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".

Specificity and Use
STEAP1 / STEAP antibody was raised against an 18 amino acid peptide located near the c-terminal region of human STEAP1.
Recognizes STEAP1 (six transmembrane epithelial antigen of the prostate), a 39kD protein which is a member of a family of cell surface serpentine transmembrane antigens of the prostate. STEAP1 is predominantly expressed in human prostate and is up-regulated in several cancer lines including prostate, ovarian, cervical, breast, testicular, bladder, colon and Ewing sarcoma. It is significantly expressed at cell-cell junctions and has been shown to be a target of human CD8 T cells. This indicates that it could be used as a potential target for cancer immunotherapy. Does not cross-react with other STEAP-proteins.
Immunohistochemistry: LS-B2828 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-B2828 was determined to be 5 ug/ml. Western Blot: LS-B2828 detects a band of approximately 40kD in human spleen cell lysates.
