CD27 is a member of the tumor necrosis factor receptor superfamily that plays a central role in regulating lymphocyte activation, survival, and differentiation. Expressed primarily on T cells, B cells, and natural killer cells, CD27 engagement with its ligand CD70 delivers critical costimulatory signals that shape adaptive immune responses. This makes CD27 a compelling target for researchers investigating immune checkpoint biology, T cell memory formation, and immunotherapeutic strategies in oncology.
This recombinant monoclonal antibody, clone 4A1, offers the reproducibility and consistency that demanding experimental workflows require. Because recombinant antibodies are produced from defined genetic sequences rather than hybridoma supernatants, you can expect uniform performance across lots, eliminating a common source of variability in longitudinal studies. The antibody was raised in rabbit against a synthetic peptide derived from human CD27 and purified by affinity chromatography, ensuring high specificity for your target.
Validation by western blot demonstrates reliable detection across multiple human cell lines, including Daudi, HL-60, THP-1, and K562 lysates at a 1:1000 dilution. The observed band appears at approximately 55 kDa rather than the predicted 30 kDa molecular weight, a difference attributable to extensive glycosylation characteristic of this transmembrane receptor. This post-translational modification is well-documented for CD27 and confirms detection of the mature, physiologically relevant protein form.
With validated performance in both ELISA and western blot applications, this antibody provides flexibility for researchers working across cancer biology, immunology, and stem cell research. Whether you are characterizing immune cell populations or investigating costimulatory pathways in tumor microenvironments, this reagent delivers the specificity and batch-to-batch reliability essential for meaningful results.
