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.
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".

SLC7A11 / XCT antibody was raised against synthetic 19 amino acid peptide from N-terminus of human SLC7A11. Percent identity with other species by BLAST analysis: Human, Gorilla, Orangutan, Gibbon (100%); Monkey, Marmoset (95%); Horse (89%); Rat, Dog, Hamster (84%).
LS-E28749 - Liquid - 50 µg - $145.00
Immunizing peptide used to generate LS-A3434. Useful for pre-absorption and neutralization of the antibody's antigen binding site.
Human SLC7A11. BLAST analysis of the peptide immunogen showed no homology with other human proteins.
Immunohistochemistry: LS-A3434 was validated for use in immunohistochemistry on a panel of 21 formalin-fixed, paraffin-embedded (FFPE) human tissues after heat induced antigen retrieval in pH 6.0 citrate buffer. After incubation with the primary antibody, slides were incubated with biotinylated secondary antibody, followed by alkaline phosphatase-streptavidin and chromogen. The stained slides were evaluated by a pathologist to confirm staining specificity. The optimal working concentration for LS-A3434 was determined to be 14-28 ug/ml.

SLC7A11 / XCT is a member of a heteromeric, sodium-independent, anionic amino acid transport system that is highly specific for cysteine and glutamate. In this system, designated Xc(-), the anionic form of cysteine is transported in exchange for glutamate. This protein has been identified as the predominant mediator of Kaposi sarcoma-associated herpesvirus fusion and entry permissiveness into cells.
