmer, LSBio was established as a molecular pathology company with a focus on protein localization in diseased human tissues by IHC. Through the experience gained by executing thousands of IHC studies, and generating and testing many thousands of antibodies, LSBio has become a world leader in the antibody industry, with a reputation for excellence. LSBio has a catalog of 125,800 monoclonal and polyclonal antibodies to 19,580 targets. Antibodies are available for most species and all major research applications, such as immunoblotting, IHC, immunofluorescence, and fluorescence-activated cell sorting. Through extensive ongoing in-house testing, more than 9,750 of these antibodies have also been identified as exceptional IHC reagents, and given the IHC-plus™ brand.  For more than a decade researchers have been relying upon LSBio’s expertise to fulfill their molecular pathology outsourcing needs. LSBio’s services include: antibody production and characterization, custom IHC studies supported by a massive archival human tissue bank, tissue-cross reactivity screening, and standard histology procedures and pathology analysis. LSBio stands behind the quality of its products and services and offers unparalleled customer service and support. In the years to come, LSBio plans to continue expanding its catalog of high-quality proteomics products, with a focus on IHC-validated antibodies, providing its customers with excellent reagents, services, and support to accelerate their research.
