Target: CD27.
Clone: RM27-3E5.
Specificity: RM27-3E5 activity is directed against mouse CD27.
Purification method: This monoclonal antibody was purified using multi-step affinity chromatography methods such as Protein A or G depending on the species and isotype.
Antigen Distribution: CD27 is expressed on T cells, B cells, and NK cells.
Background: CD27 is a glycosylated, type I transmembrane protein of the TNFR superfamily that is constitutively expressed on the surface of progenitor and naïve T cells as well as subsets of natural killer (NK) and B cells. CD27 is an immune-checkpoint receptor and ligation with CD70 results in co-stimulatory effects that enhance primary, memory, and recall T cell responses. CD27 signaling has been targeted for the development of viral, autoimmune, and anti-tumor immunotherapies.RM27-3E5 (rat IgG2a) was raised against recombinant mouse CD27-human IgG1 Fc fusion protein and purified from ascites using protein G columns. RM27-3E5 enhances anti-CD3-stimulated T cell proliferation when immobilized in vitro and augments ovalbumin-specific cytotoxic T lymphocyte (CTL) induction when administered in vivo.RM27-3E5 is an agonistic antibody and has been found to support the control of both established lung metastases and subcutaneous tumors. An anti-tumor effect was also observed with RM27-3E5 against EG7/CD27(+) and EG7/CD27(−) tumors, with the effect mediated mainly by T cells with a minor contribution by NK cells. RM27-3E5 exerts its potent anti-tumor effect by inducing a tumor-specific CTL response. RM27-3E5 has potential utility as a non-depleting agonistic anti-CD27 mAb to enhance anti-tumor immunity.
