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".
Dehydroepiandrosterone (DHEA), and demonstrates some cross reactivity with DHEAS. Negligible cross reactivity has been observed with Progesterone and Testosterone. DHEA is the most abundant hormone in the human body and a precursor of all the sex hormones. It is synthesized principally in the adrenal glands and gonads from cholesterol, through conversion to pregnenolone and 17a-Hydroxypregnenolone, by the action of P450 enzymes. DHEA is mainly found in serum as the sulphated form (DHEAS), a reversible reaction catalyzed by sulfotransferase in the adrenal glands, liver and small intestine.
