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.

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".

LSBio’s growing collection of Assay kits provide researchers with the tools necessary to monitor various biological processes in the course of their life science research, drug discovery & development, or environmental monitoring studies. Assay kits are available for monitoring cell proliferation, damage, and oxidative stress, cytotoxicity, apoptosis, metabolism, signaling pathways and signal transduction. Each kit includes all of the necessary reagents to conduct the assay, and a clear, detailed protocol. LSBio’s experienced technical staff is also available to address any questions researchers may have about each kit and how they may be used to generate optimal results.
