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".
Purified / Lyophilized / Biologically Active / Endotoxin Level: Less than 0.02 EU/µg protein (determined by LAL method).
FASLG / Fas Ligand
17.7 kDa. Protein migrates as 25-32 kDa in reduced SDS-PAGE due to glycosylation
HEK 293 Cells
Greater than 95% by SDS-PAGE
Measured by its ability to induce apoptosis of Jurkat human acute T cell leukemia cells. The ED50 for this effect is typically 0.1-1.5 ng/mL in the presence of 10 µg/mL of a crosslinking antibody Mouse Anti poly-Histidine Monoclonal Antibody.
Less than 1.0 EU/µg protein (determined by LAL method).
Lyophilized from 50 mM Tris, 100 mM glycine, pH 7.0, mannitol or trehalose
Centrifuge the vial before opening. Reconstitute in sterile PBS, pH 7.4 to 50 µg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 month. For extended storage, store at -20°C.
Cytokine that binds to TNFRSF6/FAS, a receptor that transduces the apoptotic signal into cells. May be involved in cytotoxic T-cell mediated apoptosis and in T-cell development. TNFRSF6/FAS-mediated apoptosis may have a role in the induction of peripheral tolerance, in the antigen-stimulated suicide of mature T-cells, or both. Binding to the decoy receptor TNFRSF6B/DcR3 modulates its effects.
