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".
Capable of inducing cell cycle arrest in G1 and G2 phases. Acts as a tumor suppressor. Binds to MDM2 and blocks its nucleocytoplasmic shuttling by sequestering it in the nucleolus. This inhibits the oncogenic action of MDM2 by blocking MDM2-induced degradation of p53 and enhancing p53-dependent transactivation and apoptosis. Also induces G2 arrest and apoptosis in a p53-independent manner by preventing the activation of cyclin B1/CDC2 complexes.
Immunohistochemical staining of sections from a wild type mouse testis taken at P11 were probed with LS-C2744 (green). Sections were stained with DAPI to reveal the position of cell nuclei (blue). This image was taken for the unconjugated form of this product. Other forms have not been tested.
Human Liver (formalin-fixed, paraffin-embedded) stained with CDKN2A antibody LS-B200 at 20 ug/ml followed by biotinylated secondary antibody, alkaline phosphatase-streptavidin and chromogen. This image was taken for the unconjugated form of this product. Other forms have not been tested.
Immunofluorescent detection of p19Arf using LS-C2744. Wild type mouse embryo fibroblasts (MEF) at passage 5 (panels 1, 2) and NIH3T3 cells, which have deleted the Arf gene (panels 3, 4) were probed with LS-C2744, followed by a fluorescently labeled anti-rat IgG secondary antibody (panels 1, 3). Cells were also stained with Hoechst dye to reveal the position of nuclei (panels 2, 4). This image was taken for the unconjugated form of this product. Other forms have not been tested.
Western blot analysis of endogenous p19Arf using LS-C2744. Total cell lysates (25 ug) from NIH3T3 cells, which have deleted the Arf gene (lane 1) and from wild type mouse embryo fibroblasts (MEFs) at passage 6, which express p19Arf (lane 2), were resolved by SDS-PAGE. This image was taken for the unconjugated form of this product. Other forms have not been tested.
Immunoprecipitation of p19Arf using LS-C2744. Total cell lysates (250 ug) from NIH3T3 cells which have deleted the Arf gene (lane 5) and from NIH3T3 cells expressing an HA-tagged version of p19Arf (lanes 3, 4) were incubated with control rat IgG (lane 3), or LS-C2744 (lanes 4, 5) and protein G- Sepharose. Precipitated proteins were resolved by SDS-PAGE and analysed by Western blotting using an anti-HA antibody. Unprecipitated total cell lysates (25 ug, equivalent to 10% of immunoprecipitation) f. This image was taken for the unconjugated form of this product. Other forms have not been tested.
