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 interaction with its receptor 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 28E12, offers the reproducibility and consistency that demanding experimental workflows require. Because the antibody sequence is defined and production occurs in controlled recombinant systems, researchers can expect minimal lot-to-lot variation, ensuring that results remain comparable across extended studies and collaborative projects. The mouse IgG2a isotype and affinity-chromatography purification further contribute to reliable performance in sensitive applications.
Validation for flow cytometry demonstrates clear detection of CD70 on 786-O renal cell carcinoma cells, with recommended dilutions ranging from 1:50 to 1:200 providing flexibility for optimization across different experimental conditions. The distinct shift observed in surface staining confirms specific recognition of membrane-expressed CD70, supporting its utility in characterizing CD70-positive cell populations. Cross-species reactivity with both human and mouse samples extends the antibody's value for researchers working with preclinical models alongside human specimens.
Whether investigating immune checkpoint mechanisms, exploring CD70 as a therapeutic target in oncology, or characterizing tumor microenvironment interactions, this antibody provides a dependable tool for advancing understanding of CD70 biology in both basic research and translational applications.
