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".
49 kDa. DTT-reduced protein migrates as 50-65 kDa polypeptide due to glycosylation
HEK 293 Cells
Greater than 98% by SDS-PAGE
Measured by its ability to cleave a fluorescent peptide substrate Mca-Ser-Glu-Val-Asn-Leu-Asp-Ala-Glu-Phe-Arg-Lys(Dnp)-Arg-Arg-NH2. Cleavage of the substrate can be measured using excitation and emission wavelengths of 320 and 405 nm, respectively. The specific activity is > 7.5 pmoles /min /µg.
Less than 1.0 EU/µg protein (determined by LAL method).
Lyophilized from PBS, pH 7.4, 5-8% 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.
Responsible for the proteolytic processing of the amyloid precursor protein (APP). Cleaves at the N-terminus of the A-beta peptide sequence, between residues 671 and 672 of APP, leads to the generation and extracellular release of beta-cleaved soluble APP, and a corresponding cell-associated C-terminal fragment which is later released by gamma-secretase.
