CD70, also known as CD27 ligand or TNFSF7, is a type II transmembrane glycoprotein belonging to the tumor necrosis factor superfamily. This costimulatory molecule plays a critical role in T cell activation, B cell differentiation, and natural killer cell function through its interaction with CD27. CD70 expression is typically restricted to activated immune cells under normal physiological conditions, but aberrant expression has been documented across numerous malignancies, making it an attractive target for immunotherapy research and cancer biology studies.
This recombinant monoclonal antibody, clone 3B11, offers researchers the consistency and reliability that comes with sequence-defined production. Unlike traditional hybridoma-derived antibodies, recombinant technology ensures lot-to-lot reproducibility, allowing you to confidently compare results across extended studies without concerns about batch variation affecting your data.
The antibody has been validated for flow cytometry applications, providing flexibility for researchers investigating CD70 surface expression on human cells. Validation studies using Raji cells, a Burkitt lymphoma B cell line known to express CD70, demonstrated clear positive staining with strong signal separation from isotype control when used at 1:100 dilution. This performance on a well-characterized human lymphoma cell line confirms the antibody's utility for detecting CD70 on activated or malignant immune cell populations.
Supplied in a glycerol-based PBS buffer for stability, this unconjugated format allows pairing with your secondary antibody of choice, offering detection flexibility across experimental setups. Whether you are investigating CD70's role in immune checkpoint biology, exploring its potential as a therapeutic target, or characterizing tumor immunophenotypes, this antibody provides a dependable tool for your research workflow.
