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".

Biologically Active Proteins

bioactive proteins
LSBio’s biologically active proteins have been tested to confirm that they retain their functional attributes. Each protein is uniquely tested based upon its particular function, such as measuring the ability of an enzyme to hydrolyze a substrate, using a cell proliferation assay to test a growth factor, or a cytotoxicity assay to test proteins that can cause cell death. These proteins are a cost-effective resource for use in a wide variety of in vitro research applications.
