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".
Determined by the stimulation of IL-12 induction by human peripheral blood mononuclear cells (PBMC) and the stimulation of IL-8 induction by human PBMC. The expected ED50 for this effect is 5-10 ng/ml. Note: results may vary with PBMC donors.
Less than 0.1 ng/µg of protein.
Lyophilized from 10 mM sodium phosphate, pH 7.5
Reconstitute in 5-10 mM Sodium Phosphate, pH 7.5, to 0.1-1.0 mg/ml. The solution can then be diluted into other aqueous buffers or stored at 4°C for 1 week or -20°C for future use
TNFSF5 is expressed on the surface of T cells. It regulates B cell function by engaging CD40 on the B cell surface. A defect in this gene results in inability of immunoglobulin class switch and is associated with hyper IgM syndrome.
