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".
TRXR1 / TXNRD1 is a member of the family of pyridine nucleotide oxidoreductases. This protein reduces thioredoxins as well as other substrates, and plays a role in selenium metabolism and protection against oxidative stress. The functional enzyme is thought to be a homodimer which uses FAD as a cofactor. Each subunit contains a selenocysteine (Sec) residue which is required for catalytic activity. The selenocysteine is encoded by the UGA codon that normally signals translation termination.
ICC: CMXRos (a mitochondrial marker; 1:8000 dilution; Molecular Probes; red staining) was added to U937 cells growing in suspension, which were then incubated at 37°C for 30 min. Cells were fixed in paraformaldehyde and permeabilized. Cells were then incubated in blocking buffer (5% normal goat serum in PBS plus 0.05% Tween 20), and then in anti-TrxR1 (TrxR1; 1:100 dilution; green staining). After washing, cells were incubated with an anti-rabbit-Alexa 488 secondary antibody conjugate (1:100 dilution; Molecular Probes), washed, mounted in DAPI (blue staining) containing medium, and visualized in an Olympus IX71 confocal fluorescent microscope.
