  • Immunohistochemistry Services

  • 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

RRM2B / P53R2 antibody was raised against anti-Human RRM2B/p53R2 antibody was prepared by repeated immunizations with a synthetic peptide corresponding to a region near the N-terminus of human RRM2B1 protein. A residue of cysteine was added to facilitate coupling.
Anti-Human RRM2B/p53R2 is directed against RRM2B and reacts with the RRM2B from human tissues. Based on sequence we expect this antibody to react as well with RRM2B from other species. Based on 100% homology to the immunizing sequence, one may expect reactivity to chimpanzee and orangutan; based on 93% homology, reactivity to macaque, and 92% to pig and Drosophila.
RRM2B/p53R2 antibody is suitable for IP, IHC, IF, ELISA and western blotting. Specific conditions for reactivity should be optimized by the end user. Expect a band approximately 41 kD in size corresponding to RRM2B1 by western blotting in the appropriate cell lysate or extract.

The p53 tumor-suppressor gene integrates numerous signals that control cell life and death. Several novel molecules involved in p53 signaling, including p53R2, Chk2, p53AIP1, Noxa, PIDD, and PID/MTA2, were recently discovered. p53R2 is a p53 inducible gene that contains a p53 binding sequence and encodes a subunit of the enzyme ribonucleotide reductase. p53R2 is induced by the reagents, ultraviolet and g-irradiation that cause DNA damages.

Western blot

Western blot
Anti-RRM2B antibody - Western Blot. Western blot of affinity purified anti-RRM2B antibody shows detection of recombinant (lanes 1 and 3) and endogenous protein (lanes 1 to 4) in whole cell extracts from transfected 293T. Lane 1 contains purified recombinant human p53R2. Lane 2 contains 293T cells transfected with control vector. Lane 3 contains 293T transfected with p53R2-myc. Lane 4:293T transfected with ScRNA. Lane 5:293T transfected with p53R2 SiRNA The band at 40.7 kD, indicated by the bottom arrowhead, corresponds to the expected molecular weight of endogenous RRM2B. The band with the middle arrow corresponds to myc-tagged p53R2 at 41.9kD. The highest band at 44.3 kD corresponds to recombinant p53R2. Primary antibody was diluted to 1 ug/mL and incubated overnight at 4C. ECL detection was used.
