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".
Hepatocyte nuclear factor 4 alpha (HNF4 alpha), a NR2 Hepatocyte NF4-Like receptor, is a liver-enriched transcription factor that is involved in the expression of liver-specific genes. HNF4 alpha controls the expression of transcription factor HNF1, which is important in the expression of hepatic genes, including those involved in glucose, cholesterol, and fatty acid metabolism.
