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".

Specificity and Use
Recognizes human C-peptide. C-peptide is a 31 amino acid peptide released when proinsulin is split into insulin and C-peptide. Proinsulin is split when it is released from the pancreas into the blood in response to a rise in serum glucose levels. C-peptide function is not fully understood, it binds to cell membranes which leads to increased intracellular Ca2+ concentration and subsequent stimulation of N+, K+-ATPase and endothelial nitric oxide synthase activities. C-peptide also functions in repair of the muscular layer of arteries. Levels of C-peptide can be used to distinguish between type 1 and type 2 diabetes. Patients with type 1 diabetes will usually have decreased levels of C-peptide, while patients with type 2 diabetes will have normal or higher than normal levels. Recognizes free C-peptide and proinsulin. It does not cross-react with human, bovine, porcine, mouse or rat insulin.
