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 / Endotoxin Level: Less than 0.06 EU/µg protein (determined by LAL method).
CX3CL1 / Fractalkine
Greater than 97% by SDS-PAGE and HPLC
Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using human peripheral blood lymphocytes (PBL) is less than 0.5 µg/ml, corresponding to a specific activity of > 2000 IU/mg.
Tris buffer, 50% glycerol.
Reconstitute in sterile distilled water to 0.1-1 mg/ml.
Short term: -20°C; Long term: -80°C; Avoid freeze-thaw cycles.
CX3CL1/fractalkine is a chemokine with a unique CX3C motif. Fractalkine is synthesized in endothelial cells as a membrane protein, and the N-terminal domain containing a CX3C motif is cleaved and secreted. Fractalkine is the first described cell-surface anchored chemokine and has potent mononuclear cell-directed adhesion and chemotactic properties. Fractalkine is involved in the pathogenesis of various chronic inflammatory diseases, such as rheumatoid arthritis and atherosclerosis.
